Can datahub-gms port be changed via env vars? It doesn't seem that way since the docker image has 8080 hard coded in the dockerfile 🥴

That is internal port. You can port-map for the outside world like this https://github.com/datahub-project/datahub/blob/master/docker/quickstart/docker-compose.quickstart.yml#L94

I managed to solve my problem changing the port of my other service but thanks

BTW the deploy related questions might be better suited for #all-things-deployment instead of #chatter
