Unable to run dockerized strapi app on ubuntu server with postgres db via Gitlab CI

Questions and Answers Strapi Backend

Have you tried to connect to DB from Ubuntu’s CLI? Have you verified that all docker images are running/ports are exposed and checked their logs?

From postgres image I see that you are not exposing it’s port, which means it is not accessible.

So you should also add:

ports:
      - 5432:5432
