What version of Fabric does Cello support? (I couldn't find the answer on the repo README.) What is the stage of development? (still active development? alpha? beta? stable?)

What version of Fabric does Cello support? v0.6 or v1.0a? (I couldn't find the answer on the repo README.) What is the stage of development? (still active development? alpha? beta? stable?)

holocron (Wed, 05 Apr 2017 15:25:18 GMT):
@hshimo from my brief inspection this week, i would say it only has v.6 support currently. I would love to hear an answer on this question as well.

vishwass (Wed, 05 Apr 2017 15:39:05 GMT):
currently supports v0.6 still need to support v1.0

Do we have any example chain code to deploy on Cello worker node?

baohua (Fri, 07 Apr 2017 02:00:07 GMT):
Now cello only provides fabric clusters, then u can use the original ways to deploy chaincode on the fabric cluster.

rohitbordia (Fri, 07 Apr 2017 03:55:09 GMT):
once we deploy manually the chaincode on worker nodes

rohitbordia (Fri, 07 Apr 2017 03:55:44 GMT):
we just need to change the ip address in node js example to connect to worker node rt?

SzaboZoltan (Sun, 16 Apr 2017 20:49:13 GMT):
@mikezaccardo I tried to follow https://github.com/cloudsoft/brooklyn-cello (great work really!) and make a cluster on AWS. It creates all the entities in the cloud but then the deployment fails due to ssh issues. "Error in task: ssh: Getting machine details for: SshMachineLocation...". It's funny that the EC2 instances have some kind of "jclouds#brooklyn-ooirql-amp-auto-gnn8-hyperledgercello-n2..." key pairs which is generated by the AMP/Brooklyn framework. Why are they not working?! Any experience?

SzaboZoltan (Mon, 17 Apr 2017 06:34:25 GMT):
@magg - yes, here: https://github.com/hyperledger/cello/blob/master/docs/install.md

mikezaccardo (Mon, 17 Apr 2017 14:27:26 GMT):
@SzaboZoltan You are correct in that AMP is generating a key pair that it will use to SSH into the VMs that it creates. I'm not sure why you experienced that error. Can you please send me your location configuration (with identity + credential removed) and any additional output from the app inspector console that relates to the error?

SzaboZoltan (Tue, 18 Apr 2017 05:11:03 GMT):
I think it will be an sshj problem.

@magg I am not a professional in this theme.

There is an "install.command:" part in both section; it is really useful to follow this. You should do the steps of the *master-node on your swarm master, and the worker(s) the "worker-node".

A question: if I successfully deploy a Cello system via https://github.com/cloudsoft/brooklyn-cello , is there a possibility to log in via ssh into one of the AMP/brooklyn created AWS machines? (Which has automatically generatid public key like "clouds#brooklyn-oom8n2-root-apr18-e2x7-hyperledgercello-ophu#23".)

mikezaccardo (Tue, 18 Apr 2017 18:35:25 GMT):
@SzaboZoltan Great to hear that you got it working! In order to manually SSH into the VMs that are created, you'll need to either configure the location to provide an SSH key from your machine or have an `~/.ssh/_id_rsa` key already there -- see this for more info: https://docs.cloudsoft.io/locations/reference/index.html

mikezaccardo (Tue, 18 Apr 2017 18:37:22 GMT):
For the configuration using a specific key on your machine, the location configuration would need a line like: `loginUser.privateKeyFile: /path/to/your/privatekey`

Good proof point that if someone has stood up a K8s cluster - in this case IBM Bluemix - we can derive an Apache Brooklyn location from the standard kubectl proxy config file

2 questions: Iis it possible to put into the blueprint, that I would like to have "stopable" VMs? The default possibilities is now are only "reboot, terminate" due to the lack of EBS entity. When I try to change shutdown behavior: >>An error occurred while changing the shutdown behavior of this instance: The instance 'i-04aab97d9f4423c98' does not have an 'ebs' root device type.<< | And also I would like to have t2.micro VMs, not the expensive m3.large ones (due to minRam parameter). But if I eliminate minRam, it will be "...medium", not "micro".

mikezaccardo (Wed, 19 Apr 2017 19:17:23 GMT):
1. Do you mean a way to get the VMs to stop and then come back alive at a later time? I don't think that is possible just now. You can of course get the VMs to terminate through AMP by "expunging" the application. See screenshot:

hello I made a successful deployment of Cello in Grid5000.fr but I have a question. Can Cello only deploy a Blockchain in a Swarm worker machine ( 4 or 6 VP nodes)? We require to scatter the VP nodes of one Blockchain across different Swarm worker machine

magg (Fri, 21 Apr 2017 09:45:36 GMT):
Can I tell Cello to deploy say 20 VP nodes across 3 Swarm worker machines, for example?

@SzaboZoltan a hyperledger peer or validation peer

@magg Well, I don't know the exact relationship between nodes and peers and chains, but I suppose node=peer in this context.

ok yeah i meant to say peers... sorry. So I want to have many peers spread across the swarm... not only one swarm worker

magg (Fri, 21 Apr 2017 14:14:20 GMT):
and I only see the limit to add 4 or 6 peers

@here -- high level question. Concerto became Fabric Composer, but does not actually manage fabrics, rather concerning itself with participants, data models, transactions (micro chaincode from my perspective) and ledgers. Cello has retained its name and concerns itself with fabrics and chains (channels). It seems to me that these two should merge. Both are mostly stuck on v0.6 right now, although there are patches for v1 waiting to go into composer as soon as someone can figure out how to do that without killing momentum completely. So my question is whether Cello will be merged into composer (as it truly *is* a fabric composer), at least in name and style if not directly into the code base? And the second question is how the v1 port is going, as I find the differences to be rather staggering at the fabric and client levels (not so much at the chaincode level)?

baohua (Wed, 26 Apr 2017 05:34:42 GMT):
Thanks for the advice. Because the scopes are quite different (concerto to help design/compose chaincode, cello to help manage/operate chains and do analytics), i do not think it's good idea. However, we can first see how each other can cooperate together in real scenarios. The v1 support is in implementation. Also, there are on-going work to support more underly infrastructures like k8s.

baohua (Wed, 26 Apr 2017 05:34:42 GMT):

kletkeman (Wed, 26 Apr 2017 13:13:39 GMT):
@MikeMayori It is my understanding that Composer is going to work with all fabric deployments, and the v1 port is ready for merge according to discussion on rocketchat. Regarding Cello, not having the v1 port done yet is not quite the same as "abandoned". Could you specify more clearly why you think both technologies are effectively retired? Because that does not jive at all with my understanding. Thanks.

kletkeman (Wed, 26 Apr 2017 13:17:41 GMT):
@baohua I understand that the scopes are quite different, but they overlap considerably. For example, there is a great opportunity to link Participants in the Composer data model to organizations and channels in Cello. At the least, the two should work together seamlessly, and at best they should be one Fabric Composer tool with a complete set of abilities to define and deploy fabrics in various configurations.

The composer runtime does implement JavaScript microservice transactions, but they are all linked in the service of one network definition (forgot the name they use). If we leave the concepts too widely separated, then we run the risk of slowing adoption when the two are used together. An **either / or** situation would be damaging I think.

baohua (Wed, 26 Apr 2017 13:19:08 GMT):
thanks kletkeman, it would be interesting to see how to adopt ur mentioned model into Cello. Currently we do not cover much on the chaincode management, although there're some jira issues proposed by some people want to implement.

baohua (Wed, 26 Apr 2017 13:19:48 GMT):
So as the first step, we still wanna let Cello to handle well at the deployment and operation work over those blockchains like fabric, stl and iroha.

kletkeman (Wed, 26 Apr 2017 13:21:12 GMT):
@baohua Ok, so the focus is swarms and traditional Go and Java chaincodes, correct?

baohua (Wed, 26 Apr 2017 13:22:06 GMT):
Then we would like to see if it can handle more onto the front end, at that time, it may be interesting to see if people would like to use Cello to design and write the js transactions. I think I understand the fabric-composer project well as it's still incubated internally, and its target is to help design chaincode with high-level programming language like javascript, by removing the effort to write golang code from the scratch.

baohua (Wed, 26 Apr 2017 13:22:47 GMT):
Similar discussions happen before in the community, actually.

baohua (Wed, 26 Apr 2017 13:23:59 GMT):
The conclusion is that hyperledger is a collaborative projects, that would encourage the collaborations among various projects, and no need to group into unique one. e.g., the fabric, stl, iroha, all are ledger platforms, but we should welcome all existing. How do u think?

kletkeman (Wed, 26 Apr 2017 13:24:12 GMT):
Yes, I am working with composer right now. It works with fabric definitions that enable security for Participants etc. Cello would never be used to design and write Composer chaincode, as that is what Composer does. But the business network definition (perhaps an instance of a system on a larger fabric) would be a good integration point.

baohua (Wed, 26 Apr 2017 13:25:32 GMT):
Maybe, but pls know that we do not wanna limit to fabric itself, hence we need to evaluate whether it will block cello to manage other blockchains like stl and iroha, to import such a fabric business work definition.

kletkeman (Wed, 26 Apr 2017 13:26:04 GMT):
For example ... define a complete system that uses smart contracts (or the finer grained transactions in composer) and export the BNA file, translating that as input to Cello, which orchestrates the creation of a working network based on parameters defined in Cello.

kletkeman (Wed, 26 Apr 2017 13:26:14 GMT):
Something like that would be pretty useful.

baohua (Wed, 26 Apr 2017 13:26:24 GMT):
Recently there are also related discussions. But we are open to all possible ideas, and welcome for advices.

baohua (Wed, 26 Apr 2017 13:26:41 GMT):
BNA file seems like some template?

kletkeman (Wed, 26 Apr 2017 13:27:23 GMT):
Ok, if Cello wants to be all singing and all dancing then that could override detailed integrations to specific tooling etc. for some time to come.

kletkeman (Wed, 26 Apr 2017 13:28:03 GMT):
BNA is a Business Network Archive, defining everything about a Composer based definition. Data model, Participants, Transactions and their implementations.

baohua (Wed, 26 Apr 2017 13:28:20 GMT):
And would BNA support blockchain platform besides fabric? If so, i personally feel interested to see whether we can together design some common/abstract format on general blockchain platform.

baohua (Wed, 26 Apr 2017 13:28:20 GMT):

kletkeman (Wed, 26 Apr 2017 13:30:12 GMT):
Presumably, someone could support blockchains other than Fabric with BNA. But that requires significant development resources, and getting one to work well should take priority in my opinion. For example, while Fabric and Ethereum state similar goals, Fabric has quite a different view of how to meet those goals. Trying to stay at the 10,000 foot level just means that a tool cannot service either well ...

baohua (Wed, 26 Apr 2017 13:30:38 GMT):
And it's not about all singing/dancing, as we proposed from the beginning of the project, we wanna provide more opinions for those potential hyperledger users. You can see there're various solutions by using different hyperledger tools. There were some specific "tool-suite" discussions before, too.

kletkeman (Wed, 26 Apr 2017 13:32:57 GMT):
Ok, I was not around at that time. I'm more focused on getting to the point where a detailed deployment with a complete definition can be performed easily. That requires pushing forward on one set of technologies. I will follow Cello as a non-integrated tool for now. It looks like it could prove very useful even without tight integration to tools like composer. Thanks.

baohua (Wed, 26 Apr 2017 13:32:58 GMT):
yeap, that's exactly what we are working on now. We noticed that such an abstract might be too difficult to finish everything. So we plan to start by supporting several. And since there's long roadmap to take, it would be a little too earlier to say which is the "best-practice". Actually, best-practice is coming from practices. Would u agree that?

baohua (Wed, 26 Apr 2017 13:35:00 GMT):
However, i would welcome u help open a jira issue to track the idea of letting cello support your BNA format. We definitely would like to support/work with more hyperledger projects. https://jira.hyperledger.org/projects/CE/issues. Thanks!

kletkeman (Wed, 26 Apr 2017 13:35:07 GMT):
I think we are just now developing an understanding of the value of blockchains in certain scenarios, and we are moving towards the ability to deploy Fabric on multiple topologies using multiple container technologies etc. So best practices will change as the Fabric community gets experience with real deployements over time.

kletkeman (Wed, 26 Apr 2017 13:36:19 GMT):
I'm not in the Composer team, but I will certainly look over them both if I can find the time. I have been hoping to find a tool to ease the pain of deploying complex Fabrics. Docker-compose helps a lot, but I don't think it's the solution ... just one piece.

baohua (Wed, 26 Apr 2017 13:36:56 GMT):
yeap, it will change, we have tried many topologies also, and find the underly technique is important, while there are also many key values from business, management and security conditions. That's really helpful if we can give some guideline/spec. That's also why the TWGC is working on the guideline/spec.

baohua (Wed, 26 Apr 2017 13:38:06 GMT):
I think u're talking about the operation, not only the deployment. the deployment usually happens once, while operations are more persistent and complex.

baohua (Wed, 26 Apr 2017 13:38:38 GMT):
We wanna start from deployment, and then evolve with more operational supports

baohua (Wed, 26 Apr 2017 13:39:17 GMT):
That's what we talk about the "management of blockchain", open to the smart contracts, too, if we believe it's part of the blockchain.

kletkeman (Wed, 26 Apr 2017 13:39:20 GMT):
Yes, I see them as the same thing, because deployments evolve over time. Added Participants usually imply added endorsers / orderers / observers ... that kind of thing. The ability to deploy all that automatically after updating a business network definition would be magical.

kletkeman (Wed, 26 Apr 2017 13:39:47 GMT):
And added participants can join channels, so everything is interconnected.

baohua (Wed, 26 Apr 2017 13:40:28 GMT):
Agree, let's help contribute into those hyperledger projects/tools, and make this real someday soon.

kletkeman (Wed, 26 Apr 2017 13:41:14 GMT):
Sounds like a good idea ... I'll poke around a bit more. I also have a chaincode platform for IoT contracts that could benefit, and it is traditional Go language.

baohua (Wed, 26 Apr 2017 13:41:32 GMT):
And would like to thanks a lot for proposing so many nice advices~~

kletkeman (Wed, 26 Apr 2017 13:41:55 GMT):
You are very welcome. We all have a lot to gain if anything like this can be made to happen.

baohua (Wed, 26 Apr 2017 13:42:23 GMT):
Yeap, and the business value are more likely at the higher layers :)

kletkeman (Wed, 26 Apr 2017 13:43:16 GMT):
Even with limitations, orchestration of business networks (as defined by BNA format for example) is a big deal once extended to Fabric topologies.

baohua (Wed, 26 Apr 2017 13:44:31 GMT):
aha, say how much would u like to pay for using the fabric-composer (BNA)?

baohua (Wed, 26 Apr 2017 13:44:31 GMT):

Feel like I've missed out on a good debate here ;-)

sstone1 (Sat, 29 Apr 2017 14:48:43 GMT):
@MikeMayori where did you get the impression that "Composer will only work in IBM Bluemix Premises"? We work against all Hyperledger Fabric v0.6 and v1.0 instances. We would not have been accepted as a top level project by the Hyperledger TSC if we only worked on IBM Bluemix.

