  Documentation for Docker Official Images in docker-library (by docker-library)

  

We've just followed the official documentation to add a PostgreSQL database server. This will act as an application container, as our app will soon be depended on it. And in order to make sure that the database container is always started whenever we start our application container, we've added a new depends_on key to the app service and let it know which other service(s) it, well, depends on. This will make sure that the database server is up and running before the app. You may also have noticed that we've mounted volume to our database server's datapath a bit differently. This is known as "named volume". We'll discuss it a bit more in another part, it's not relevant to what we're learning here.
