问题
I am running Hyperledger Fabric 1.4.0
I have 1 org (Org1), 2 peers (peer0, peer1) and two orderers (ord0, ord1). The peers use couchdb as a storage backend.
I am able to successfully install my chaincode, then instantiate it.
Looking at peer0 logs, the docker image is built and the container started. peer0 also receives and acknowledges the REGISTER request sent by the chaincode binary within the container:
2019-06-24 10:15:57.003 UTC [dockercontroller] createContainer -> DEBU b563 created container {"imageID": "nid1-peer0-mynet-mychain-v1-613158e6e99c2c9e7d567e8b57fe2dfb56444f7fdcbc263dd1f61626a374843d", "containerID": "nid1-peer0-mynet-mychain-v1"}

2019-06-24 10:15:57.182 UTC [chaincode] handleMessage -> DEBU b56f [1a98f442] Fabric side handling ChaincodeMessage of type: COMPLETED in state ready
Despite this, the chaincode is not registered in couchdb:
$ peer chaincode list --instantiated -C mychannel
2019-06-24 11:26:29.317 BST [main] InitCmd -> WARN 001 CORE_LOGGING_LEVEL is no longer supported, please use the FABRIC_LOGGING_SPEC environment variable
2019-06-24 11:26:29.332 BST [main] SetOrdererEnv -> WARN 002 CORE_LOGGING_LEVEL is no longer supported, please use the FABRIC_LOGGING_SPEC environment variable
Get instantiated chaincodes on channel mychannel:
peer0 logs immediately after submitting the list command:

If I try to invoke a method on the chaincode, I get this error:
Error: endorsement failure during invoke. response: status:500 message:"make sure the chaincode mychain has been successfully instantiated and try again: chaincode mychain not found"
which just confirms that the chaincode has not been registered within the network.
Update
I realised I had missed an important detail: the peer logs repeatedly report errors connecting to the orderer, e.g.:
2019-06-24 11:30:35.931 UTC [ConnProducer] NewConnection -> ERRO 100e6 Failed connecting to ord0.mynet.example.com , error: context deadline exceeded
which might be the reason why the "chaincode instantiated" message doesn't get propagated...
回答1:
After much debugging, it turned out the issue was pretty simple: the peers could not communicate with the orderers.
In my particular case the addresses of the orderers were wrong in configtx.yaml. Fixing them resulted in the chaincode instantiation process tu fully succeed.
