How To Install Docker on Fedora 35

In this tutorial, we will show you how to install Docker on Fedora 35. For those of you who didn’t know, Docker is a container-based application framework, which wraps up a specific application with all its dependencies in a container. Containers are usually isolated from one another and bundled their own software libraries and configuration files, they can communicate with each other through well-defined channels.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Docker Community Edition (CE) on a Fedora 35.

Prerequisites

• A server running one of the following operating systems: Fedora 35.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Docker on Fedora 35

Step 1. Before proceeding, update your Fedora operating system to make sure all existing packages are up to date. Use this command to update the server packages:

sudo dnf upgrade
sudo dnf update
sudo dnf install dnf-plugins-core

Step 2. Installing Docker on Fedora 35.

By default, Docker is available on Fedora 35 base repository. Now we run the following command below to add Docker repository to your Fedora system:

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/35/\$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://download.docker.com/linux/fedora/gpg
EOF

Next, update packages and install the latest stable release of Docker CE using the following command:

sudo dnf makecache
sudo dnf install docker-ce docker-ce-cli containerd.io

Once installation is complete we need to start the Docker server to start operating. We do that with the following command below:

sudo systemctl start docker
sudo systemctl enable docker

Let’s check the version of the installed Docker:

docker version

Output:

Client: Docker Engine - Community
Version:           20.10.14
API version:       1.41
Go version:        go1.16.9
Git commit:        dea9396
Built:             Thu Dec 09 17:08:10 2021
OS/Arch:           linux/amd64
Context:           default
Experimental:      true

Step 3. Use Docker Images.

Now we search Docker container images from the Docker hub. For example, the below command will search all images with Ubuntu and list them as output:

sudo docker search ubuntu

Next, we can pull the Docker image with the following command. As an example let me pull the Ubuntu image from the Docker hub:

sudo docker pull fedora

Finally, launch a Docker container using the above-downloaded image on your system use the following command:

sudo docker run -i -t -d ubuntu /bin/bash

Congratulations! You have successfully installed Docker. Thanks for using this tutorial for installing the Docker container on your Fedora 35 system. For additional help or useful information, we recommend you check the official Docker website.
