Welcome to our guide on how to install Docker CE on Fedora 36/35/34/33/32/31 Linux distribution. The release of Docker we’ll install is Docker Community Edition (CE). Docker is a leading container runtime engine that allows you to package your applications with all of its dependencies into a standardized unit for software development.
Follow the steps below to install Docker CE on Fedora 36/35/34/33/32/31 Linux system.
Step 1: Update your system
Before we install Docker on Fedora 36/35/34/33/32/31 Linux machine, we’ll start our installations by updating and upgrading OS packages. On Fedora, this can be easily done by running the command:
sudo dnf -y updateIt is recommended to reboot your system after an upgrade
sudo rebootStep 2: Add Docker CE repository on Fedora 36/35/34/33/32
After upgrading system packages and rebooting the server, proceed to add Fedora repository to your system:
sudo dnf -y install dnf-plugins-coreFedora 36:
sudo tee /etc/yum.repos.d/docker-ce.repo<Fedora 35:
sudo tee /etc/yum.repos.d/docker-ce.repo<Fedora 34:
sudo tee /etc/yum.repos.d/docker-ce.repo<Fedora 33:
sudo tee /etc/yum.repos.d/docker-ce.repo<Fedora 32:
sudo tee /etc/yum.repos.d/docker-ce.repo<Fedora 31:
sudo tee /etc/yum.repos.d/docker-ce.repo<Step 3: Install Docker CE on Fedora 36/35/34/33/32/31
Now that you have your repository ready, install the latest stable release of Docker CE on your machine by running:
sudo dnf makecache
sudo dnf install docker-ce docker-ce-cli containerd.ioPress the y key when prompted to start the installation.
