Answer 1

when developing chaincode on hyperledger fabric.

1: we have to remove chaincode docker image for testing each change. For Example: name of install chaincode is mycc

#remove container
docker rm -f $(docker ps -aq)
#remove images
docker rmi mycc-0-container id or name

2: you can install chaincode just by changing its name like mycc is currently running then you have to change mycc1 and now you need to use mycc1 and perform your transactions. For Example:

#Already install chaincode has named mycc
#following command will install same chaincode(updated) with chaincodeName
#mycc1
docker exec cli peer chaincode install -n mycc1 -v 0 -p github.com/sacc

Note: now you need to instantiate , invoke and query chaincode with name mycc1.
