How to uninstall chaincodes on BYFN Peers?

✍: FYIcenter.com

A

Unfortunately, the BYFN CLI "peer chaincode" command does offer any option to uninstall chaincodes from a given peer.

You have two options when your chaincodes from different peers are out of sync or incompatible:

1. Destroy chaincode instance and re-install chaincode on all peers.

Stop the chaincode container running on the Docker engine.
Remove the chaincode container image from the Docker engine. The chaincode instance data will be gone.
Re-install the chaincode on all peers.
Instantiate the chaincode from one peer.

2. Upgrade chaincode instance to the next version to fix the issue.

Install the chaincode as a new version on all peers with the same chaincode source code.
Upgrade the chaincode instance to the new version from one peer.
