Let's ensure that our Docker setup works perfectly. For our purpose, Docker Community Edition should suffice (https://www.docker.com/community-edition). Once we have it installed, we will check if it works by running a few basic commands.
Let's start by checking what version we have installed:
$ docker --version Docker version 17.12.0-ce, build c97c6d6
Let's try to dig deeper into details about our Docker installation:
$ docker infoContainers: 38 Running: 0 Paused: 0 Stopped: 38Images: 24Server Version: 17.12.0-ce
