Connect to Google Cloud SQL from App Engine instance

I want to run an elixir application in the flexible environment of Google App Engine.

I also have a postgresql server running on Google Cloud SQL.

I am able to deploy the application in a docker container. The problem is that I cannot find how to configure the connection to the postgresql server.

As far as I know, the App Engine instance is running the Cloud SQL Agent but I keep getting the following error in the instance: [Error] Postgrex.Protocol(#PID ) cannot connect: **(DBConnection. ConnectionError )tcp connect(localhost:5432): Connection refused – :econnrefused
