How can I install Docker CE on Linux Mint 21?, How can I install Docker Compose on Linux Mint 21?. This guide will answer above questions by showing you a step by step installation of Docker and Docker Compose on Linux Mint.
Docker has been the defacto container engine since its arrival. It enables you to package and run your applications in isolated containers within a single host or cluster of Linux hosts.
Docker Engine is available in Community Edition (CE) and Enterprise Edition (EE). In this guide, we will do the installation of Docker Community Edition on Linux Mint using below steps.
Step 1: Install Dependency packages
Start the installation by ensuring that all the packages used by docker as dependencies are installed.
sudo apt update
sudo apt -y install apt-transport-https ca-certificates curl software-properties-common
sudo apt -y remove docker docker-engine docker.io containerd runcStep 2: Add Docker’s official GPG key
Import Docker GPG key used for signing Docker packages.
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpgStep 3: Add the Docker repository
Add Docker upstream repository to your Linux Mint 21 so you can install the latest stable release of Docker.
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu jammy stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/nullThe command above will add a new line to additional repositories file.
$ cat /etc/apt/sources.list.d/docker.list
deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu jammy stableStep 4: Install Docker Engine and Compose
Update the apt package index.
$ sudo apt update

Then install the latest version of Docker CE and Docker Compose
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-pluginThe docker group is created but no users are added. Add your normal user to the group to run docker commands as non-privileged user.
sudo usermod -aG docker $USER
newgrp dockerCheck the version of docker installed
