Install Docker

We'll use curl to install Docker:

$ curl -sSL get.docker.com | bash

Once installed, check if it is working properly:

$ sudo docker info

You have to use sudo for all Docker commands. It can become painful very quickly when you have to frequently enter Docker commands. To remedy this, we'll add your current user $(whoami), to docker group:

$ usermod -aG docker $(whoami)

Once this is done, you will need to logout and login again to your computer so that the above change can take affect.

If you have logged in to a machine via SSH, just close the SSH session and login again.

To make sure that the user has been added to docker group, run the following command and expect no errors:

$ docker info

Voila, you just installed Docker! 🎉

Let's spin up a container in the next lesson.
