Hyperledger Fabric altering fabcar example

Question

I\'ve been working through the fabcar example and have it running it perfectly when no alterations have happened. What I\'m trying to do is update the fabcar.go code to add

Answer 1

I would suggest two possible approaches:

1. Install chaincode with new name or incremented version

Same name, but updated version:

peer chaincode install -n fabcar -v 2.0 -p github.com/fabcar

or same version, but new name:

peer chaincode install -n tickets -v 1.0 -p github.com/fabcar

2. Cleanup old chaincode container and install updated version of alternated chaincode over again.

You can use following command to remove old chaincode container image:

docker images | grep fabcar | awk '{print $2}' | docker rmi
