Installing Docker on an Ubuntu workstation

As we did on the CentOS workstation, we are going to install Docker CE on our Ubuntu workstation. The requirement for installing Docker CE on Ubuntu is that you have to be running a 64-bit recent LTS release, such as Bionic, Xenial, or Trusty. You can install an edge version of Docker CE onto the Artful version of Ubuntu.

There are three methods to install Docker CE on Ubuntu:

• Via Docker repositories
• Downloading and manually installing the DEB packages
• Running convenience scripts

The most common method used is via Docker repositories, so let's begin there.
