Welcome to our guide on how to install Docker CE on Fedora 34/33/32/31/30 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 34/33/32/31/30 Linux system.
Step 1: Update your system
Before we install Docker on Fedora 34/33/32/31/30 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 the Docker CE repository to Fedora 34/33/32/31/30
After upgrading system packages and rebooting the server, proceed to add Fedora repository to your system:
sudo dnf -y install dnf-plugins-coreFedora 34:
sudo tee /etc/yum.repos.d/docker-ce.repo<<EOF
