Getting error while run the hyperledger using docker-composer - docker-compose

Question

actually I am want to step up hyperledger network using fabric CA, however my CA docker get Exited whenever I up the docker-composer.
I found root cause as it happens because "FABRIC_CA_SERVER_CA_KEYFILE" changing every time however I put it manually.
" - FABRIC_CA_SERVER_CA_KEYFILE=/var/hyperledger/fabric-ca-server-
config/bac7a78da8de5b5071c62cefa3ada1c978dadcce333cb92b5ea9e7c3462ca477_sk". In that variable fact is
"bac7a78da8de5b5071c62cefa3ada1c978dadcce333cb92b5ea9e7c3462ca477_sk"
How can I make it fixed with some variable ID in docker-composer file
My docker-composer-file

there is a file called docker-template.yaml file in fabric samples/firstnetwork/ . Check it. So one template file acts a backup and one docker-composer.yaml file gets updated with new certificates.If you still face error, let me know I can help you from this 😊
