Looking to install Docker on Fedora? Docker simplifies application deployment by using containers. Follow this optimized guide to set up Docker effortlessly on your Fedora system.
What is Docker?
Docker is an open-source platform that allows developers to automate the deployment, scaling, and management of applications using containerization. Containers are lightweight, portable units that package an application along with all its dependencies, libraries, and configuration files, ensuring that the application runs consistently across various environments.
Unlike virtual machines, containers share the host system's operating system, making them faster to start and more resource efficient. Docker simplifies the development workflow, enhances application isolation, and enables seamless deployment across cloud, on-premises, and hybrid infrastructures.
Steps before Installing Docker.
Step 1: Update Your Fedora System
Keeping your system updated ensures compatibility and security. Run the following command in your terminal:
sudo dnf update -y
This updates all installed packages to their latest versions
Step 2: Removing older version (if installed)
If you have an older version of Docker, you may want to remove it to prevent package conflict. This reduces chances of installation errors.
To do this, run the command below.
sudo dnf remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
Install Docker
Step 3: Install dnf-plugins-core
Ensure the dnf-plugins-core package is installed:
sudo dnf -y install dnf-plugins-core
Step 4: Add repository to the local package manager
Docker is not included in Fedora’s default repositories. To access it, enable Docker’s official repository:
sudo dnf-3 config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo
Step 5: Install Docker Engine
sudo dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
Steps to make Docker run rootless
Run all these steps to get Docker running rootless.
sudo modprobe ip_tables
Run this shell script that ships with the Docker installation to make Docker run rootless.
dockerd-rootless-setuptool.sh install
Time to do a test run with Docker
docker run hello-world
If this runs without any error, we got Docker up and running rootlessly.
That's it folks, now go be a pirate and ship containers!