sstone1 (Sat, 29 Apr 2017 14:49:49 GMT):
And following on from that, Composer today does support Hyperledger Fabric v1.0... the pending work is to update the playground to support connections to real Blockchain platforms (which _should_ go in this week).

sstone1 (Sat, 29 Apr 2017 14:52:20 GMT):
> For example, there is a great opportunity to link Participants in the Composer data model to organizations and channels in Cello This is something the Composer team is already discussing - we are talking about a "binding" between the Composer data model and the Fabric topology.

sstone1 (Sat, 29 Apr 2017 14:55:57 GMT):
> And would BNA support blockchain platform besides fabric? The Composer code base is 90-95% independent of the Blockchain platform. The remaining Blockchain platform specific code is completely pluggable, so adding support for the Sawtooth, Iroha, Burrow platforms is something that is totally possible. Indeed I had a good discussion in DC last week with the Burrow guys about how we could link up Burrow and Composer.

sstone1 (Sat, 29 Apr 2017 14:56:34 GMT):
And I agree that Cello should continue to support multiple deployment formats and Blockchain platforms :)

sstone1 (Sat, 29 Apr 2017 14:57:07 GMT):
I understand people still wanting to write chaincode, but also the possibility of someone building a new higher level framework on top of Composer.

sstone1 (Sat, 29 Apr 2017 14:58:01 GMT):
But the idea of being able to give a BNA to Cello and have Cello deploy a Fabric instance and the BNA + Composer chaincode to that instance is very interesting...

sstone1 (Sat, 29 Apr 2017 14:59:20 GMT):
If/when we add the binding between the Composer business network and the Fabric "physical" network then Cello could consume that binding information in order to determine what nodes/channels to lay out

sstone1 (Sat, 29 Apr 2017 14:59:42 GMT):
@baohua @kletkeman ping for the above ;)

