docker hyperledger-fabric hyperledger blockchain chaincode

failed to get chaincode container info for mycc:1.0 while executing peer chaincode query for multi machine

I am trying to setup a hyperledger network with 2 orgs running on 2 different physical machine. So machine 1 has orderer, peer0.org1, peer1.org1, ca-org1, couchdb1, couchdb2 and cli containers. Machine 2 has peer0.org2, peer1.org2, ca-org2, couchdb3, couchdb4 and cli container.

Below is the docker-compose-org1.yaml file -

As you can see I am using "extra_hosts" to connect to the docker container in other machine. This way I am able to create channel from one machine and join the channel for both peers from that machine. In the other machine I fetched the same channel config and join the same channel for both peers. I checked that all 4 peers in both machines have joined the same channel by below command -

peer channel list
peer channel getinfo -c mychannel

Now from machine 1 I have installed and instantiated chaincode. This is working fine. Used below commands to install and instantiate -

peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/

peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -l golang -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"

If I query the chaincode from the same machine it is working fine and I am getting proper result.

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

But when I am executing the same chaincode query command from different machine it is giving below error -

Error: endorsement failure during query. response: status:500 message:"failed to execute transaction 2444b829db1485ad097b2e11442d65cb36f02de1c6a3f3372ad53594af4d1a4d: [channel mychannel] failed to get chaincode container info for mycc:1.0: could not get chaincode code: chaincode fingerprint mismatch: data mismatch"

I can see the hyperledger fabric is syncing all peers properly in both machines. Because when I run peer channel getinfo -c mychannel I can match the currentBlockHash, previousBlockHash and height value for all 4 peers. I am just not able to execute the peer chaincode query command from the other machine.

When I run peer chaincode instantiate command I can see a new docker container is created in machine 1 which is for running chaincode. But there is no such container in machine 2. Am I missing any configuration here so that the chaincode container created on machine 1 can be accessed from machine 2?

New findings: I have installed chaincode on all 4 peers in both machines by running peer chaincode install command from the CLI container. I have two CLI container running in two machines.

When I run the command peer chaincode list --installed. In machine 1 I get result like below

Name: mycc, Version: 1.0, Path: github.com/chaincode/chaincode_example02/go/, Id: 333a19b11063d0ade7be691f9f22c04ad369baba15660f7ae9511fd1a6488209

When I run the same command in machine 2. The result is same except the Id value is different. But I also found that the Id value is same for both peers on same machine. Probably that's why I am able to execute the chaincode query from both peers on same machine. But not able to run it from other machine. Looks like that's the root cause of this problem.

Solution

I was able to figure out the problem ultimately so posting an answer here. The problem was that when I was installed the chaincode from two different machine the chaincode Id was different. Previously I was using the command peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/ to install the chaincode seperately on two machines. So when I do peer chaincode list --installed it was showing the Id value as different.

I was able to solve it using slightly a different approach. First created chaincode package using the command peer chaincode package ccpack.out -n mycc -l golang -p github.com/chaincode/chaincode_example02/go/ -v 1.0. It will generate a file ccpack.out. Moved this file physically from one machine to another. Then installed the same package file in both machines using the command peer chaincode install ccpack.out. In that way the chaincode Id remains same and it works perfectly.
