Welcome to our guide on how to install Docker CE on Fedora 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 32/31/30 Linux system.
Step 1: Update your system
Before we install Docker on Fedora 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 update
It is recommended to reboot your system after an upgrade
sudo reboot
Step 2: Add the Docker CE repository to Fedora 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 32:
sudo tee /etc/yum.repos.d/docker-ce.repo<<EOF
[docker-ce-stable]
name=Docker CE Stable - \$basearch
baseurl=https://download.docker.com/linux/fedora/31/\$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg
EOF
Fedora 31/30/29:
sudo dnf config-manager \
--add-repo \
https://download.docker.com/linux/fedora/docker-ce.repoStep 3: Install Docker CE on Fedora 32/31/30
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.
