I want to run an elixir application in google app engine flexible environment.
I also have a postgresql server running on google cloud SQL.
I am able to deploy the application inside the docker container. The problem is that I can't find how to configure the connection to the postgresql server.
As far as I understand the app engine instances run the cloud SQL proxy but I keep getting the following error inside the instance: [error] Postgrex.Protocol (#PID<0.232.0>) failed to connect: ** (DBConnection.ConnectionError) tcp connect (localhost:5432): connection refused - :econnrefused
