Docker<\/a> is a popular containerization platform that allows developers to create, deploy, and run applications in a portable and efficient manner. It simplifies the process of packaging applications and their dependencies into self-contained units called containers, which can run on any Linux-based operating system.<\/p>\n\n\n\n

In this article, we will explore how to install Docker on Linux Mint 21<\/a>, step-by-step. Whether you are a developer, sysadmin, or just getting started with Docker, this guide will help you get up and running with Docker on your Linux Mint 21 system in no time.<\/p>\n\n\n\n

However, if you came across this guide looking for one for Linux Mint 22<\/strong>, you can find it here<\/strong><\/a>.<\/p>\n\n\n\n

Installing Docker on Linux Mint 21<\/h2>\n\n\n\n

You can install Docker on your Linux Mint 21 system in several ways. For example, it is available in the official Mint repositories, where users can easily install it with a single APT command<\/a>. However, one disadvantage to this approach is that the version available is not always the most recent.<\/p>\n\n\n\n

For this reason, this guide will show you how to install Docker on Linux Mint 21 from the official Docker repository so you always get the latest version, and it will automatically receive all future software updates as they become available. So, let’s get started.<\/p>\n\n\n\n

Step 1: Install Prerequisites<\/h3>\n\n\n\n

First, run the two commands below to update the package index and install the prerequisite necessary to add and use a new HTTPS repository.<\/p>\n\n\n

sudo apt update\nsudo apt install apt-transport-https ca-certificates curl gnupg<\/code><\/span>Code language:<\/span> Bash<\/span> (<\/span>bash<\/span>)<\/span><\/small><\/pre>\n\n\n
Once operations are completed, you can move to the next section, where we’ll add the Docker’s repo GPG key and repo itself to our Linux Mint 21 system.<\/p>\n\n\n\n
Step 2: Add Docker\u2019s Official GPG Key<\/h3>\n\n\n\n
Next, import the Docker GPG repository key to your Mint system. This security feature ensures that the software you\u2019re installing is authentic.<\/p>\n\n\n
curl -fsSL https:\/\/download.docker.com\/linux\/ubuntu\/gpg | sudo gpg --dearmor -o \/usr\/share\/keyrings\/docker.gpg<\/code><\/span>Code language:<\/span> Bash<\/span> (<\/span>bash<\/span>)<\/span><\/small><\/pre>\n\n\n
\"Add<\/a>
Add Docker\u2019s repo GPG key.<\/figcaption><\/figure>\n\n\n\n
Notice that the command produces no output.<\/p>\n\n\n\n
Step 3: Add Docker Repo to Linux Mint 21<\/h3>\n\n\n\n
After importing the GPG keys, we\u2019ll add the official Docker repository to our Linux Mint 21 system. This implies that the update package will be made available with the rest of your system\u2019s regular updates if a new version is released.<\/p>\n\n\n
echo<\/span> \"deb [arch=$(dpkg --print-architecture)<\/span> signed-by=\/usr\/share\/keyrings\/docker.gpg] https:\/\/download.docker.com\/linux\/ubuntu jammy stable\"<\/span> | sudo tee \/etc\/apt\/sources.list.d\/docker.list > \/dev\/null<\/code><\/span>Code language:<\/span> Bash<\/span> (<\/span>bash<\/span>)<\/span><\/small><\/pre>\n\n\n
\"Add<\/a>
Add the official Docker repository to Linux Mint 21.<\/figcaption><\/figure>\n\n\n\n
As with the previous command, its execution produces no output.<\/p>\n\n\n\n
Next, refresh the package list.<\/p>\n\n\n
sudo apt update<\/code><\/span>Code language:<\/span> Bash<\/span> (<\/span>bash<\/span>)<\/span><\/small><\/pre>\n\n\n
\"Update<\/a>
Update the package base.<\/figcaption><\/figure>\n\n\n\n
This command updates the package index on our system. As you can see, the newly added Docker repository is now available and ready to be used.<\/p>\n\n\n\n
Step 4: Install Docker on Linux Mint 21<\/h3>\n\n\n\n
Finally, run the below command to install the latest up-to-date Docker release on Linux Mint.<\/p>\n\n\n
sudo<\/span> apt<\/span> install<\/span> docker-ce<\/span> docker-ce-cli<\/span> containerd<\/span>.io<\/span> docker-buildx-plugin<\/span> docker-compose-plugin<\/span><\/code><\/span>Code language:<\/span> CSS<\/span> (<\/span>css<\/span>)<\/span><\/small><\/pre>\n\n\n
\"Install<\/a>