baohua (Sun, 30 Apr 2017 13:45:13 GMT):
exactly, one interesting point is to use BNA model as the bridge. I would welcome if anyone wanna create a jira task on this.

``` sudo systemctl stop docker.service dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --api-cors-header='*' --default-ulimit=nofile=8192:16384 --default-ulimit=nproc=8192:16384 -D & ``` This will run the docker daemon on the specified host in the background, I've tested and working very well.

@indirajith would u have a look at https://github.com/yeasy/docker-compose-files/tree/master/hyperledger/1.0? I guess the exit is because the running of orderer cmd fails

bmkor (Sun, 28 May 2017 13:07:56 GMT):
I see. Thanks.

Yes. I am particular interested in how data analysis being carried out.

sure, bmkor, currently we collect logs and analyze using ELK. more features are adding, welcome for any idea

bmkor (Sun, 28 May 2017 13:56:52 GMT):

aha, thanks for the comments, bmkor, i guess there's no limit on what we can do after collecting those data from the network. would u like to help create a cello jira task to see if there's more disucssion on this idea?

for this, I wanna know how swarm supports orchestration here!. anyone help please

baohua (Thu, 01 Jun 2017 06:28:13 GMT):
basically, the swam provided similar restful api with docker. and it also support overlay networking across hosts.

chawlanikhil24 (Thu, 01 Jun 2017 06:38:17 GMT):
@baohua so we use any script to call those API of DOcker and Swarm ?

baohua (Fri, 02 Jun 2017 01:36:18 GMT):
we use compose files to call those APIs to help boot up containers, you can see the code under https://github.com/hyperledger/cello/blob/master/src/agent/docker

dstarina (Thu, 08 Jun 2017 07:42:02 GMT):
Hi. I have installed Cello using the manual here: https://github.com/yeasy/cello/blob/master/docs/deployment.md. Had some problems with docker daemons seeing each other, so from the file /etc/systemd/system/docker.service.d/override.conf I removed "-H fd:// $DOCKER_OPTS" (this stackoverflow resolution: https://stackoverflow.com/questions/44411828/cannot-connect-to-the-docker-daemon-port-2375?noredirect=1#44412406), and added '{"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}' to file /etc/docker/daemon.json. I did everything else exactly per instructions, and the installation seemed go to through fine, without any errors. However, when opening the dashboard (hostname:8080), after entering credentials (admin/pass), I get "404 Not Found". Did I miss something? How can I debug this?

chawlanikhil24 (Thu, 08 Jun 2017 11:25:47 GMT):
have you confirmed that docker is running of port localhost:2375 ?

chawlanikhil24 (Thu, 08 Jun 2017 11:26:35 GMT):
netstat | grep "2375

chawlanikhil24 (Thu, 08 Jun 2017 11:26:35 GMT):
netstat | grep "2375"

dstarina (Thu, 08 Jun 2017 11:44:10 GMT):
the netstat command doesn't get me any results

dstarina (Thu, 08 Jun 2017 11:45:16 GMT):
however, "docker -H 10.101.35.60:2375 version" does connect successfully

baohua (Thu, 08 Jun 2017 11:49:45 GMT):
so u can access the dashboard at hostname:8080, but after the credential entering, the page show 404?

baohua (Thu, 08 Jun 2017 11:50:58 GMT):
can u check if there's any error in the logs? `docker-compose logs -f`

baohua (Thu, 08 Jun 2017 11:52:13 GMT):
and also `docker ps -a` to show the running containers

dstarina (Thu, 08 Jun 2017 11:54:30 GMT):
Yes, that is correct - i can access it (get prompted for username/password), but the get 404

dstarina (Thu, 08 Jun 2017 11:54:30 GMT):
Yes, that is correct - i can access it (get prompted for username/password), but then get 404 after entering credentials

there's known problem with latest docker-compose version, which conflicts with docker-py

by the way, can u follow the steps at https://github.com/hyperledger/cello/blob/master/docs/install.md for a fresh installation? it's strange to have this problem. we will need to see the cause, thanks!

to 1.9?

I followed the steps at that link exactly (I can of course do it again), except for this:

dstarina (Thu, 08 Jun 2017 12:38:30 GMT):
I don't know much about docker so I don't know whether these changes could be the problem?

chawlanikhil24 (Thu, 08 Jun 2017 12:49:41 GMT):
@baohua should this be an issue on JIRA ?

baohua (Thu, 08 Jun 2017 12:50:25 GMT):
sure, pls help create a jira issue first, let's explore that more...

baohua (Thu, 08 Jun 2017 12:50:52 GMT):
@dstarina usually as all codes are running inside container, the version is fixed inside those containers.

chawlanikhil24 (Thu, 08 Jun 2017 12:51:11 GMT):
I am using docker-compose 1.8 and it worked with the official documentation provided on github @dstarina

baohua (Thu, 08 Jun 2017 12:51:42 GMT):
can i know the os info on ur running host? @dstarina

baohua (Thu, 08 Jun 2017 12:53:17 GMT):
yeap, at least 1.7~1.9, we have tested that :)

dstarina (Thu, 08 Jun 2017 13:49:13 GMT):
I'm running Ubuntu 16.04

dstarina (Thu, 08 Jun 2017 13:49:48 GMT):
docker-compose was installed together with docker, what docker version should I install then?

baohua (Thu, 08 Jun 2017 13:56:13 GMT):
aha, i suppose both docker 1.12 and 1.13 should work

baohua (Thu, 08 Jun 2017 13:56:47 GMT):
and the config u made should have nothing related to the error log, i guess

baohua (Thu, 08 Jun 2017 13:56:47 GMT):

@baohua just did that (before reinstalling docker). Same problem remains

does it help you if I send the exact set of commands I used to install this?

dstarina (Thu, 08 Jun 2017 14:31:55 GMT):
together with the docker install, can send you basically the whole set of commands I used to set this up from the fresh install

Wondering if we can connect IoT stuff to the fabric?

baohua (Fri, 09 Jun 2017 04:07:57 GMT):
i like IOT, but not sure ur idea, could u help provide more details?

chawlanikhil24 (Fri, 09 Jun 2017 06:19:18 GMT):
IOT in blockchain, I am curious to know how it can be achieved? @bmkor

bmkor (Fri, 09 Jun 2017 06:20:50 GMT):
I am just wondering. Say I got many weather temperature sensors, distributed all over a region. Can each sensor serve as a peer?

bmkor (Fri, 09 Jun 2017 06:23:24 GMT):
Precisely, I got those sensors distributed all over the counties (or provinces). Each county would serve like an organisation in fabric and some sensors located in a particular country would be the peers under that organisation. No sure this analogy is appropriate.

bmkor (Fri, 09 Jun 2017 06:23:55 GMT):
just a wild thought

bmkor (Fri, 09 Jun 2017 06:41:19 GMT):
Any ideas?

chawlanikhil24 (Fri, 09 Jun 2017 07:03:01 GMT):
That sounds only like peer to peer connectivity, and what about the transactions in Blockchains , whose ledger has to be maintained by Blockchains, what they can be related to ?

baohua (Fri, 09 Jun 2017 07:09:24 GMT):
one way may be to serve the IoT device renting transactions atop blockchain... self-auto-renting

chawlanikhil24 (Fri, 09 Jun 2017 07:15:37 GMT):
@baohua can you explain a bit, new to these words

chawlanikhil24 (Fri, 09 Jun 2017 07:40:39 GMT):

chawlanikhil24 (Fri, 09 Jun 2017 09:18:37 GMT):
got the query solved

baohua (Fri, 09 Jun 2017 14:02:21 GMT):
@chawlanikhil24 u mean the values of the environment in the docker-compose files? it was set in the environments section, and can read the value of env variables at the host platform.

dstarina (Mon, 12 Jun 2017 07:07:17 GMT):
@baohua @chawlanikhil24 which Ubuntu version, docker engine version and docker-compose version do you use in your environments?

dstarina (Mon, 12 Jun 2017 07:12:37 GMT):
because docker engine 1.13 ships together with docker-compose 1.13, so I would love to know what you have installed

dstarina (Mon, 12 Jun 2017 07:12:48 GMT):
do you also use an older version of docker engine?

dstarina (Mon, 12 Jun 2017 12:19:41 GMT):
@baohua @chawlanikhil24 About the issue we were discussing (https://jira.hyperledger.org/projects/CE/issues/CE-54?filter=allopenissues). I have created a new environment from scratch. I have installed docker 1.12 and docker-compose 1.8.1. Even with this, I have exactly the same problem. I am attaching the logs, but I think the problem in the logs is the same as before.

maybe this is the reason for 404?

dstarina (Mon, 12 Jun 2017 13:32:16 GMT):
I didn't set any host yet, I didn't set swarm cluster or anything ... I only have this one machine running for now, is this a problem?

dstarina (Mon, 12 Jun 2017 14:21:40 GMT):
So I only have the master right now

baohua (Mon, 12 Jun 2017 14:27:10 GMT):
aha, pls check ur local containers at the master node, if there's exited or restarting ones, then must sth wrong with the service in the container.

baohua (Mon, 12 Jun 2017 14:48:20 GMT):
@dstarina i just find a clean ubuntu 16.04 os, and run `make setup` and then `make restart`.... seems everything is fine. so strange why your built out container has wrong issues. Can u help clean all the docker images, and run the cmds i posted?

chawlanikhil24 (Mon, 12 Jun 2017 15:04:06 GMT):
Try docker container prune

chawlanikhil24 (Mon, 12 Jun 2017 15:04:11 GMT):
docker image prune

chawlanikhil24 (Mon, 12 Jun 2017 15:04:51 GMT):

Then it seems there is something wrong with my installation process ... Because I made a fresh installation of Ubuntu from the installation CD and then followed the procedure once again ... could someone take a peek at my installation process? It is the exact process that I followed from completely fresh Ubuntu 16.04 installation. It is supposed to be following the procedure exactly, but maybe I misunderstood some step ...

dstarina (Tue, 13 Jun 2017 08:58:41 GMT):
@baohua If you would be so kind to remotely login and check, I will be really grateful ... But the machine is on our internal network. I will send you access credentials for VPN access to your IBM email, is that ok?

Thank you @chawlanikhil24 ! I really appreciate your help

baohua (Tue, 13 Jun 2017 10:40:53 GMT):
@dstarina i will have a look, beside, can i know what you will use cello for? It would be nice and helpful if we know what adoption scenarios the users are from :)

dstarina (Tue, 13 Jun 2017 10:44:37 GMT):
While Fabric on Bluemix is great, there are some companies that, even when considering using the cloud, don't want their data out of the country

dstarina (Tue, 13 Jun 2017 10:45:06 GMT):
So we're making a deal with external cloud provider with data centers inside the country

dstarina (Tue, 13 Jun 2017 10:46:22 GMT):
And we would like to use Cello so it helps us to quickly create blockchain networks to use blockchain as a service

dstarina (Tue, 13 Jun 2017 10:47:12 GMT):
In the future, there will probably be an option to create peers for one network on seperate machines?

dstarina (Tue, 13 Jun 2017 10:47:25 GMT):
And to maybe add another peer to an existing network?

baohua (Tue, 13 Jun 2017 10:55:20 GMT):
understand, dstarina. would u like to share the adoption info at https://wiki.hyperledger.org/projects/cello#adoptions? It would highly encourage the development team.

baohua (Tue, 13 Jun 2017 10:55:49 GMT):
And to ur question, the answer if yes for the fabric 1.0 blockchain type :) we are rushing to finish the support of it currently

dstarina (Tue, 13 Jun 2017 10:58:51 GMT):
I will gladly share the adoption info once we make the deal :) Can't right now because we are still early in the process

dstarina (Tue, 13 Jun 2017 11:00:36 GMT):
We appreciate the work you are doing, this is a great project and am glad to have found it

baohua (Tue, 13 Jun 2017 11:02:10 GMT):
aha, i login in, and find the reason...

baohua (Tue, 13 Jun 2017 11:02:20 GMT):
u are not using the latest code

dstarina (Tue, 13 Jun 2017 11:03:20 GMT):
I did this: git clone https://github.com/yeasy/cello

dstarina (Tue, 13 Jun 2017 11:03:29 GMT):
where can I find the latest code?

baohua (Tue, 13 Jun 2017 11:03:46 GMT):
the latest repo is at https://github.com/hyperledger/cello

baohua (Tue, 13 Jun 2017 11:03:52 GMT):
i move ur own version as cello-old

baohua (Tue, 13 Jun 2017 11:03:59 GMT):
and create a new cello dir with the latest code

baohua (Tue, 13 Jun 2017 11:04:03 GMT):
can u try with that?

dstarina (Tue, 13 Jun 2017 11:04:22 GMT):
ohhh, ok! thank you so much, I will give it a try and let you know!

dstarina (Tue, 13 Jun 2017 11:12:18 GMT):

chawlanikhil24 (Tue, 13 Jun 2017 11:20:09 GMT):
@baohua github/yeasy is that your repo ?

baohua (Tue, 13 Jun 2017 11:21:03 GMT):
great! before cello was accepted by hyperledger, i use that to develop the code. now it is frozen, as the latest code is at https://github.com/hyperledger/cello

dstarina (Tue, 13 Jun 2017 11:27:56 GMT):
One question: can I also use the master machine as a worker or is that a bad idea? :)

dstarina (Tue, 13 Jun 2017 11:37:26 GMT):
http://gerrit.hyperledger.org/r/cello and https://github.com/hyperledger/cello - are those two different repositories?

baohua (Tue, 13 Jun 2017 11:49:14 GMT):
no they are the same, the github one is a mirror of the gerrit one

baohua (Tue, 13 Jun 2017 11:49:46 GMT):
@dstarina i would suggest use another machine, to keep everything clean. unless u can handle potential issues :wink:

dstarina (Tue, 13 Jun 2017 12:07:25 GMT):
I'm just going to use another machine ;) I have issues with that, too. I get "failed to create host". Could it be a problem that I'm using docker 1.13 on the master machine and docker 1.12 on the worker?

dstarina (Tue, 13 Jun 2017 12:07:25 GMT):
I'm just going to use another machine ;)

dstarina (Tue, 13 Jun 2017 12:24:41 GMT):
Can I ask you a more "philosophical" question? Because I know I'm going to get asked this by a customer, and I don't even understand it myself. I understand the reasoning behind blockchain when each network participant (each company) has its own peer running. But on all the tutorial, and now even in Cello, we always install the network with multiple peers on one machine and I started doubting my understanding of this. Is this a viable production scenario, or is the reason behind it just creating a demo environment? Is there a scenario where having multiple peers on a single machine would make sense in production environment?

dstarina (Tue, 13 Jun 2017 12:25:15 GMT):
Is my understanding (having one peer per company) correct?

dstarina (Tue, 13 Jun 2017 12:33:40 GMT):
I'm asking because I only have an option of choosing either 4 or 6 peers when creating the chain :)

baohua (Wed, 14 Jun 2017 01:49:24 GMT):
david, if you let cello run atop a swarm cluster, then it will support multi-hosts, as the native Docker host only support single node :)

baohua (Wed, 14 Jun 2017 02:21:37 GMT):
Dear all, we plan to make a Cello meetup at the Hackfest in Beijing, pls feel free to join and share your thoughts, experience, and ideas. Thanks! https://wiki.hyperledger.org/groups/twgc/hackfest-beijing

chawlanikhil24 (Wed, 14 Jun 2017 06:59:59 GMT):
[ ](https://chat.hyperledger.org/channel/cello?msg=6J5E6Ti8D7t3MWhox) @baohua you mean, like each worker node in swarm running cello itself ?

baohua (Wed, 14 Jun 2017 07:01:36 GMT):
Cello treat each worker node as a pool of resource, and will deploy blockchain inside. While for the swarm mode, we treat a swam cluster as a "logic worker node". There cello will leverage swarm's overlay network to deploy among various hosts managed by the swarm. is this clear to u?

chawlanikhil24 (Wed, 14 Jun 2017 07:01:41 GMT):
[ ](https://chat.hyperledger.org/channel/cello?msg=fJNcKZqNBNhrMyaZ7) @baohua Will it be covered live as well, Since I am in India and would like to be a part

baohua (Wed, 14 Jun 2017 07:02:47 GMT):

chawlanikhil24 (Wed, 14 Jun 2017 07:05:11 GMT):
[ ](https://chat.hyperledger.org/channel/cello?msg=mdk9xDyHn75P46rQS) @baohua Yupp absolutely clear, its like, multiple blockchain like, b1,b2,b3....bn are all running on cello and managed by Swarm overlay network ?

chawlanikhil24 (Wed, 14 Jun 2017 07:06:25 GMT):
In this case, I suppose if there are n blockchains, then n ip addresses too, to manage each worker blockchain cello dashboard ?

baohua (Wed, 14 Jun 2017 07:07:13 GMT):
sorry, not quite get ur question...

baohua (Wed, 14 Jun 2017 07:07:37 GMT):
in this case, 1 worker node === 1 swarm cluster (multi-hosts)

baohua (Wed, 14 Jun 2017 07:08:00 GMT):
the ip address is managed in the swarm cluster (overlay networking layer)

dstarina (Wed, 14 Jun 2017 07:08:17 GMT):
Guys, what is the reason the only options to choose when deploying a chain are 4 or 6 peers on HL 0.6 and 7 peers on HL 1.0? Is this because Cello is still in development - or am I wrong in assuming that in business network, each participant in a network (for example each company in a business network) should be responsible for one peer? Are peers supposed to be connected with network participants or are they only a way to achieve immutability and not really connected to business networks?

baohua (Wed, 14 Jun 2017 07:09:57 GMT):
david, as it's still under development, we provide some fixed number, to give some quick usage of a blockchain network. the dynamic joining feature will be supported soon.

baohua (Wed, 14 Jun 2017 07:10:14 GMT):
after we got the fabric 1.0 supporting feature done @chawlanikhil24

baohua (Wed, 14 Jun 2017 07:10:17 GMT):
@dstarina

dstarina (Wed, 14 Jun 2017 07:10:55 GMT):
ok, thank you for the answer, glad to hear

chawlanikhil24 (Wed, 14 Jun 2017 07:11:31 GMT):
cello will deprecate swarm for fabric 1.0 ?

chawlanikhil24 (Wed, 14 Jun 2017 07:11:51 GMT):
or wll it be a choice for the user to run on swarm or k8s ?

baohua (Wed, 14 Jun 2017 07:18:19 GMT):
both will be available

baohua (Wed, 14 Jun 2017 07:18:47 GMT):
that'd be better for the users to choice their own underly cluster type :)

@lujiang : Without a license, we cannot tell what the author intended the license to be. We either need to get the author to provide the license to determine whether it is compatible with the Apache 2.0 license or whether we will require an exception for inclusion of this file in the Cello source base. If we are unable to determine the license, is there an alternative that can be used?

can anyone help me regarding this!

duwenhui (Fri, 21 Jul 2017 01:32:35 GMT):
@baohua after make restart and make redeploy ， the host and chain data added brefore remaine exist.

baohua (Fri, 21 Jul 2017 01:33:39 GMT):
Thanks and congrats for ur 1st patchset! @markparz

baohua (Fri, 21 Jul 2017 01:34:23 GMT):
@duwenhui sorry cannot understand, u mean some new problem?

baohua (Fri, 21 Jul 2017 01:37:14 GMT):
@chawlanikhil24 which version of image are u using? Seems the address port is invalid? listen tcp 10.0.0.98:7052: bind: cannot assign requested address

baohua (Fri, 21 Jul 2017 01:37:43 GMT):
pls check whether some other process already occupy the address.

duwenhui (Fri, 21 Jul 2017 02:15:00 GMT):
@baohua Ubuntu 16.04 Update /lib/systemd/system/docker.service like [Service] DOCKER_OPTS="$DOCKER_OPTS -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --api-cors-header='*' --default-ulimit=nofile=8192:16384 --default-ulimit=nproc=8192:16384" EnvironmentFile=-/etc/default/docker ExecStart= ExecStart=/usr/bin/dockerd -H fd:// $DOCKER_OPTS Regenerate the docker service script and restart the docker engine: $ sudo systemctl daemon-reload $ sudo systemctl restart docker.service This operation does not seem to be successful？

baohua (Fri, 21 Jul 2017 02:17:54 GMT):
aha, i've tested in ubuntu 16.04, not sure if it was changed. anyone else meets similar issue?

baohua (Fri, 21 Jul 2017 02:18:15 GMT):
@chawlanikhil24 @hightall @indirajith

liutc (Fri, 21 Jul 2017 04:20:57 GMT):
@baohua I do not know what exact problem @duwenhui met. In my case, the DOCKER_OPTS does not work in ExecStart=/usr/... I have to replace that with the value, i.e. directly writing everything in the same line

chawlanikhil24 (Fri, 21 Jul 2017 04:24:13 GMT):
@baohua It was unsuccessfull on my ubuntu machine as far as I remember, that's why I added one alternative in a PR

indirajith (Fri, 21 Jul 2017 10:16:46 GMT):
@duwenhui @baohua Yes I remember, I could not make `$ docker -H Worker_Node_IP:2375 info` work with the method provided for Ubuntu 16.04. Then I went with the all other linux distro option twice and it worked for me.

baohua (Mon, 24 Jul 2017 02:00:35 GMT):
in recent ubuntu after 16.04, the os uses systemd to manage the bootup service, which is more complicated than the upstart. Hope we collect more usage cases to find a compatible way to add those docker options.

baohua (Fri, 28 Jul 2017 11:42:58 GMT):
strange, why the minimal width is 78 in ur env? i guess 79 should be ok... that should be related to ur flake8 default checking rule. can u verify?

CBTheis (Fri, 28 Jul 2017 20:32:46 GMT):
Has joined the channel.

Andy Zhang (Mon, 31 Jul 2017 04:48:00 GMT):
I think so. Looks like default max-line-length on Mac for flake8 is 78. Maybe we could configure this value and others in tox.ini file as said in http://flake8.pycqa.org/en/latest/user/configuration.html

baohua (Mon, 31 Jul 2017 05:28:15 GMT):
sure, feel free to help create a jira task and fix. i guess 79 is more common.

duwenhui (Tue, 01 Aug 2017 03:25:26 GMT):
@baohua duwenhui 下午2点45分 @smithbk I searched for the previous reply and still couldn't find the answer. I tried the ./fabric-ca-client enroll -u http://admin:adminpw@localhost:7055, which executed successfully. Can you tell a clearer solution? smithbk 2017年7月27日晚上8点09分 @duwenhui For some reason, the fabric-ca-server failed to start on port 7055. There must be an earlier error message indicating why. ``` Error: POST failure [Post http://localhost:7055/enroll: dial tcp [::1]:7055: getsockopt: connection refused]; not sending ```

duwenhui (Tue, 01 Aug 2017 03:27:45 GMT):
In this case ,I think that whenever I start a second CA server with a command and register and enroll i will make this error

@duwenhui wenhui, i guess the port should be 7054.

are u testing on a new chain started by cello?

duwenhui (Tue, 01 Aug 2017 06:23:07 GMT):
@baohua Not port, I started multiple CA server one port is 7054, and the other port is 7055. I haven't tested the new chain yet, and I will test it. I added the solo mode chuain a few days ago, but it was wrong when I deleted it.

@baohua I can't find the instructions of the document, please help to attach a specific connection.

tongli (Tue, 01 Aug 2017 12:52:47 GMT):
@Luke_Chen not sure what your goal is, but if you like, please take a look at this project. https://github.com/litong01/fabric-deploy

tongli (Tue, 01 Aug 2017 12:53:07 GMT):
use that project you can either setup docker swarm like env or k8s.

tongli (Tue, 01 Aug 2017 12:53:22 GMT):
the project then will deploy fabric on top of either.

tongli (Tue, 01 Aug 2017 12:54:26 GMT):
if you only are interested in how the docker swarm like env setup, you can look at this role. https://github.com/litong01/fabric-deploy/tree/master/roles/deploy_compose

tongli (Tue, 01 Aug 2017 12:54:57 GMT):
it uses docker-compose to deploy fabric onto a docker + overlay network.

tongli (Tue, 01 Aug 2017 12:55:09 GMT):
which is very similar to docker swarm env.

tongli (Tue, 01 Aug 2017 12:55:58 GMT):
but to truly look into how the overlay network gets setup, take a look at this role. https://github.com/litong01/fabric-deploy/tree/master/roles/env_flanneld/networksetup

baohua (Tue, 01 Aug 2017 14:00:07 GMT):
@Luke_Chen are u asking how to setup a swarm cluster of setup a fabric network on top of a docker swarm? For the first question, pls refer to the docker documentation. for the second one, it's quite easy to do that using cello. Just import the swarm cluster as a worker node in cello's dashboard.

Luke_Chen (Wed, 02 Aug 2017 02:57:47 GMT):
@baohua Thank you , but could you please tell me more details about swarm cluster ? It's that mean add docker swarm manager node ?

Luke_Chen (Wed, 02 Aug 2017 03:01:37 GMT):
@tongli Thank you for your response, I want to know how to trigger docker swarm mode in cello project.

baohua (Wed, 02 Aug 2017 03:02:49 GMT):
yes, to add existing swarm cluster into Cello, just input the manager API like a single Docker Host

baohua (Wed, 02 Aug 2017 03:03:03 GMT):
like x.x.x.x:2376

baohua (Wed, 02 Aug 2017 03:03:25 GMT):
remember to enable the overlay networking mode, hence u can have fabric over multi-hosts

Luke_Chen (Wed, 02 Aug 2017 03:03:47 GMT):
@baohua OK thank you very much

Let's keep refining as the review comments, I believe this would be a good beginning!

tongli (Tue, 22 Aug 2017 13:56:45 GMT):
there is an ansible driver in python to integrate ansible with python program.

yes, totally.

@here, need your advice, exposing peer containers to external endpoints will be a good move ? I guess its not safe from security point of view !

tongli (Wed, 23 Aug 2017 13:45:09 GMT):
well, peer and orders are eventually need to be accessible from client.

tongli (Wed, 23 Aug 2017 13:45:43 GMT):
in a real world production setup, they should be exposed to outside of your network.

chawlanikhil24 (Wed, 23 Aug 2017 13:46:00 GMT):
I guess, cli container serves the purpose

tongli (Wed, 23 Aug 2017 13:46:07 GMT):
otherwise how sdks (which get used by client) will be able to use them?

tongli (Wed, 23 Aug 2017 13:46:19 GMT):
ah?

chawlanikhil24 (Wed, 23 Aug 2017 13:46:30 GMT):
since, it can be connected to another peers and orderers

tongli (Wed, 23 Aug 2017 13:46:54 GMT):
cli container is something an admin may use.

tongli (Wed, 23 Aug 2017 13:46:59 GMT):
client can not use that.

chawlanikhil24 (Wed, 23 Aug 2017 13:47:25 GMT):
cli has an endpoint ! in my case

chawlanikhil24 (Wed, 23 Aug 2017 13:47:46 GMT):
I make it deliberately external

chawlanikhil24 (Wed, 23 Aug 2017 13:48:01 GMT):
so that , there should be only one accessible point to the whole cluster

chawlanikhil24 (Wed, 23 Aug 2017 13:49:24 GMT):
cli -> peer cli -> orderer cli -> other PODS using, ClusterIP

chawlanikhil24 (Wed, 23 Aug 2017 13:58:06 GMT):

tongli (Tue, 29 Aug 2017 13:17:34 GMT):
@Luke_Chen We have recently added ansible modules to cello which provisions VM against aws, openstack, azuer, VirtualBox.

tongli (Tue, 29 Aug 2017 13:17:52 GMT):
if you like to support vSphere, (VMWare), it is very easy to do that.

tongli (Tue, 29 Aug 2017 13:18:16 GMT):
simply add a provision module (few playbooks) for the provisioning.

tongli (Tue, 29 Aug 2017 13:19:03 GMT):
IBM lab uses vSphere (a bit of customized vSphere).

tongli (Tue, 29 Aug 2017 13:19:20 GMT):
Ansible provides VMWare ansible module.

tongli (Tue, 29 Aug 2017 13:20:33 GMT):
I think you can probably think about that. Once VM(s) are provisioned, then the next step of setting up fabric network will be identical to do the same against other cloud as AWS, OpenStack.

tongli (Tue, 29 Aug 2017 13:20:44 GMT):
