Install Docker in Linux Mint 19.1

Docker Containerisation

One of the first things I wanted to try on my fresh Linux Mint 19.1 install was Docker. This post captures the steps I’ve taken to get Docker CE (community edition) version installed on my Linux-based Dell XPS laptop.

Docker in Linux Mint

Since Linux Mint is based on Ubuntu, you shouldn’t have any issues getting Docker installed from the official repository of Docker.io. I have followed instructions from here: Docker Docs – Install Docker CE in Ubuntu.

I followed instruction pretty much word for word, except the part where you’re adding a new apt repository to your Linux Mint.

In the procedure fully documented below, I have changed this command:

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

to this:

greys@xps:/$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"

This is because Linux Mint has its own version names and they don’t match Ubuntu ones. But because I know that Linux Mint 19.1 is based on Ubuntu Bionic, I just made the replacement as shown above.

Here are the full steps for the installation.

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something more ambitious, you can run an Ubuntu container with:

$ docker run -it ubuntu bash

That’s it!
