dockerized-app

Sample rails app Dockerfile and resources Some elements <####> are missing within the Dockerfile, your task is to understand what should be written instead of these placeholders.

hints:

• Gemfile is a 'plugin' definition for Rails, it should be present within the root folder of the app, Gemfile.lock should also be present
• The command needed to perform an application creation is rails new <path> --database=postgresql, we wont automatize this, you should perform it manually
• The command needed to perform a database creation is rake db:create, we wont automatize this, you should perform it manually
• docker/database.yml is a database configuration file for Rails, it should be used at runtime, explain why