let me know if you have more questions.

tongli (Tue, 29 Aug 2017 16:44:59 GMT):

tongli (Wed, 30 Aug 2017 13:30:51 GMT):
@baohua can you tell me how to configuration to cello is done? for example, if something needs to be set to a value, how the default is defined and how to specify a different value?

baohua (Wed, 30 Aug 2017 13:47:57 GMT):
@tongli hi tong, can i know what kind of configuration? for the cello service itself or for the fabric network?

tongli (Wed, 30 Aug 2017 13:48:15 GMT):
@baohua the docker port,

tongli (Wed, 30 Aug 2017 13:48:24 GMT):
it may not always run on 2375.

baohua (Wed, 30 Aug 2017 13:49:08 GMT):
yeap, when u specify a docker host as a "host" in cello?

tongli (Wed, 30 Aug 2017 13:49:15 GMT):
thinking making that configurable, default will be 2375, but people can make changes to the configuration file (if there is one) or env variable, so that the port will be different.

tongli (Wed, 30 Aug 2017 13:49:41 GMT):
I guess I am asking overall how configurable cello is.

tongli (Wed, 30 Aug 2017 13:49:54 GMT):
right.

baohua (Wed, 30 Aug 2017 13:50:56 GMT):
there are several places we using docker. If you mean importing a docker host, then it's simple. On the admin portal, you can specify the API url to whatever you want, e.g., 9.9.9.9:2376 (suppose there's a docker daemon listened)

tongli (Wed, 30 Aug 2017 13:53:28 GMT):
I can verify that. but I think I am asking what is the general mechanism to config cello? for example, what if someone wants the dashboard not being on 8080 but on 9090.

tongli (Wed, 30 Aug 2017 13:53:56 GMT):
is there a configuration file for cello so that once the installation is done, the dashboard goes to 9090 instead of 8080.

tongli (Wed, 30 Aug 2017 13:54:10 GMT):
also say I do not want to use admin:pass, I want to use something else,

tongli (Wed, 30 Aug 2017 13:54:19 GMT):
how is that getting done?

tongli (Wed, 30 Aug 2017 13:54:41 GMT):
I think I am asking for the general configuration mechanism of cello.

tongli (Wed, 30 Aug 2017 13:55:15 GMT):
if there is none, that is fine, we can add.

baohua (Wed, 30 Aug 2017 13:57:13 GMT):
yes, that's another question. and we now have a src/config.py file, which mainly configs web/mongo info. I guess we can feel free to extend from it. thoughts?

tongli (Wed, 30 Aug 2017 14:11:55 GMT):
cool. as long as there is a general way of configuration anything, that is good.

tongli (Wed, 30 Aug 2017 14:12:33 GMT):
the only drawback with python code is that people feel a bit intimidated changing code vs changing a yaml file or flat text file.

tongli (Wed, 30 Aug 2017 15:13:44 GMT):
Please review this patch. https://gerrit.hyperledger.org/r/#/c/12915/

tongli (Wed, 30 Aug 2017 15:14:13 GMT):
we need to add these cloud specific configuration files and these file also serve as templates.

baohua (Wed, 30 Aug 2017 15:31:05 GMT):
@chawlanikhil24 thanks, and let's add more docs and enable operate k8s based fabric using the dashboard.

@tongli pls follow the http://cello.readthedocs.io/en/latest/CONTRIBUTING/, and create a jira task for it. thanks.

tongli (Thu, 07 Sep 2017 01:37:47 GMT):
@baohua will do.

baohua (Thu, 07 Sep 2017 02:23:38 GMT):
@waaagh Currently there is no host-type specified from the dashboard, hence it may break the operation if we do not set at FE or use default value? https://gerrit.hyperledger.org/r/#/c/13127

waaagh (Thu, 07 Sep 2017 02:26:53 GMT):
@baohua if no host_type specified at FE, we will try to detect the type via docker api, not the default value

waaagh (Thu, 07 Sep 2017 02:27:46 GMT):
there's also a test case cover this case

baohua (Thu, 07 Sep 2017 02:28:18 GMT):
Thanks, i will recheck, and maybe we can add some host_type choice at FE? Then can make sure there's value from it. how do u think? in another pr?

baohua (Thu, 07 Sep 2017 02:28:53 GMT):
And could u help add the license header at https://gerrit.hyperledger.org/r/#/c/13127/4/test/cases/test_host_create.py

waaagh (Thu, 07 Sep 2017 02:28:57 GMT):
Yes, as u mentioned yesterday, a pull-down box is a good idea

baohua (Thu, 07 Sep 2017 02:29:01 GMT):
since u create it :)

waaagh (Thu, 07 Sep 2017 02:30:09 GMT):

@sk , For now, Cello project has manifests and scripts to setup fabric on Kubernetes

chawlanikhil24 (Mon, 11 Sep 2017 10:13:45 GMT):
but the Dashboard Control is still under development, there are mannually deployable manifests and Ansible scripts as welll

sk (Mon, 11 Sep 2017 10:15:58 GMT):
Thanks @chawlanikhil24, so can I install Cello manually using manifests on Bluemix Kubernets Cluster? Is this correct understanding?

Hi everyone, can i use cello with Hyperledger fabric to move from virtual to physical machines ?

tongli (Mon, 11 Sep 2017 12:22:56 GMT):
@rubi_1432 you want to do a relocation without losing the chain, I assume , is that right?

tongli (Mon, 11 Sep 2017 12:25:06 GMT):
In theory , you could add more peers from physical nodes, then run for awhile so that new nodes will establish the chains, once new nodes catch up, you could shutdown the virtual node

tongli (Mon, 11 Sep 2017 12:25:33 GMT):
I do not think you can do a direct copy sort of move.

i guess it might be u're using very latest version of docker. we mostly recommend to use 1.13. The new version of docker have behaviors changed.

@tongli Yes, i want to add peers from physical node. But i can't figure out how to do it. I am starting with connecting physical machines and then creating a channel over it using *Build your first network* tutorial. Is this the right direction ?

tongli (Mon, 11 Sep 2017 14:14:39 GMT):
@rubi_1432 I thought you already have a fabric network running, then you want to move to physical servers.

tongli (Mon, 11 Sep 2017 14:15:18 GMT):
if this is brand new env, then following the instruction should have worked since cello did not care if your node is virtual or physical

tongli (Mon, 11 Sep 2017 14:15:52 GMT):
or you can utilize what I recently contributed to setup multi-node fabric network by using ansible.

tongli (Mon, 11 Sep 2017 14:16:01 GMT):
which is at src/agent/ansible.

tongli (Mon, 11 Sep 2017 14:16:28 GMT):
look into a doc at src/agent/ansible/vars/README.md file for dealing with physical servers.

tongli (Mon, 11 Sep 2017 14:17:17 GMT):
if you need some help using the ansible script, I can certainly help out.

tongli (Mon, 11 Sep 2017 14:17:56 GMT):
at the end, you will be able to layout a fabric network on your physical server very easily.

rubi_1432 (Mon, 11 Sep 2017 14:20:07 GMT):

I cant login.

HenryZhang (Tue, 12 Sep 2017 01:49:08 GMT):
@hightall Thanks for your review. We will continue with more code soon.

yoyokeen (Tue, 12 Sep 2017 02:23:58 GMT):
what kind of people can join Cell? nodejs and others?

baohua (Tue, 12 Sep 2017 03:52:02 GMT):
@yoyokeen yeap, we didn't connect the user-dashboard now. will evaluate which solution is better.

baohua (Tue, 12 Sep 2017 03:52:42 GMT):
Cello is open to everyone, the backend is mostly written in python, while there are lots of code in javascript, css and html too.

baohua (Tue, 12 Sep 2017 03:53:13 GMT):
pls feel free to ping @hightall if you feel interested with the dashboard component. @yoyokeen

yoyokeen (Tue, 12 Sep 2017 03:53:39 GMT):
blockchain-explorer is alive?

yoyokeen (Tue, 12 Sep 2017 03:53:46 GMT):
@baohua

baohua (Tue, 12 Sep 2017 03:54:15 GMT):
yes, i believe so. you can feel free to reach the projects' maintainers.

baohua (Tue, 12 Sep 2017 03:54:29 GMT):
can find the maintainers.md at the git repo

baohua (Tue, 12 Sep 2017 03:54:35 GMT):
@HenryZhang Congrats to the vmware team, look forward to seeing more contributions!

yoyokeen (Tue, 12 Sep 2017 03:54:53 GMT):
there are some difference from blockchain-explorer and user-dashboard(cello)

baohua (Tue, 12 Sep 2017 03:58:34 GMT):
yes, there is

baohua (Tue, 12 Sep 2017 03:58:55 GMT):
maybe can take as a quick workaround until our user dashboard is done.

yoyokeen (Tue, 12 Sep 2017 05:28:00 GMT):
The user dashboard will replace the blockchain-explorer or the blockchain-explorer will been integrated by user dashboard.

AuHuR (Tue, 12 Sep 2017 08:00:08 GMT):
Hey folks, I'm unable to login to the dashboard. I'm getting a 401 error when I try to auth. I already double checked the user and password. Also changed the credentials in the docker-compose file to look if there is an error but I'm still getting the 401 error.

ArvsIndrarys (Tue, 12 Sep 2017 10:06:26 GMT):
Hello guys ! I was wondering if Cello was able to simply connect to a fabric instance instead of creating it? we already have fabric deployed and are considering adding cello to it. Is it possible to integrate it or should we start from scratch via Cello?

baohua (Tue, 12 Sep 2017 10:57:00 GMT):
@yoyokeen there're different, so no such kind of plan.

baohua (Tue, 12 Sep 2017 10:57:18 GMT):
@AuHuR can u check the logs of the containers on the master node?

baohua (Tue, 12 Sep 2017 10:58:11 GMT):
@sk mostly they are the same, except the docker installation part. after that, it's safe to run `make start`. and remember to create the db dir manually and mount to docker at MacOS.

baohua (Tue, 12 Sep 2017 10:58:48 GMT):
@ArvsIndrarys currently cello deploy fabric, instead of connecting to one. you may try the blockchain-explorer project.

sk (Tue, 12 Sep 2017 10:59:07 GMT):
Thanks @baohua mainly facing issues to find Docker config file /etc/default/docker on Mac OS

sk (Tue, 12 Sep 2017 10:59:28 GMT):
there is no Docker config file /etc/default/docker on Mac OS its only exist on Ubuntu/Linux

baohua (Tue, 12 Sep 2017 11:00:38 GMT):
no worry about it, as at MacOS, things are different. just follow the official steps to setup Docker.

baohua (Tue, 12 Sep 2017 11:01:07 GMT):
and remember to create and mount the db path into docker. and change its privilege to ur user role.

ArvsIndrarys (Tue, 12 Sep 2017 11:01:10 GMT):
@baohua thanks ! I'll look into it

baohua (Tue, 12 Sep 2017 11:01:34 GMT):
sure, and welcome to help add some docs to describe the steps on use Cello at MacOS.

baohua (Tue, 12 Sep 2017 23:31:59 GMT):
@AuHuR thanks. Yes, since react has license problem, we now use the basic theme by default. @hightall could u help confirm?

@AuHuR yes，now we stopped dev on react theme，and will rewrite basic theme with vue framework. So will you contribute code for the UI？:grinning:

Did you install tox ?

waaagh (Fri, 15 Sep 2017 01:39:13 GMT):
this happened in a jenkin job

harsha (Fri, 15 Sep 2017 01:39:49 GMT):
To me it seems tox isn't installed hence the issue.

waaagh (Fri, 15 Sep 2017 01:40:50 GMT):

@baohua, you asked me to provide a bit more details on what I suggested being an interface between UI and backend agent.

tongli (Fri, 15 Sep 2017 14:17:23 GMT):
Since I need to give you an example on what I meant, I thought that doing it here is probably a bit easier.

tongli (Fri, 15 Sep 2017 14:22:15 GMT):
The UI is a component which allows users to specify how nodes or fabric network should look like, it is a component gathers user request/intention, once the user request is collected, then that request gets sent to backend agent to perform actual work. So if we have a clear spec for user to describe their intention, then the UI can be developed any way a dashboard developer wants, the backend agents (fabric, sawtooth, Iroha, or whatever) can take that request, then perform the actual work accordingly.

tongli (Fri, 15 Sep 2017 14:22:43 GMT):
For ansible deployer agent, what I have is this.

tongli (Fri, 15 Sep 2017 14:22:50 GMT):
I believe that I have showed you.

tongli (Fri, 15 Sep 2017 14:26:35 GMT):
this type of file serves as a spec between UI and backend agent. regardless what backend you may have, a blockchain network can be specified as such. the spec can be quite different for different agents, but it will be a single yaml file.

tongli (Fri, 15 Sep 2017 14:27:05 GMT):
hope that helps.

@waaagh @baohua fixed, I re-ran the two failed builds

@rjones thanks!

baohua (Sat, 16 Sep 2017 02:46:03 GMT):
@tongli thanks for ur comments. Now i get ur idea. The dashboard discussed is actually for creating a new host. But i guess we can use some config files as u suggest to maintain the clusters we created. Currently we only suppose fixed size of network, this config file can be a good start for supporting use-defined blockchain network. One problem might be is it general enough for all blockchains (for fabric, it should be OK as adopted in those SDK projects already).

waaagh (Sat, 16 Sep 2017 06:25:46 GMT):
@hightall @baohua plz help review this patch, i add a pull-down box to let user chose the host_type https://gerrit.hyperledger.org/r/#/c/13461/

tongli (Mon, 18 Sep 2017 02:55:24 GMT):
@baohua for different type of block chains, that file can be different even in format. As long as the ui knows all it needs to do is to craft necessary field values from a file, the. The back end different agent will understand particular type of config file, then it is ok. For example, the ui for fabric may look quite different from the ui for sawtooth, but that is ok. The architecture is still intact. The server basically take ui fields from the dashboard component and pass to the corespondent agent. That flow won't change at all. With that, we can support any type of agent and ui.

tongli (Mon, 18 Sep 2017 02:57:42 GMT):

Hi. If I add chain with default certificates it initializes fine, but if I generate new certificates from a given crypto-config.yaml create channel gets unexpected status BAD_REQUEST.

thanks, tong, will review. and btw, do u know how to do the perf test now? Using PTE tool?

tongli (Tue, 19 Sep 2017 01:18:39 GMT):
@baohua for the performance test, we have been doing it manually. Now with the ansible agent, we can automatically provision vms, built and deploy fabric network with different layout, so that performance test can be done automatically. We are in process to run the entire performance test on ci and collect data for each run and make the result public

I could setup and run Cello (master + worker) successfully and also created host and active chains. (1) How can I deploy chaincode (*.go files) program into active-chain network? (2) how can I access different method of that deployed chaincode?

baohua (Fri, 22 Sep 2017 01:14:50 GMT):
@sk currently we do not enable the user dashboard for help operate the chaincode. but after the chain bootup, it will expose the access API url, and you can feel free to use the sdk to call those API's.

yes, then u can use sdk to operate the chaincode using the API.

sk (Fri, 22 Sep 2017 06:43:37 GMT):
Right, I already tried hitting that API with PostMan e.g. https://10.*.*.*:7050/chaincode with required POST body but it does not work

sk (Fri, 22 Sep 2017 06:55:14 GMT):
Also will try with https://fabric-sdk-node.github.io/ - (is this SDK are you referring, right?)

there're several sdks in diff languages, feel free to pick one u prefer, good luck :)

rjones (Thu, 05 Oct 2017 06:35:18 GMT):
@baohua @david_dornseifer I fixed the issue. The build failure in 14177 is real: trailing whitespace

baohua (Thu, 05 Oct 2017 06:36:04 GMT):
thanks for the confirmation @rjones, and i believe this will help use fix it soon @david_dornseifer :)

rjones (Thu, 05 Oct 2017 06:37:01 GMT):
the issue was the current version of Jenkins doesn't support the older version of Java we have baked in, so I need to build a new image to fix that. I have a workaround in place though :)

baohua (Thu, 05 Oct 2017 07:15:05 GMT):

@rexxie latest doc is at http://cello.readthedocs.io/en/latest/. if you have further question, pls send mail to mailto:hyperledger-cello@lists.hyperledger.org

baohua (Mon, 16 Oct 2017 08:49:37 GMT):
@rubi_1432 are u looking for sth like https://github.com/hyperledger/cello/tree/master/src/agent/ansible?

@baohua Yes. Actua

rubi_1432 (Mon, 16 Oct 2017 08:51:57 GMT):
@baohua Yes i am looking into it but i am confused as for how i should edit script files for physical servers.

i think @tongli could give some hints :)

besides, there's doc inside the path, does that help u?

rubi_1432 (Mon, 16 Oct 2017 08:53:56 GMT):
Yes it did. I was able to understand a lot but there are few core concepts that i have ambiguity about.

rubi_1432 (Mon, 16 Oct 2017 08:55:21 GMT):
@baohua I have contacted @tongli but i didn't reicevd any response for him when i told about that i have physical machines ready for deployment :sweat_smile:

Hi guys, I'm new to Cello and Fabric, so sorry if my questions are basic

bogdancioc (Fri, 20 Oct 2017 08:51:44 GMT):
I'm installing the cello master node on OSX, on my mac

bogdancioc (Fri, 20 Oct 2017 08:51:56 GMT):
I am able to start the localhost:8080 web interface

bogdancioc (Fri, 20 Oct 2017 08:52:13 GMT):

bogdancioc (Fri, 20 Oct 2017 08:52:34 GMT):
looking in the logs of the mongodb container

bogdancioc (Fri, 20 Oct 2017 08:52:40 GMT):
i get this message that

bogdancioc (Fri, 20 Oct 2017 09:02:05 GMT):
"chown: changing ownership of '/data/db': Operation not permitted"

bogdancioc (Fri, 20 Oct 2017 09:02:11 GMT):
any ideas?

bogdancioc (Fri, 20 Oct 2017 09:03:20 GMT):
I'm running Docker 17.09.0-ce-mac35 (19611) on OSX 10.12.6 (Sierra)

baohua (Fri, 20 Oct 2017 13:37:17 GMT):
aha

baohua (Fri, 20 Oct 2017 13:37:33 GMT):
When using Cello on MacOS, the mongodb container may fail to start. This is because the container will try to mount `/opt/cello/mongo` path. To resolve the problem, users need to add `/opt/cello` to Docker's sharing path.

bogdancioc (Fri, 20 Oct 2017 13:53:27 GMT):
Hi baohua, I added /opt/cell/mongo to the list of local directories that can be mounted from within Docker

bogdancioc (Fri, 20 Oct 2017 13:53:38 GMT):
the container starts succesfully

bogdancioc (Fri, 20 Oct 2017 13:54:42 GMT):
and then throws a whole lot of "chown: changing ownership of '/data/db': Operation not permitted" in the log

bogdancioc (Fri, 20 Oct 2017 13:59:13 GMT):
what I can see is that the mongo container is trying to use two volumes: /data/configdb and /data/db

bogdancioc (Fri, 20 Oct 2017 15:57:30 GMT):
I think this line in the /cello/scripts/master_node/setup.sh might be the problem:

bogdancioc (Fri, 20 Oct 2017 15:57:32 GMT):
echo_b "Add existing user to docker group" sudo usermod -aG docker ${USER}

bogdancioc (Fri, 20 Oct 2017 15:57:42 GMT):
usermod doesn't work on OSX

bogdancioc (Fri, 20 Oct 2017 15:57:55 GMT):
any idea what I could replace it with?

bogdancioc (Fri, 20 Oct 2017 17:02:14 GMT):
I replaced the above line with this, and it worked

bogdancioc (Fri, 20 Oct 2017 17:02:15 GMT):
sudo dseditgroup -o edit -a ${USER} -t user staff

bogdancioc (Fri, 20 Oct 2017 17:02:41 GMT):
Can any of you guys tell me if this wrong or not?

bogdancioc (Fri, 20 Oct 2017 17:02:53 GMT):

bogdancioc (Fri, 20 Oct 2017 18:38:37 GMT):

bogdancioc (Fri, 20 Oct 2017 20:31:13 GMT):
perhaps the problem is Docker version 17.09.0-ce, build afdb6d4 ???

baohua (Fri, 20 Oct 2017 23:57:05 GMT):
@bogdancioc we do not have much doc on using cello on mac... would appreciate if you wanna add some. And can u connect to ur worker api from master? `sudo docker -H 192.168.x.xxx:2375 info` return success?

Yixing (Sat, 21 Oct 2017 04:00:46 GMT):
@bogdancioc by default Docker 17.09 will not listen on port 2375, you should specify the port when start docker daemon.

worker nodes can be some virtual server and combine as a single infrastructure pool, as a Host in Cello.

yes, mohammad

cello support multiple underly infrastructures like swarm, k8s, which will support cross-host networking. on top of that, we can deploy fabric on diff servers.

sk (Wed, 25 Oct 2017 05:45:20 GMT):
I could successfully setup Cello, created host and created chain also (via web-dashboard). Now I want to deploy chaincode, execute queries through web services. How can I do this? I visited http://cello.readthedocs.io/en/latest/api/restserver_v2/ but it does not have that functionalities. Please help.

baohua (Wed, 25 Oct 2017 17:02:55 GMT):
@sk cello doesn't provide additional support on chaincode rather than fabric itself, hence just use the network as fabric suggest to.

baohua (Wed, 25 Oct 2017 17:02:55 GMT):
@sk Right now, cello doesn't provide additional support on chaincode rather than fabric itself, hence just use the network as fabric suggest to.

baohua (Wed, 25 Oct 2017 17:03:10 GMT):
e.g., can use the fabric-sdk to trigger txs to a network.

@baohua In worker installation on this guide http://hyperledger-cello.readthedocs.io/en/latest/installation_worker_docker/ first step is to install docker daemon . Does it mean to create swarm network between master and worker node? right?

MohammadObaid (Fri, 27 Oct 2017 18:45:06 GMT):
Hi @baohua Is there any tutorial or link available as how to add fabric as a chain in hyperledger-cello. I have ready fabric-sdk network including all images and other artifacts. Now how do I will add that into cello chain? Any little clue or assist will really help me a lot. :)

baohua (Fri, 27 Oct 2017 21:45:31 GMT):
aha, @MohammadObaid we do not support this feature, only way is that u create a fabric network through cello. if you wanna it, pls help open an jira task, thanks!

[ ](https://chat.hyperledger.org/channel/cello?msg=Pp9vxCjmYwf7pAB8K) @MohammadObaid What's your environment? Actually my Cello works without special error, except my Mongo service can not be initialized. I and not quite sure, what is the root cause of it. I don't have root account, but I can run sudo commands. I am using 17.09 ce, and I have a local Mongodb installed.

lclclc (Mon, 30 Oct 2017 02:13:11 GMT):
Can it relate to mongo conflict?

baohua (Mon, 30 Oct 2017 02:50:41 GMT):
@MohammadObaid cello doesn't add any limit to fabric operations like chaincode usage, just follow the steps in the fabric docs. http://hlf.readthedocs.io/en/latest/

MohammadObaid (Mon, 30 Oct 2017 04:50:40 GMT):

I dont think its a problem with a docker.

lclclc (Mon, 30 Oct 2017 05:18:42 GMT):
Actually this is should be random case of Mongo 3.x image, what I have done with Docker preference is what I googled and found.

lclclc (Mon, 30 Oct 2017 05:19:18 GMT):
I assume there is a real physical file system path the docker is trying to map, but it is denied.

lclclc (Mon, 30 Oct 2017 05:19:57 GMT):
I just can't know how to debug it. Because I am running Cello, not directly a mongo container.

Currently Cello support deploy Fabric 0.6 and Fabric 1.0 cluster. but the image tags used in the docker compose file are missing. For example : image: hyperledger/fabric-peer

Currently Cello support deploy Fabric 0.6 and Fabric 1.0 cluster. But the image tags used in the docker compose file are missing. For example : image: hyperledger/fabric-peer This will cause our work node can only run one version of facbric, Ideally the work node should be decouple with what is running on it. Is there any background that we don't specify the image tag in the docker compose file? I know that the chain-code image always use latest tag, is this the reason ?

The issue is That /opt/cello is not share by root account, even I turn on the file sharing according to others experience, I finally chmoded and chowned to fix it. The lesson I learn is, Kitematic does not have the magic as it appears.

random port?

baohua (Tue, 31 Oct 2017 02:04:29 GMT):
sorry, can u elaborate that?

baohua (Tue, 31 Oct 2017 02:06:51 GMT):
@lclclc in `scripts/master_node/setup.sh`, we have the code to check the path already.

lclclc (Tue, 31 Oct 2017 02:09:04 GMT):
Users need to use some tools to config Docker daemon to listen at network manually, e.g., to config Docker daemon to listen on `127.0.0.1:2375`,

I mean this is helpful

lclclc (Tue, 31 Oct 2017 02:09:54 GMT):

From 17.06 onwards our recommendation is to connect to the special Mac-only DNS name docker.for.mac.localhost which will resolve to the internal IP address used by the host.```

JoshuaRippon (Wed, 01 Nov 2017 15:05:26 GMT):
Hi @tongli . I would really like to run a Fabric network on multiple hosts. This is how I stumbled across Cello

JoshuaRippon (Wed, 01 Nov 2017 15:06:43 GMT):
Will following the process you linked allow me to do this?

tongli (Wed, 01 Nov 2017 15:09:13 GMT):
absolutely. the ansible agent was designed to support that natively. all-in-one is just a slight different configuration to allow people to get things up running very quickly when people do not have multiple nodes.

tongli (Wed, 01 Nov 2017 15:09:30 GMT):
see this doc. https://github.com/hyperledger/cello/blob/master/src/agent/ansible/vars/README.md

tongli (Wed, 01 Nov 2017 15:09:49 GMT):
and this doc. https://github.com/hyperledger/cello/blob/master/src/agent/ansible/README.md

tongli (Wed, 01 Nov 2017 15:10:32 GMT):
this doc explains a bit what all the configuration files mean https://github.com/hyperledger/cello/blob/master/src/agent/ansible/vars/README.md

tongli (Wed, 01 Nov 2017 15:10:49 GMT):
but you can always ask questions here on the ansible agent, I will be happy to help.

JoshuaRippon (Wed, 01 Nov 2017 15:11:39 GMT):
So I am currently using Docker, is ansible an alternative?

tongli (Wed, 01 Nov 2017 15:12:06 GMT):
no, ansible is just a tool to get things lay out on multiple machines.

tongli (Wed, 01 Nov 2017 15:12:16 GMT):
you will be still using docker.

tongli (Wed, 01 Nov 2017 15:12:46 GMT):
docker is your container engine. ansible is just a tool to place and configure things at right place.

tongli (Wed, 01 Nov 2017 15:13:46 GMT):
once your fabric network got setup, ansible is out of the way.

JoshuaRippon (Wed, 01 Nov 2017 15:26:45 GMT):
@tongli I have got up to the stage where I have to create runhosts.tpl

JoshuaRippon (Wed, 01 Nov 2017 15:26:59 GMT):
cloud ansible_host=127.0.0.1 ansible_python_interpreter=python $ip private_ip=$ip public_ip=$ip inter_name=fabric001 [allnodes] $ip [etcdnodes] $ip [builders] $ip

tongli (Wed, 01 Nov 2017 15:27:11 GMT):
yeah

tongli (Wed, 01 Nov 2017 15:27:23 GMT):
run the little script

tongli (Wed, 01 Nov 2017 15:27:45 GMT):
I think you need to go to directory ~/cello/src/agent/ansible to run the two commands.

JoshuaRippon (Wed, 01 Nov 2017 15:27:57 GMT):
but do I have to replace all the $ip

tongli (Wed, 01 Nov 2017 15:28:01 GMT):
the instruction needs to be a little more clear on changing the directory.

tongli (Wed, 01 Nov 2017 15:28:05 GMT):
yes.

tongli (Wed, 01 Nov 2017 15:28:12 GMT):
the little script does that for you.

tongli (Wed, 01 Nov 2017 15:29:02 GMT):
create that tpl file and run these two commands in ~/cello/src/agent/ansible directory

tongli (Wed, 01 Nov 2017 15:29:07 GMT):
```ipaddr=$(ip -4 addr show | awk -F '/' '/inet / {print $1}' | grep -v '127.0.0.1' | awk -F ' ' '{print $2;exit}') sed "s/\$ip/$ipaddr/g" run/runhosts.tpl > run/runhosts```

