Where to include core.yaml in Hyperledger Fabric?

Question

I am working on Hyperledger fabric and trying to retrieve historical transaction records from the network. So, i found core.yaml config to enable ledger historic database. But, i don't find where to include the "core.yaml" in the application source repository.

I found few clues to add the file in docker-compose.yaml as

CORE_VM_ENDPOINT=core.yaml

So, is it the correct way of adding the "core.yaml" in the docker-compose.yaml file.?

docker-compose.yaml

version: '2'

Please suggest me some solution

Answer 1

NO its not.

CORE_VM_ENDPOINT starts chaincode containers on the same bridge network as the peers.

You can mount the path of the folder containing core.yaml file on the peer container

If you are using fabric samples go to bellow path

fabric-samples/firest-network/base/

add the bellow code to the volumes section of peer-base.yaml if you want all peers to have history enabled OR add to the volumes of selective peers in docker-compose-base.yaml file

- "Path/to/the/folder/where/core.yaml/exists":/var/hyperledger/config

If any doubts do revert.
