How To Install Docker on Linux Mint 20

Install Docker on Linux Mint 20

In this tutorial, we will show you how to install Docker on Linux Mint 20. For those of you who didn’t know, Docker is an open-source project that automates the deployment of the application inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets, etc. Docker is written in a Go Programming language and is developed by Dot cloud. It is basically a container engine that uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Docker on a Linux Mint 20 (Ulyana).

sudo snap install docker
  • Install Docker from the official source:

Now we add Docker official key to your Linux Mint system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Next, add Docker repository to Linux Mint:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(. /etc/os-release; echo "$UBUNTU_CODENAME") stable"

Then, install Docker CE using the following command:

sudo apt update
sudo apt install docker-ce

Once installed a docker group will be created. Add your user to the group who will be running docker commands:

sudo usermod -aG docker $USER

sudo docker --version

$ docker help