tongli (Wed, 01 Nov 2017 15:29:27 GMT):
that will produce a new file in run directory named runhosts

tongli (Wed, 01 Nov 2017 15:29:58 GMT):
if you replace the $ip manually, then you do not have to run the commands.

tongli (Wed, 01 Nov 2017 15:30:30 GMT):
also, I think that the instruction missed how to setup ssh key in .ssh/authorized_key

tongli (Wed, 01 Nov 2017 15:30:46 GMT):
if you do not have that, then you can not use ssh to connect, the process will fail.

tongli (Wed, 01 Nov 2017 15:30:57 GMT):
so you need to do that as well.

tongli (Wed, 01 Nov 2017 15:31:04 GMT):
here is the process.

tongli (Wed, 01 Nov 2017 15:31:30 GMT):
1. in your ~/.ssh directory , create a file named authorized_keys

tongli (Wed, 01 Nov 2017 15:31:47 GMT):
2. Place the content of ~/.ssh/fd.pub file in that file and save it.

tongli (Wed, 01 Nov 2017 15:33:28 GMT):
once you have done that before you start step 4, log out and log back in and make sure that you ssh-agent is running, then you can go on step 4.

tongli (Wed, 01 Nov 2017 15:33:42 GMT):
I will make the steps a bit more clear in next patch set.

tongli (Wed, 01 Nov 2017 15:34:38 GMT):
@baohua @hightall can one of you merge this? https://gerrit.hyperledger.org/r/#/c/14999/ thanks.

