Rails on Docker: Using Docker Compose with Your Ruby on Rails Apps

In the previous tutorial, you learned how to get a simple Ruby on Rails app up and running on Docker containers.As you work on your app, it often becomes difficult (and tiresome) to remember all the different configurations and arguments you need to create and link containers. The complexity increases as your app’s dependencies grow (such as when you need to using Sidekiq and to handle background jobs).Thankfully, Docker comes with a great solution to this problem in the form of Docker Compose.
