How to Remove Older Versions Chaincode Containers after the chaincode instance is upgraded?
✍: FYIcenter.com
After a chaincode instance is upgraded, chaincode containers of
the old version are still running on the Docker Engine.
You can follow this tutorial to remove them.
1. List all chaincode containers:
$ docker ps --all | grep chaincode dev-peer0.org2.example.com-mycc-2.0-03c5... dev-peer0.org2.example.com-mycc-2.0 dev-peer0.org1.example.com-mycc-2.0-04da... dev-peer0.org1.example.com-mycc-2.0 dev-peer0.org1.example.com-mycc-1.0-7782... dev-peer0.org1.example.com-mycc-1.0 dev-peer0.org2.example.com-mycc-1.0-6109... dev-peer0.org2.example.com-mycc-1.0
2. Stop version 1.0 chaincode containers:
$ docker stop dev-peer0.org1.example.com-mycc-1.0 $ docker stop dev-peer0.org2.example.com-mycc-1.0
3. Remove version 1.0 chaincode container images:
$ docker rm dev-peer0.org1.example.com-mycc-1.0 $ docker rm dev-peer0.org2.example.com-mycc-1.0
4. List all chaincode containers again:
$ docker ps -all | grep chaincode dev-peer0.org2.example.com-mycc-2.0-03c5... dev-peer0.org2.example.com-mycc-2.0 dev-peer0.org1.example.com-mycc-2.0-04da... dev-peer0.org1.example.com-mycc-2.0
5. Verify the chaincode instance:
$ docker exec -it cli bash bash-4.4# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}' 80
Now only 2 containers are running for the version 2.0 of the chaincode instance. One for each participating peer.
