Description
I'm running into an issue with the following passenger-docker setup (see below), the rails config/application.rb file does pick up the right env vars passed to the docker run command. However, in the stack trace, mysql2 still tries to connect using root and local socket, ignoring the host, username and password env vars that are passed in
Dockerfile

The docker command is docker run -d -e PASSENGER_APP_ENV=development -e DB=appname_development -e DB_USER=user -e DB_PASS=pass -e DB_HOST=10.0.2.2 -p 80:80
