How to Install Docker CE on Ubuntu / Debian / Fedora / Arch Linux and CentOS Linux systems ?. As of this article writing there are two main editions of Docker – Docker CE ( Community Edition) and Docker EE ( Enterprise edition). This article will be focused in the installation of Docker CE on various distributions of Linux operating system.
Docker is a container runtime engine which allows you to package an application with all of its dependencies into a standardized unit for software development.
Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.
Here we’ll cover installation of Docker CE on Ubuntu, Debian, Fedora, and CentOS and Arch Linux distributions.
1) Install Docker CE on Ubuntu Linux
Uninstall Old version of Docker. Old versions of docker had the name docker or docker-engine. If you have it installed, first uninstall it.
sudo apt update
sudo apt remove docker docker-engine docker.io 2>/dev/nullThe Docker CE package is now called docker-ce. Update the apt package index:
sudo apt update
Install packages to allow apt to use a repository over HTTPS:
sudo apt -y install lsb-release gnupg apt-transport-https ca-certificates curl software-properties-commonAdd Docker’s official GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker.gpgAdd stable repository:
sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"Install docker ce:
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-pluginIf you would like to use Docker as a non-root user, you should now consider adding your user to the “docker” group with something like:
sudo usermod -aG docker $USER
newgrp dockerRun the command below to see a version of docker installed.