JoshuaRippon (Wed, 01 Nov 2017 15:35:49 GMT):
I already have an authorized_keys file. Is it ok to follow your first steps. Will it wipe important data?

tongli (Wed, 01 Nov 2017 15:36:02 GMT):
no.

tongli (Wed, 01 Nov 2017 15:36:28 GMT):
if you already have authorized_keys, then you just need to add the created fd.pub at the end of the file.

tongli (Wed, 01 Nov 2017 15:36:56 GMT):
or best yet, skip creating the new ssh key pair in step #1, just go ahead using your existing key.

tongli (Wed, 01 Nov 2017 15:37:16 GMT):
but you will have to change couple files in vars directory as the instruction stated.

tongli (Wed, 01 Nov 2017 15:37:47 GMT):
authorized_keys file simply have bunch of public keys, it is a text file, you can edit it.

tongli (Wed, 01 Nov 2017 15:38:02 GMT):
it would not mess up anything.

JoshuaRippon (Wed, 01 Nov 2017 15:38:06 GMT):
sweet

tongli (Wed, 01 Nov 2017 15:40:21 GMT):
@hightall thanks for merging the patch set, now we are supporting latest version of ansible and as old as 2.3.0.0

JoshuaRippon (Wed, 01 Nov 2017 15:46:55 GMT):
@tongli is it literally a copy/paste to the end of authorized_keys? or do I remove ssh-rsa before pasting?

JoshuaRippon (Wed, 01 Nov 2017 15:47:08 GMT):
sorry for these newb questions!

tongli (Wed, 01 Nov 2017 15:48:19 GMT):
@JoshuaRippon it is literally copy and paste to the end of the file. true statement.

tongli (Wed, 01 Nov 2017 15:48:33 GMT):
should be on its own line.

tongli (Wed, 01 Nov 2017 15:48:47 GMT):
each public key should occupy one line.

tongli (Wed, 01 Nov 2017 15:49:05 GMT):
I suspect that you have quite few keys already there.

tongli (Wed, 01 Nov 2017 15:49:16 GMT):
and I hope this is a ubuntu 16.04 system.

tongli (Wed, 01 Nov 2017 15:49:31 GMT):
if you are using different OS, your miles will be probably very different.

tongli (Wed, 01 Nov 2017 15:49:43 GMT):
may not even work.

JoshuaRippon (Wed, 01 Nov 2017 15:51:02 GMT):
yes ubuntu 16.04

tongli (Wed, 01 Nov 2017 15:51:38 GMT):
k.

JoshuaRippon (Wed, 01 Nov 2017 15:56:22 GMT):
when running `-i run/runhosts -e "mode=apply env=vb" initcluster.yml --skip-tags="resetconn"` I get error `ERROR! Unexpected Exception: 'module' object has no attribute 'SSL_ST_INIT'`

JoshuaRippon (Wed, 01 Nov 2017 15:56:42 GMT):
Is this to do with using a different userID?

kayadhami (Wed, 01 Nov 2017 15:58:55 GMT):
Has joined the channel.

tongli (Wed, 01 Nov 2017 16:01:46 GMT):
hmmm.

tongli (Wed, 01 Nov 2017 16:02:04 GMT):
do you have ssh-agent running? in step #1

JoshuaRippon (Wed, 01 Nov 2017 16:04:24 GMT):
I ran `eval $(ssh-agent -s)` and got `Agent pid 94714`

tongli (Wed, 01 Nov 2017 16:04:51 GMT):
```eval $(ssh-agent -s) && ssh-add ~/.ssh/fd```

tongli (Wed, 01 Nov 2017 16:05:06 GMT):
do not miss the second part.

JoshuaRippon (Wed, 01 Nov 2017 16:05:52 GMT):
Yes I did that

JoshuaRippon (Wed, 01 Nov 2017 16:06:00 GMT):
still same error

tongli (Wed, 01 Nov 2017 16:06:57 GMT):
hmmm. the full error log?

tongli (Wed, 01 Nov 2017 16:07:33 GMT):
did you change the authorized_keys file?

tongli (Wed, 01 Nov 2017 16:07:44 GMT):
if you did, you will have to log out and log back in.

JoshuaRippon (Wed, 01 Nov 2017 16:08:59 GMT):
Just logged out and in again

tongli (Wed, 01 Nov 2017 16:09:01 GMT):
if you did not, and use your own key, then you will need to change vars/vb.yml file.

JoshuaRippon (Wed, 01 Nov 2017 16:09:02 GMT):
still same error

tongli (Wed, 01 Nov 2017 16:09:27 GMT):
when you log back in, you need to do this again

tongli (Wed, 01 Nov 2017 16:09:32 GMT):
```eval $(ssh-agent -s) && ssh-add ~/.ssh/fd```

JoshuaRippon (Wed, 01 Nov 2017 16:10:41 GMT):
did that, same error....

tongli (Wed, 01 Nov 2017 16:11:29 GMT):
ok. what is the full error msg?

tongli (Wed, 01 Nov 2017 16:12:25 GMT):
and , if your userid is not ubuntu, you need to change vars/vb.yml file as well.

JoshuaRippon (Wed, 01 Nov 2017 16:13:01 GMT):

tongli (Wed, 01 Nov 2017 16:13:50 GMT):
hmm. I wonder if your ansible version is not correct.

tongli (Wed, 01 Nov 2017 16:13:55 GMT):
do this command.

tongli (Wed, 01 Nov 2017 16:14:03 GMT):
```ansible --version```

JoshuaRippon (Wed, 01 Nov 2017 16:14:40 GMT):
ansible 2.3.0.0 config file = configured module search path = Default w/o overrides python version = 2.7.12 (default, Nov 19 2016, 06:48:10) [GCC 5.4.0 20160609]

tongli (Wed, 01 Nov 2017 16:14:55 GMT):
hmmm. that looks ok to me.

tongli (Wed, 01 Nov 2017 16:15:16 GMT):
you did this as well I assume ```sudo apt-get install python-dev python-pip libssl-dev libffi-dev -y```

JoshuaRippon (Wed, 01 Nov 2017 16:15:20 GMT):
my usierid is ubuntu

JoshuaRippon (Wed, 01 Nov 2017 16:15:53 GMT):
yes

tongli (Wed, 01 Nov 2017 16:16:56 GMT):
hmmm. looks like that you pyOpenSSL may be old. I am not sure. let me check few things

tongli (Wed, 01 Nov 2017 16:18:49 GMT):
do the following

tongli (Wed, 01 Nov 2017 16:19:25 GMT):
run the following command to check your pyOpenSSL

tongli (Wed, 01 Nov 2017 16:19:28 GMT):
python

tongli (Wed, 01 Nov 2017 16:19:33 GMT):
import OpenSSL

tongli (Wed, 01 Nov 2017 16:19:39 GMT):
OpenSSL.__version__

tongli (Wed, 01 Nov 2017 16:19:45 GMT):
this should give you a number.

tongli (Wed, 01 Nov 2017 16:19:56 GMT):
mine is 16.0.0 which worked fine.

tongli (Wed, 01 Nov 2017 16:22:03 GMT):
The error is reported here. https://github.com/MobSF/Mobile-Security-Framework-MobSF/issues/293

JoshuaRippon (Wed, 01 Nov 2017 16:22:04 GMT):
when I do `import OpenSSL` I get `'module' object has no attribute 'SSL_ST_INIT'`

tongli (Wed, 01 Nov 2017 16:22:26 GMT):
hmmm. you can not even do that in the python prompt?

JoshuaRippon (Wed, 01 Nov 2017 16:22:33 GMT):
correct

tongli (Wed, 01 Nov 2017 16:22:58 GMT):
hmm, your environment is having some issues.

tongli (Wed, 01 Nov 2017 16:25:01 GMT):
maybe try this command

tongli (Wed, 01 Nov 2017 16:25:05 GMT):
```sudo pip install pyOpenSSL --upgrade```

tongli (Wed, 01 Nov 2017 16:25:49 GMT):
or this

tongli (Wed, 01 Nov 2017 16:25:53 GMT):
```sudo pip install pyOpenSSL==16.0.0```

tongli (Wed, 01 Nov 2017 16:26:05 GMT):
this should upgrade you to a version which I know works.

tongli (Wed, 01 Nov 2017 16:26:19 GMT):
if you can not even do these things, then I am really running out of ideas.

tongli (Wed, 01 Nov 2017 16:26:36 GMT):
normally, I would recommend using a clean ubuntu 16.04 system.

tongli (Wed, 01 Nov 2017 16:27:06 GMT):
if your system can not do a simple python import, then something is really wrong.

JoshuaRippon (Wed, 01 Nov 2017 16:28:07 GMT):
it looks like my pip install isn't working properly

JoshuaRippon (Wed, 01 Nov 2017 16:28:21 GMT):
any time I try to pip install something I get the same error

JoshuaRippon (Wed, 01 Nov 2017 16:28:41 GMT):
should I try to reinstall pip

JoshuaRippon (Wed, 01 Nov 2017 16:28:44 GMT):
?

tongli (Wed, 01 Nov 2017 16:29:22 GMT):
did you try this?

tongli (Wed, 01 Nov 2017 16:29:25 GMT):
```sudo apt-get install python-dev python-pip```

tongli (Wed, 01 Nov 2017 16:29:54 GMT):
after that, do this

tongli (Wed, 01 Nov 2017 16:30:12 GMT):
``` sudo pip install pip --upgrade```, hope that fixes your issue.

JoshuaRippon (Wed, 01 Nov 2017 16:31:12 GMT):
didn't work unfortunately

tongli (Wed, 01 Nov 2017 16:34:01 GMT):
your python env is not doing well.

JoshuaRippon (Wed, 01 Nov 2017 16:34:17 GMT):
hahaha

tongli (Wed, 01 Nov 2017 16:34:18 GMT):
probably fix your python issue.

tongli (Wed, 01 Nov 2017 16:34:26 GMT):
first.

tongli (Wed, 01 Nov 2017 16:34:54 GMT):
I would suggest to have a relatively clean system for this.

JoshuaRippon (Wed, 01 Nov 2017 16:49:12 GMT):
@tongli I removed OpenSSL and reinstalled it

JoshuaRippon (Wed, 01 Nov 2017 16:49:30 GMT):
not getting that error any more!

JoshuaRippon (Wed, 01 Nov 2017 17:08:58 GMT):
I ran `ansible-playbook -i run/runhosts -e "mode=apply env=vb" initcluster.yml --skip-tags="resetconn"` which was fine

JoshuaRippon (Wed, 01 Nov 2017 17:10:09 GMT):
However when I run `ansible-playbook -i run/runhosts -e "mode=apply env=bc2nd" setupfabric.yml` I get the error ```TASK [Make targets] ************************************************************************************************************************************************************************************************************************* changed: [10.0.4.7] => (item=cryptogen) failed: [10.0.4.7] (item=configtxgen) => {"changed": true, "cmd": "make configtxgen >> /opt/gopath/bc2nd/build.log", "delta": "0:00:01.466978", "end": "2017-11-01 17:08:17.536043", "failed": true, "item": "configtxgen", "rc": 2, "start": "2017-11-01 17:08:16.069065", "stderr": "go install vendor/golang_org/x/crypto/chacha20poly1305: open /opt/go/pkg/linux_amd64/vendor/golang_org/x/crypto/chacha20poly1305.a: permission denied\nmake: *** [build/bin/configtxgen] Error 1", "stderr_lines": ["go install vendor/golang_org/x/crypto/chacha20poly1305: open /opt/go/pkg/linux_amd64/vendor/golang_org/x/crypto/chacha20poly1305.a: permission denied", "make: *** [build/bin/configtxgen] Error 1"], "stdout": "", "stdout_lines": []} to retry, use: --limit @/home/ubuntu/hyperledger/cello/src/agent/ansible/setupfabric.retry```

tongli (Wed, 01 Nov 2017 17:30:04 GMT):
hmmm. @JoshuaRippon seems that you can not run make to build the cryptogen.

JoshuaRippon (Wed, 01 Nov 2017 17:31:02 GMT):
Hmm why might that be?

tongli (Wed, 01 Nov 2017 17:31:35 GMT):
can your user ubuntu do this?

tongli (Wed, 01 Nov 2017 17:31:42 GMT):
```sudo su```

JoshuaRippon (Wed, 01 Nov 2017 17:32:06 GMT):
yup

tongli (Wed, 01 Nov 2017 17:32:08 GMT):
without promote password, actually, that might not be the problem.

tongli (Wed, 01 Nov 2017 17:32:49 GMT):
you may try to go to fabric directory, and run make configtxgen and see what happens.

tongli (Wed, 01 Nov 2017 17:34:24 GMT):
can you check who owns this directory?

JoshuaRippon (Wed, 01 Nov 2017 17:34:50 GMT):
`make: Nothing to be done for 'configtxgen'`

tongli (Wed, 01 Nov 2017 17:34:51 GMT):
can you check who owns this direct /opt/go/pkg

tongli (Wed, 01 Nov 2017 17:37:06 GMT):
hmm, you should have a directory like this /opt/gopath/bc2nd/src/github.com/hyperledger/fabric

tongli (Wed, 01 Nov 2017 17:37:21 GMT):
did you see a directory like that on your system?

JoshuaRippon (Wed, 01 Nov 2017 17:37:41 GMT):
It is owned by root

tongli (Wed, 01 Nov 2017 17:38:11 GMT):
then there should be build/bin, in that directory, you should have configtxgen amd cryptogen

tongli (Wed, 01 Nov 2017 17:38:17 GMT):
which should be just built.

JoshuaRippon (Wed, 01 Nov 2017 17:38:20 GMT):
yes I have that

tongli (Wed, 01 Nov 2017 17:39:16 GMT):
even configtxgen?

tongli (Wed, 01 Nov 2017 17:39:22 GMT):
but it said that it failed

JoshuaRippon (Wed, 01 Nov 2017 17:39:39 GMT):
it has cryptogen but not configtxgen in it

tongli (Wed, 01 Nov 2017 17:39:56 GMT):
right.

JoshuaRippon (Wed, 01 Nov 2017 17:40:09 GMT):
it only has cryptogen, no other files

tongli (Wed, 01 Nov 2017 17:40:36 GMT):
can you try ```make configtxgen``` in this directory /opt/gopath/bc2nd/src/github.com/hyperledger/fabric

JoshuaRippon (Wed, 01 Nov 2017 17:41:24 GMT):

tongli (Wed, 01 Nov 2017 17:41:48 GMT):
yeah, seems same error.

tongli (Wed, 01 Nov 2017 17:41:55 GMT):
check your env varilable

tongli (Wed, 01 Nov 2017 17:42:03 GMT):
```echo $GOROOT```

tongli (Wed, 01 Nov 2017 17:42:11 GMT):
```echo $GOPATH```

JoshuaRippon (Wed, 01 Nov 2017 17:42:26 GMT):
nothing in either

tongli (Wed, 01 Nov 2017 17:42:42 GMT):
hmmm.

tongli (Wed, 01 Nov 2017 17:42:44 GMT):
do this.

tongli (Wed, 01 Nov 2017 17:42:54 GMT):
export GOPATH=/opt/gopath

tongli (Wed, 01 Nov 2017 17:43:00 GMT):
export GOROOT=/opt/go

JoshuaRippon (Wed, 01 Nov 2017 17:43:37 GMT):
Ok done

JoshuaRippon (Wed, 01 Nov 2017 17:45:21 GMT):
I have the configtxgen file but not in this directory

JoshuaRippon (Wed, 01 Nov 2017 17:45:35 GMT):
should I just copy it over?

tongli (Wed, 01 Nov 2017 17:46:11 GMT):
no, it won't help

tongli (Wed, 01 Nov 2017 17:46:28 GMT):
you have go installed in different directory, that messed up the go build.

