Docker

Digital Ocean (DO) is a great source for tutorials about using and managing Docker on Ubuntu.

There is surely also the Docker Blog (DB) for tutorials and news about Docker.

Here are the main themes you should be familiar with to get docker running on Ubuntu. You should at least read an test around the articles in the general section until you will be able to be productive - believe me or not, you'll see!

The following gives you a base idea but without Docker Composer (next section) you'll miss the real fun. It only shows you how to save the state of a container as a new Docker image.

• General installation and usage on 16.04 (DO)

Docker Compose (I consider this the most interesting article):

• DO - Docker-Compose AKA Fig (DO)
• Docker Compose File (YML) Reference (docker.com)
