If you type just docker it will tell you docker is not installed but give you a hint as to what to do, but read the rest of the article.

$ docker
The program 'docker' is currently not installed. You can install it by typing:
$ sudo apt install docker.io

You can simply install using this command, but if you want to update more frequently use the step below this command.

$ sudo apt install docker.io

Install the pre-reqs.

$ sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

Add the docker GPG key and verify it.

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
OK
$ sudo apt-key fingerprint 0EBFCD88

Add the ubuntu docker repo for amd64

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Update the packages for the repo you just added.

$ sudo apt-get update

Install the docker community edition.

$ sudo apt-get install docker-ce
