How to remove old chaincode containers and chaincode images in Azure Hyperledger Fabric?

Question

Hi,
I am using Azure Hyperledger Fabric. I have 3 peer organizations in my blockchain network. I upgrade the chaincode multiple times. Also I install new chaincode on certain occasions. Hence, I want to remove/delete the old chaincode containers as I no longer need them.

How can this be done?

Thanks.

To remove a chaincode on a peer you need to:

• Kill the container that corresponds to the chaincode shim since a chaincode runs inside a docker container.
• Delete the chaincode from the file system of the peer under /var/hyperledger/production/chaincodes

You can also delete docker image of the chain code created using the below command.

Note: You need to SSH into the AKS nodes to run the commands. For instructions, please check SSH to Azure Kubernetes Service (AKS) cluster nodes

docker images  
docker rmi $(docker images chaincode_name -q)
