How to 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 application deployment within the software container. The container allows the developer to package all the project resources such as libraries, dependencies, assets, etc. Docker is written in Go programming language and is developed by Dot cloud. It is basically a container engine that uses Linux kernel features such as namespaces and control groups to create containers on top of an operating system and automates the deployment of the application to the container.

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

previous requirements

curl -fsSL | sudo apt-key add -

Next, add the Docker repository to Linux Mint:

sudo add-apt-repository "deb [arch=amd64] $(. /etc/os-release; echo "$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 that will run docker commands:

sudo usermod -aG docker $USER

After that, verify the Docker installation using the following command:

sudo docker --version

Docker is used with the syntax shown below:
