Query : How to change 8080 port for datahub-gms for docker based installation?            Tried approaches: 1. Changed port for datahub-gms mentioned in docker-compose.yml file pre-container creation. Container creation successful but below error encountered when trying to access the datahub-gms rest backend. 2. Installed through quickstart.sh after making changes to supposedly required files. Container creation successful but same error again encountered. 3. Tried alternate open ports with same issue being replicated.   ERROR: ConnectionError: HTTPConnectionPool(host='X.Y.Z.A', port=8082): Max retries exceeded with url: /config (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at  0x7f8537d00f50>:   Failed to establish a new connection: [Errno 111] Connection refused'))

Hey. Are you trying to change the port inside the container or ones that are forwarded to localhost?
