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 has revolutionized the way developers package, deploy, and run applications. By leveraging containerization technology, Docker enables developers to create isolated environments for their applications, ensuring consistency across different systems

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 the step-by-step installation of Docker on a Linux Mint 20 (Ulyana).

Prerequisites

• A server running one of the following operating systems: Linux Mint 20.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Docker on Linux Mint 20 Ulyana

Step 1. To begin, it’s crucial to update your system’s APT (Advanced Package Tool) packages to ensure you have the latest versions available. APT is the package manager used by Linux Mint and other Debian-based distributions. Open a terminal and run the following commands:

sudo apt update

Step 2. Installing Dependencies.

Docker requires certain dependencies to function properly on Linux Mint 20. To install these dependencies, run the following command in your terminal:

sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

Step 3. Installing Docker on Linux Mint 20.

• Install Docker using Snap:

Run the following command to install Snap packages and Docker:

sudo rm /etc/apt/preferences.d/nosnap.pref
sudo apt update
sudo apt install snapd

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 the 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

 To verify that Docker has been installed correctly, you can check the version and run a simple “Hello, World” container. Run the following command to check the Docker version:

sudo docker --version

You should see output similar to:

Docker version 20.10.17, build 100c701

Next, run the “Hello, World” container to ensure Docker is functioning properly:

sudo docker run hello-world

Docker is used with syntax as shown below:

$ docker help

Congratulations! You have successfully installed Docker Thanks for using this tutorial for installing the latest version of Docker on the Linux Mint system. For additional help or useful information, we recommend you check the official Docker website.