JoshuaRippon (Wed, 01 Nov 2017 17:49:00 GMT):
I installed go for go-ipfs a while back

tongli (Wed, 01 Nov 2017 17:49:19 GMT):
sigh! yeah. a lot of conflict.

tongli (Wed, 01 Nov 2017 17:49:28 GMT):
these kind of problems are hard to fix.

JoshuaRippon (Wed, 01 Nov 2017 17:50:03 GMT):
I have a different server, maybe I will try launch it on that one!!

tongli (Wed, 01 Nov 2017 17:50:29 GMT):
make sure it is really clean.

tongli (Wed, 01 Nov 2017 17:50:42 GMT):
no go installed.

tongli (Wed, 01 Nov 2017 17:50:53 GMT):
you can install docker if you want to.

tongli (Wed, 01 Nov 2017 17:51:10 GMT):
before you do anything on that machine, you can simply do this one thing.

tongli (Wed, 01 Nov 2017 17:51:21 GMT):
```apt update```

tongli (Wed, 01 Nov 2017 17:51:30 GMT):
```apt install docker.io```

tongli (Wed, 01 Nov 2017 17:51:36 GMT):
this will help

JoshuaRippon (Wed, 01 Nov 2017 17:51:44 GMT):
So I guess I should find out what the end result will be once I have it up and running. Will I be able to simply edit that runhosts file to add multiple hosts to the network

tongli (Wed, 01 Nov 2017 17:51:44 GMT):
make sure that go lang is not on it.

tongli (Wed, 01 Nov 2017 17:52:00 GMT):
exactly.

tongli (Wed, 01 Nov 2017 17:52:34 GMT):
runhosts is considered as a configuration file.

JoshuaRippon (Wed, 01 Nov 2017 17:53:05 GMT):
Damn I have Go on this one too haha

tongli (Wed, 01 Nov 2017 17:53:12 GMT):
you will also need to change couple of other files in vars directory to make it working.

tongli (Wed, 01 Nov 2017 17:53:24 GMT):
for multiple nodes.

tongli (Wed, 01 Nov 2017 17:53:34 GMT):
can you remove it before you go on?

tongli (Wed, 01 Nov 2017 17:53:50 GMT):
I normally just install VirtualBox and have a VM running on VirtualBox.

Hi @tongli I read your conversation with @JoshuaRippon I too am trying to run nodes on different hosts. But this is only for the Hyperledger Marbles demo. The idea is to make sure if one host fails, the blockchain is not affected as there are supporting nodes on n number of hosts. I have installed Cello on one host(a) and the marbles demo on another host(b). I am trying to add the marbles host(b) to cello host(a) with docker port 2375 Is this the way to do it? Could I add more nodes on other hosts(c&d) ? Thanks

tongli (Thu, 02 Nov 2017 18:33:03 GMT):
@ajksharma actually I am not really sure. I think the way you use cello is different from what the ansible agent does.

tongli (Thu, 02 Nov 2017 18:33:24 GMT):
@ajksharma cello ansible agent sets up multiple node fabric network in one go.

tongli (Thu, 02 Nov 2017 18:33:36 GMT):
regardless it is 3 nodes or 300 nodes.

tongli (Thu, 02 Nov 2017 18:34:17 GMT):
currently the agent can not add new nodes after initial fabric network started running. we need to add that function.

tongli (Thu, 02 Nov 2017 18:34:59 GMT):
with multiple nodes in fabric network, multiple peers, orderers, one peer goes down should not affect the availability of your fabric network.

tongli (Thu, 02 Nov 2017 18:36:31 GMT):
btw, ansible agent uses kafka for orderers.

tongli (Thu, 02 Nov 2017 18:36:45 GMT):
kafka and zookeeper be exact.

ajksharma (Thu, 02 Nov 2017 18:39:06 GMT):
Thanks @tongli . So in one go I can add n numbers of nodes on n number of hosts? I have 5 hosts with me. Marbles demo is working fine on one host. If i can't add more nodes, can I run the ansible script with marbles somehow and create this multi-node setup? Question is , can the marbles demo be run on multiple nodes on multiple hosts? Its on github and easy to setup on one host.

tongli (Thu, 02 Nov 2017 18:40:04 GMT):
@ajksharma ansible agent can not add nodes to an existing fabric network.

tongli (Thu, 02 Nov 2017 18:40:25 GMT):
it stands up multiple node fabric network.

ajksharma (Thu, 02 Nov 2017 18:40:41 GMT):
I understand that. I am ready to run on a clean state

tongli (Thu, 02 Nov 2017 18:41:42 GMT):
right. in that case, say you have 5 machines, you can use cello to stand up a 5 node fabric network with multiple orgs, multiple peers and orderers in each org.

tongli (Thu, 02 Nov 2017 18:42:23 GMT):
the easiest to do this if you have AWS account, you can use cello against AWS cloud.

tongli (Thu, 02 Nov 2017 18:42:55 GMT):
cello will do provisioning of VMs, establish secuirty rules, and eventually get your 5 node fabric network up running.

ajksharma (Thu, 02 Nov 2017 18:43:07 GMT):
yes, I have an aws account and have 5 hosts already made.

ajksharma (Thu, 02 Nov 2017 18:43:28 GMT):
So cello would spine "new" VMs?

tongli (Thu, 02 Nov 2017 18:43:31 GMT):
https://github.com/hyperledger/cello/tree/master/src/agent/ansible

tongli (Thu, 02 Nov 2017 18:43:52 GMT):
yes, Cello will spin up new VMs.

tongli (Thu, 02 Nov 2017 18:44:41 GMT):
```1. make changes to vars/aws.yml according to your aws cloud 2. export AWS_SECRET_KEY="your secret key of your aws account" 3. To stand up the fabric network:: ansible-playbook -e "mode=apply" aws.yml 4. To tear down the fabric network:: ansible-playbook -e "mode=destroy" aws.yml```

tongli (Thu, 02 Nov 2017 18:45:40 GMT):
if you have a aws account, and allow you to create new VMs, then you can run cello ansible agent from your own laptop.

tongli (Thu, 02 Nov 2017 18:46:09 GMT):
your own laptop will serve as an ansible controller.

tongli (Thu, 02 Nov 2017 18:47:40 GMT):
@ajksharma please also look at this doc which deals with aws cloud. https://github.com/hyperledger/cello/tree/master/src/agent/ansible/roles/cloud_aws

tongli (Thu, 02 Nov 2017 18:48:26 GMT):
ansible aws cloud module requires boto and boto3, please install using this command before you run

tongli (Thu, 02 Nov 2017 18:48:38 GMT):
```sudo pip install boto boto3```

tongli (Thu, 02 Nov 2017 18:48:50 GMT):
that is only required on your ansible controller.

tongli (Thu, 02 Nov 2017 18:49:26 GMT):
where you actually run the ansible command, it is not needed on actual AWS VMs

ajksharma (Thu, 02 Nov 2017 18:49:52 GMT):
great, i would try that @tongli Once I set that up, how do I up the marbles demo https://github.com/IBM-Blockchain/marbles on this network? Can I use an

tongli (Thu, 02 Nov 2017 18:50:12 GMT):
ansible agent does not setup any apps.

tongli (Thu, 02 Nov 2017 18:50:39 GMT):
I would suggest that you pick one of your AWS VMs and get your actual app up running.

tongli (Thu, 02 Nov 2017 18:51:39 GMT):
I will be really happy to see a patch to cello ansible agent for deploying marble app on top of the fabric network which cello ansible agent sets up.

ajksharma (Thu, 02 Nov 2017 18:52:16 GMT):
yep, I would select one VM and install marbles.

tongli (Thu, 02 Nov 2017 18:52:42 GMT):
right. these VMs will have a local DNS services setup.

ajksharma (Thu, 02 Nov 2017 18:52:53 GMT):
but then do I have to install marbles on all VMs?

tongli (Thu, 02 Nov 2017 18:52:56 GMT):
you will be able to refer their dns name for access.

tongli (Thu, 02 Nov 2017 18:53:23 GMT):
that I do not know. I would assume no. your app just need to access a fabric network.

tongli (Thu, 02 Nov 2017 18:54:07 GMT):
should not matter how big the fabric network is or if runs cross multiple nodes.

ajksharma (Thu, 02 Nov 2017 18:54:10 GMT):
yes, If I could n number of nodes working for the marbles demo, that is teh goal.

tongli (Thu, 02 Nov 2017 18:54:52 GMT):
I would think it depends how marbles demo were setup. can marbles demo app be spread out to multiple nodes?

tongli (Thu, 02 Nov 2017 18:55:20 GMT):
it should not have anything to do with how fabric network gets setup or how many nodes.

ajksharma (Thu, 02 Nov 2017 18:56:09 GMT):
I don't know. But I hope it doesn't matter.

ajksharma (Thu, 02 Nov 2017 18:56:31 GMT):
The chain-code would be one one VM.

tongli (Thu, 02 Nov 2017 18:57:03 GMT):
chaincode can be installed on many peers.

ajksharma (Thu, 02 Nov 2017 18:57:53 GMT):
if chaincode is absent on other hosts, the blockchain wouldn't run? right?

tongli (Thu, 02 Nov 2017 18:58:59 GMT):
I think it is per peer, not host

tongli (Thu, 02 Nov 2017 18:59:10 GMT):
one host can run multiple peers.

ajksharma (Thu, 02 Nov 2017 19:00:49 GMT):
yep, so maybe install the chaincode on all peers. I read on my post that docker swarm works. Though I am not sure how to add more nodes to the fabric network

ajksharma (Thu, 02 Nov 2017 19:00:49 GMT):

ajksharma (Thu, 02 Nov 2017 19:10:38 GMT):
@tongli though I know golang and was thinking that by now (3 weeks) I would be able to design and code hyperledger networks, I am still stuck in configuration issues. What is a good resource or is there a way that this environment becomes easy to handle and with a little hard work, bottle necks could be overcome? Do I need to see the guts of the system to understand more?

tongli (Thu, 02 Nov 2017 19:24:17 GMT):
@ajksharma are you asking how you can get a deep understanding of fabric?

ajksharma (Thu, 02 Nov 2017 19:25:24 GMT):
yes, I get stuck all the time and lack of knowledge of Hyperledger Fabric internal may be the reason. Though I am not sure.

ajksharma (Thu, 02 Nov 2017 19:25:24 GMT):

MohammadObaid (Sat, 04 Nov 2017 07:55:58 GMT):
It may be due to low memory. While configuring ansible on aws file I decided to give `t2.micro` instead of `t2.medium` beacuse of free tier I am using. On kafka logs I got an error `OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)`

tongli (Mon, 06 Nov 2017 17:08:01 GMT):
@rubi_1432 how did you set up these 3 machines? they need to have the ssh public key on each machine in ~/.ssh/authorized_keys file.

tongli (Mon, 06 Nov 2017 17:08:15 GMT):
without the file, you can not access them.

tongli (Mon, 06 Nov 2017 17:08:35 GMT):
I mean that ansible can not access them using key paires

MohammadObaid (Mon, 06 Nov 2017 17:23:37 GMT):
@tongli without kafka channels and chaincode wont be initialized properly . Am I right?

tongli (Mon, 06 Nov 2017 17:24:55 GMT):
kafka(solo) is to allow orderers to work correctly, without either, orderers can not work and channels can not be created.

tongli (Mon, 06 Nov 2017 17:41:33 GMT):
@MohammadObaid the last two containers actually are what magic happens.

tongli (Mon, 06 Nov 2017 17:41:50 GMT):
for containers to communicate with each other using names, we need registrators and dns services.

tongli (Mon, 06 Nov 2017 17:43:02 GMT):
each node will have a registrator container and entire fabric network will have one dns services.

tongli (Mon, 06 Nov 2017 17:43:10 GMT):
dns service container.

tongli (Mon, 06 Nov 2017 17:44:08 GMT):
this way, all containers will be able to simply use their names to address each other, other than IP addresses , in many cases IP addresses are unknown before fabric network is up running. but names are known.

MohammadObaid (Mon, 06 Nov 2017 17:59:07 GMT):
and fabric001 will be consider as dns service container as mentioned in aws.yml file `builders: ["fabric001"]` right?

tongli (Mon, 06 Nov 2017 18:01:24 GMT):
skydns.fabric001 is the dns container

tongli (Mon, 06 Nov 2017 18:01:32 GMT):
it runs on fabric001 node.

tongli (Mon, 06 Nov 2017 18:01:47 GMT):
this should be the only container for dns service for your entire fabric network.

MohammadObaid (Mon, 06 Nov 2017 18:05:53 GMT):
Alright . Thanks for detailed info :)

tongli (Mon, 06 Nov 2017 18:25:33 GMT):
@MohammadObaid from your image posted above, it does not look like your network is running, the kafka container is not doing well.

MohammadObaid (Tue, 07 Nov 2017 09:36:49 GMT):
@tongli Yeah you are right. Basically in my aws.yml file I change this `flavor_name: "t2.medium"` to `flavor_name: "t2.micro"` which causes kafka container to break because kafka required 1 GB RAM and t2.micro dosent provide enough to run kafka properly

rubi_1432 (Tue, 07 Nov 2017 10:38:49 GMT):
@tongli I have three physical machines. With hostname fabirc001, fabric002 and fabirc003. I installed openssh-server on fabric002 and fabric003. Then i used made sure that every user was able to use *sudo su* without password. Then on fabric001 i executed these commands *mkdir -p ~/.ssh && cd ~/.ssh && ssh-keygen -t rsa -f fd -P "" eval $(ssh-agent -s) && ssh-add ~/.ssh/fd* After thiso made sure that they are able to ping eachother and then i executed following command from fabric001 *cat ~/.ssh/fd.pub | ssh fabric002 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"* *cat ~/.ssh/fd.pub | ssh fabric003 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"*

tongli (Tue, 07 Nov 2017 14:34:43 GMT):
@rubi_1432 it seems to me that you are using fabric001 also as your ansible controller, is that right?

tongli (Tue, 07 Nov 2017 14:35:20 GMT):
the step you referenced above only is needed where you run the ansible project.

tongli (Tue, 07 Nov 2017 14:36:14 GMT):
the fd.pub file will need to be on all the servers .ssh directory in file authorized_keys file.

tongli (Tue, 07 Nov 2017 14:37:01 GMT):
the private key only needs to be on the ansible controller (in your case, fabric001).

tongli (Tue, 07 Nov 2017 14:38:06 GMT):
looks like that your command above did that.

tongli (Tue, 07 Nov 2017 14:38:46 GMT):
if all the steps are correct, after you did this ``eval $(ssh-agent -s) && ssh-add ~/.ssh/fd```

tongli (Tue, 07 Nov 2017 14:39:15 GMT):
you should be able to simply do the following to hit fabric002 and fabric003.

tongli (Tue, 07 Nov 2017 14:39:35 GMT):
```ssh fabric002_ip``` from fabric001 machine.

tongli (Tue, 07 Nov 2017 14:39:48 GMT):
if you can not do that, then your setup has not been correct.

tongli (Tue, 07 Nov 2017 14:40:27 GMT):
good news is that if you are using cello ansible agent against a cloud like what @MohammadObaid has done, all these things will be done for you by the project.

tongli (Tue, 07 Nov 2017 14:40:42 GMT):
a cloud like AWS or OpenStack cloud

tongli (Tue, 07 Nov 2017 14:41:53 GMT):
all you have to do will be just change few things in vars/aws.yml file, and run one command to get things going. see things at this link. https://github.com/hyperledger/cello/tree/master/src/agent/ansible#on-aws-cloud

tongli (Tue, 07 Nov 2017 14:42:49 GMT):
when you have physical servers or Virtual Machines, it will be a bit tedious because ansible agent has to know where your servers are and how to access them.

tongli (Tue, 07 Nov 2017 14:43:54 GMT):
what you are trying to do in these manual steps are basically setting up ssh access so that your ssh client (which ansible depends on) can work with these machines.

tongli (Tue, 07 Nov 2017 14:44:32 GMT):
the reason that ansible was chosen is because when you have very large numbers of servers, ansible will still be able to handle them regardless you have one or 100.

tongli (Tue, 07 Nov 2017 14:44:47 GMT):
and the way to handle one or 100 is absolutely identical.

JoshuaRippon (Tue, 07 Nov 2017 15:02:58 GMT):
Hi @tongli I am going to try your method again with a fresh ubuntu server!!

JoshuaRippon (Tue, 07 Nov 2017 15:04:21 GMT):
I am confused at the point of the key pair. I think this time I should just keep the key pair that I already have and include it in the vars/vb.yml and vars/bc2nd.yml files

tongli (Tue, 07 Nov 2017 15:04:25 GMT):
@JoshuaRippon sure, sure, if I remember you are using one node , right?

JoshuaRippon (Tue, 07 Nov 2017 15:04:30 GMT):
yes

tongli (Tue, 07 Nov 2017 15:04:53 GMT):
if you like, I was trying to get the all-in-one doc improved so that it will be easier to follow.

tongli (Tue, 07 Nov 2017 15:05:07 GMT):
unfortnately it has not been merged but you can still follow it if you like.

tongli (Tue, 07 Nov 2017 15:05:10 GMT):
here it is https://gerrit.hyperledger.org/r/#/c/15133/3/src/agent/ansible/vars/All-in-one.md,unified

tongli (Tue, 07 Nov 2017 15:06:01 GMT):
crap, that link has older and newer version all merged together.

tongli (Tue, 07 Nov 2017 15:06:04 GMT):
not good.

tongli (Tue, 07 Nov 2017 15:06:18 GMT):
hold on, let me see if there is a way just to see the latest version.

JoshuaRippon (Tue, 07 Nov 2017 15:06:21 GMT):
haha

tongli (Tue, 07 Nov 2017 15:07:15 GMT):
this link is better https://gerrit.hyperledger.org/r/cat/15133%2C3%2Csrc/agent/ansible/vars/All-in-one.md%5E0

tongli (Tue, 07 Nov 2017 15:07:38 GMT):
I think that link let you see the only the new version.

tongli (Tue, 07 Nov 2017 15:08:00 GMT):
you can follow that. please make sure that your ubuntu system is clean.

tongli (Tue, 07 Nov 2017 15:08:32 GMT):
if it is polluted, you will have some strange issues which will be hard to figure out.

JoshuaRippon (Tue, 07 Nov 2017 15:08:47 GMT):
yes its completely clean

tongli (Tue, 07 Nov 2017 15:08:59 GMT):
I strongly suggest that you install VirtualBox on your laptop or desktop, then using it for the work.

tongli (Tue, 07 Nov 2017 15:09:14 GMT):
VirtualBox is free and will save you a lot of headaches down the road.

JoshuaRippon (Tue, 07 Nov 2017 15:10:06 GMT):
Ok

JoshuaRippon (Tue, 07 Nov 2017 15:10:56 GMT):
so this bit i am still really confused about. The key pair part. I already have a key pair. If I want to use that one instead, how do I include it in vars/vb.yml and vars/bc2nd.yml files

JoshuaRippon (Tue, 07 Nov 2017 15:10:59 GMT):
?

JoshuaRippon (Tue, 07 Nov 2017 15:12:35 GMT):
Where abouts do I put the key pair in here? ```--- # The url to the fabric source repository GIT_URL: "http://gerrit.hyperledger.org/r/fabric" # The gerrit patch set reference, should be automatically set by gerrit GERRIT_REFSPEC: "" # The following defines a fabric network with 2 peers, 1 orderer, 1 zookeeper and 1 kafka # It also defines that the peers will be using goleveldb. fabric: { ssh_user: "ubuntu", peer_db: "goleveldb", tls: true, network: { fabric001: { peers: ["leader@peer1st.mad","anchor@peer2nd.mad"], orderers: ["1storderer.sin"], zookeepers: ["zookeeper1st"], kafkas: ["kafka1st"] } }, baseimage_tag: "1.0.2", ca: { tag: "1.0.2", admin: "admin", adminpw: "adminpw" } } ```

tongli (Tue, 07 Nov 2017 16:11:04 GMT):
@JoshuaRippon you include the key pair in vars/vb.yml file.

tongli (Tue, 07 Nov 2017 16:11:32 GMT):
the vars/vb2nd.yml is the file to layout your fabric network topology.

JoshuaRippon (Tue, 07 Nov 2017 16:13:22 GMT):
Here is my vb.yml

JoshuaRippon (Tue, 07 Nov 2017 16:13:28 GMT):
``` --- auth: { # Define where the VirtualBox(VB) system is auth_url: "192.168.0.36", # User name to log in to the remote VB system username: "tongli", # Password to the VB system, can specify at command line # or use env variable named PASSWORD password: "{{ password | default(lookup('env', 'password')) }}" } # This variable defines cloud provision attributes cluster: { target_os: "ubuntu", image_name: "fabricbase", ssh_user: "ubuntu", ssh_pass: "ps", validate_certs: True, public_key_file: "/home/ubuntu/.ssh/fd.pub", private_key_file: "/home/ubuntu/.ssh/fd", # This variable indicate what IP should be used, only valid values are # private_ip or public_ip node_ip: "public_ip", container_network: { Network: "172.16.0.0/16", SubnetLen: 24, SubnetMin: "172.16.0.0", SubnetMax: "172.16.255.0", Backend: { Type: "udp", Port: 8285 } }, service_ip_range: "172.15.0.0/16", dns_service_ip: "172.15.0.4", # the section defines preallocated IP addresses for each node, if there is no # preallocated IPs, leave it blank node_ips: ["169.45.102.186", "169.45.102.187", "169.45.102.188"], # fabric network node names expect to be using a clear pattern, this defines # the prefix for the node names. name_prefix: "fabric", domain: "fabricnet", # stack_size determines how many virtual or physical machines we will have # each machine will be named ${name_prefix}001 to ${name_prefix}${stack_size} stack_size: 2, etcdnodes: ["fabric001"], builders: ["fabric001"], flannel_repo: "https://github.com/coreos/flannel/releases/download/v0.7.1/flannel-v0.7.1-linux-amd64.tar.gz", etcd_repo: "https://github.com/coreos/etcd/releases/download/v3.2.0/etcd-v3.2.0-linux-amd64.tar.gz", k8s_repo: "https://storage.googleapis.com/kubernetes-release/release/v1.7.0/bin/linux/amd64/", go_ver: "1.8.3", # If volume want to be used, specify a size in GB, make volume size 0 if wish # not to use volume from your cloud volume_size: 0, # cloud block device name presented on virtual machines. block_device_name: "/dev/vdb" } ```

JoshuaRippon (Tue, 07 Nov 2017 16:13:53 GMT):
what do I change here?

tongli (Tue, 07 Nov 2017 16:16:45 GMT):
you see the public key and private key?

tongli (Tue, 07 Nov 2017 16:17:09 GMT):
public_key_file, private_key_file,

tongli (Tue, 07 Nov 2017 16:17:28 GMT):
you change the value of these two things.

tongli (Tue, 07 Nov 2017 16:17:55 GMT):
but the important thing is that you have to put the public key in .ssh/authorized_keys file.

tongli (Tue, 07 Nov 2017 16:18:13 GMT):
otherwise, you can not ssh to this machine.

JoshuaRippon (Tue, 07 Nov 2017 16:19:52 GMT):
ok cool so can I just leave that file and just create fd.pub and fd with my keys?

JoshuaRippon (Tue, 07 Nov 2017 16:21:44 GMT):
Also Hyperledger Fabric requires Docker version 17.03.0-ce or greater

JoshuaRippon (Tue, 07 Nov 2017 16:23:01 GMT):
Will I run into problems as `sudo apt-get install docker.io` gives me `Docker version 1.12.6, build 78d1802`

tongli (Tue, 07 Nov 2017 16:37:20 GMT):
@JoshuaRippon I am not following, you can either use your own key pair or create brand new key pair.

tongli (Tue, 07 Nov 2017 16:37:33 GMT):
I do not know what you mean by create fd.pub and fd with my keys.

JoshuaRippon (Tue, 07 Nov 2017 16:38:51 GMT):
when i run ```mkdir -p ~/.ssh && cd ~/.ssh && ssh-keygen -t rsa -f fd -P "" eval $(ssh-agent -s) && ssh-add ~/.ssh/fd``` aren't I just creatin new keys

JoshuaRippon (Tue, 07 Nov 2017 16:39:22 GMT):
with public key in fd.pub and priv key in fd?

tongli (Tue, 07 Nov 2017 16:40:41 GMT):
right. that creates new key named fd.pub and fd

tongli (Tue, 07 Nov 2017 16:40:49 GMT):
one is private key and one is public key.

tongli (Tue, 07 Nov 2017 16:41:20 GMT):
to be able to allow ssh to a machine, you have to add the fd.pub content into this file ~/.ssh/authorized_keys

tongli (Tue, 07 Nov 2017 16:41:44 GMT):
it has nothing to do with whatever keys that you might already have.

tongli (Tue, 07 Nov 2017 16:42:03 GMT):
if your system is new, then you should not have any keys I would assume.

JoshuaRippon (Tue, 07 Nov 2017 16:43:12 GMT):
yes I have keys already set up

tongli (Tue, 07 Nov 2017 16:43:21 GMT):
k.

tongli (Tue, 07 Nov 2017 16:43:35 GMT):
before you do anything, you can verify if you can actually ssh to this server.

tongli (Tue, 07 Nov 2017 16:43:49 GMT):
simply do ssh ubuntu@theIPaddress.

tongli (Tue, 07 Nov 2017 16:43:59 GMT):
or the userid that you have.

tongli (Tue, 07 Nov 2017 16:44:10 GMT):
I use ubuntu as an example.

tongli (Tue, 07 Nov 2017 16:44:31 GMT):
notice that vars/vb.yml file also has ssh_user, make sure that is also changed,

tongli (Tue, 07 Nov 2017 16:44:38 GMT):
to match whtever you have.

tongli (Tue, 07 Nov 2017 16:44:51 GMT):
without changing that to what you have, ssh will also fail.

JoshuaRippon (Tue, 07 Nov 2017 16:45:50 GMT):
Haha you know what I'll leave it till tomorrow when my colleague is in. He sets up all the servers so will know about this stuff way more than me! My background is physics! lol

tongli (Tue, 07 Nov 2017 16:47:46 GMT):
@JoshuaRippon good try though.

JoshuaRippon (Tue, 07 Nov 2017 16:48:01 GMT):
cheers!

JoshuaRippon (Tue, 07 Nov 2017 16:50:04 GMT):
Just quickly though, will I run into problems connecting to Fabric as fabric requires Docker version 17.03.0-ce or greater?

tongli (Tue, 07 Nov 2017 16:51:18 GMT):
the process will install the right version of golang and docker on this clean system.

tongli (Tue, 07 Nov 2017 16:51:25 GMT):
it will be all taken care of for you.

tongli (Tue, 07 Nov 2017 16:51:29 GMT):
Go Cello.

tongli (Tue, 07 Nov 2017 16:51:51 GMT):
that is the reason why keep saying clean clean clean system.

harsha (Fri, 10 Nov 2017 04:23:18 GMT):
And why do we use `cello-user-dashboard` ?

Hi. I have just updated my master node setup, and when i start it I get the following top-level error inside restserver: ```File "/app/agent/vsphere/host_operations.py", line 13, in from pyVmomi import vim ImportError: No module named 'pyVmomi'``` What should I do to make it work?

Hansuuuuuuuuuu (Sat, 11 Nov 2017 04:49:50 GMT):

@baohua hope that you've had a great meeting in Singapore. I added two patch set.

tongli (Mon, 13 Nov 2017 17:24:08 GMT):
This one is to add supported ansible version .https://gerrit.hyperledger.org/r/#/c/15435/ this

tongli (Mon, 13 Nov 2017 17:24:33 GMT):
this one is to add a playbook to allow automation to display current fabric network status.

tongli (Mon, 13 Nov 2017 17:24:52 GMT):
this is the second one. https://gerrit.hyperledger.org/r/#/c/15437/

tongli (Mon, 13 Nov 2017 17:25:32 GMT):
I will be adding another patch set to move the docs around to address the jira issue that you opened once these two get merged. Let me know if you have any concerns.

tongli (Mon, 13 Nov 2017 17:25:59 GMT):
@hightall please do review these two patch sets as well. Thanks.

Hi. We are experimenting with Cello for the first time, and wonder about some features: - add more peers to a chain, but on a different physical host - add more organizations to an existing chain. - add a couchdb backend for the peers - deploy chaincodes to peers with Cello Are these on the roadmap? Or, they should be handled by another process? Thanks.

MohammadObaid (Tue, 14 Nov 2017 06:40:26 GMT):
@tongli When ansible create hyperledger network on aws , a chaincode container `dev-peer1st-orga-firstchaincode-1.0` runs on two host `fabric001` and `fabric002` but not on third host `fabric003` ALthough there is no problem in invoking transaction or doing other stuffs but is there any specific reason that chaincode container would only run in two host?

tongli (Tue, 14 Nov 2017 16:41:02 GMT):
@MohammadObaid the example chain ode was installed on all peers and there should be one Chaincode container for every peer of each peer was accessed either by a query or a transaction

tongli (Tue, 14 Nov 2017 16:41:27 GMT):
Of=if

MohammadObaid (Tue, 14 Nov 2017 16:43:54 GMT):
Yeah. I understand but one thing strange for me is that no chaincode container runs on my fabric003 instance but still I was able to invoke transactions and run queries.

tongli (Tue, 14 Nov 2017 18:11:30 GMT):
@MohammadObaid if you should have containers on fabric003 depends on how you layout your fabric network. I can take a look at your configuration file.

MohammadObaid (Tue, 14 Nov 2017 18:14:45 GMT):
@tongli which configuration file ? bc1.yaml file in `ansible/vars` directory or `aws.yml` filr in vars directory?

tongli (Tue, 14 Nov 2017 18:15:14 GMT):
what command did you run to set up your cluster?

tongli (Tue, 14 Nov 2017 18:15:33 GMT):
@MohammadObaid see above question.
