Hyperledger Fabric How to delete installed chaincode

Question

Hi.. I installed and created a chaincode but i need to change it because it had something wrong in it. I can create another chaincode with different names but I dont want to do that. I want to delete this and create chaincode with the same name. How can I do it?

Answer 1

One way to do it, that I usually do when I face such problem is by killing and removing the container. You can try this:

docker stop $(docker ps -aq) && docker rm $(docker ps -aq)

Answer 2

The Blockchain data is stored in the /var/hyperledger/production/db directory. So deleting the files in this directory should delete the chaincode. Use the following commands:

$ cd /var/hyperledger/production/db
$ rm - rf *

Answer 3

The chaincode will be deleted if you remove the container. You can do it like this:

$ docker stop <container id>
$ docker rm <container id>
