This guide will take you through how to install Docker Engine on Linux systems i.e. Debian / Ubuntu / CentOS / Rocky / Arch Linux / Open SUSE. Docker is a popular open-source platform used for creating, deploying, and managing applications in containers. Containers are lightweight, portable, and self-contained environments that can run software applications and their dependencies in a standardized way, regardless of the underlying infrastructure.
Docker enables developers to package their applications into a container image that includes all the necessary libraries, dependencies, and configuration files. These container images can then be easily distributed and deployed on any platform that supports Docker, such as a local machine, cloud provider, or on-premises server.
Docker provides a range of tools and services for managing containers, including Docker Engine, Docker Compose, and Docker Swarm. Docker Engine is the core component that runs and manages containers, while Docker Compose allows users to define and run multi-container applications. Docker Swarm is a container orchestration platform that enables users to manage and scale container clusters.
Benefits of using Docker include improved application portability, easier deployment and scaling, reduced infrastructure costs, and greater efficiency and flexibility in managing and updating applications. Docker has become an essential tool for modern application development and deployment and is widely used by developers and organizations of all sizes.
In this guide, we will learn how to Install Docker Engine on Debian / Ubuntu / CentOS / Rocky / Arch Linux / Open SUSE.
Install Docker Engine on Linux Systems
Install Docker Engine on Linux Systems as shown below;
1. Install Docker Engine on Debian 12/ Debian 11 / Debian 10
Begin by updating the package repositories:
sudo apt updateInstall the required packages:
sudo apt install lsb-release gnupg2 apt-transport-https ca-certificates curl software-properties-common -yImport the GPG key for Docker:
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/debian.gpgNow add the stable Docker repository:
sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/debian $(lsb_release -cs) stable"Update the APT package index and install all the docker packages:
sudo apt update && sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin -yOnce installed, add your system user to the docker group:
sudo usermod -aG docker $USER
newgrp docker2. Install Docker Engine On Ubuntu 18.04|20.04|22.04
To install the Docker engine on Ubuntu 18.04|20.04|22.04, follow the below steps.
First, update the APT package index:
sudo apt updateRemove any previous Docker packages:
sudo apt remove docker docker-engine docker.io 2>/dev/nullInstall the required packages:
sudo apt -y install lsb-release gnupg apt-transport-https ca-certificates curl software-properties-commonAdd the official Docker repository keys:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker.gpgAdd the Docker repo on Ubuntu:
sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"Update your system and install Docker CE using the command:
sudo apt update && sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-pluginOnce the installation is complete, add your system user to the Docker group:
sudo usermod -aG docker $USER
newgrp dockerVerify the installation:

GitCommit: de40ad03. Install Docker Engine on Rocky Linux|Alma Linux|CentOS
Begin by uninstalling old Docker packages:
sudo yum remove docker docker-common docker-selinux docker-engineInstall the required packages:
sudo yum -y install yum-utils device-mapper-persistent-data lvm2Then add the stable repository:
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repoNow install Docker CE on Rocky Linux|Alma Linux|CentOS
sudo yum -y install docker-ce docker-ce-cli containerd.io docker-compose-pluginIf the installation fails, use the –allowerasing flag as shown:
sudo dnf install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin --allowerasingStart and enable the Docker service:
sudo systemctl start docker && sudo systemctl enable dockerAdd your system user to the Docker group:
sudo usermod -aG docker $USER
newgrp docker4. Install Docker Engine on Fedora 38/37/36/35/34/33
Docker Engine can also be installed on Fedora Linux. To achieve this, follow the below steps:
First, remove any previous installations:
sudo dnf remove docker docker-common docker-selinux docker-engine-selinux docker-engine 2>/dev/nullThen add the Docker repo to your system:
sudo dnf -y install dnf-plugins-core && sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repoInstall Docker CE on Fedora:
sudo dnf install docker-ce docker-ce-cli containerd.io docker-compose-pluginStart and enable the Docker service:
sudo systemctl start docker && sudo systemctl enable dockerFinally, add your system user to the Docker Group:
sudo usermod -aG docker $USER
newgrp docker5. Install Docker Engine On RedHat Linux
To install Docker CE on Rhel, first, add the repository with the command:
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/rhel/docker-ce.repoInstall Docker CE on RHEL with the command:
sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-pluginStart and enable the Docker service on the system:
sudo systemctl start docker
sudo systemctl enable dockerAdd your system user to the Docker group:
sudo usermod -aG docker $USER
newgrp docker6. Install Docker Engine on SLES|OpenSUSE
It is also possible to install Docker on SUSE systems. This requires you to follow the below steps:
Enable the OpenSUSE SELinux repo on your system:
sles_version="$(. /etc/os-release && echo "${VERSION_ID##*.}")"
opensuse_repo="https://download.opensuse.org/repositories/security:SELinux/SLE_15_SP$sles_version/security:SELinux.repo"
sudo zypper addrepo $opensuse_repo Now add the stable Docker repo:
sudo zypper addrepo https://download.docker.com/linux/sles/docker-ce.repo
sudo zypper install docker-ce docker-ce-cli containerd.io docker-compose-pluginNow start and enable the service:
sudo systemctl start docker
sudo systemctl enable dockerAdd your system user to the Docker Group:
sudo usermod -aG docker $USER
newgrp docker7. Install Docker Engine on Arch Linux|Manjaro|EndeavourOS
Here, you need to have yay installed on your system. To install yay, use the commands:
sudo pacman -S --needed git base-devel
git clone https://aur.archlinux.org/yay-bin.git
cd yay-bin
makepkg -siOnce installed, use it to install Docker as shown:
yay -S --noconfirm --needed dockerFinally, add your system user to the Docker group:
sudo usermod -aG docker $USER
newgrp dockerClosing Thoughts
