How to Install Docker on Fedora 36 / Fedora 35


Docker is an open-source container virtualization technology that has recently gained immense popularity. It offers a more efficient way to develop and deploy an application in a containerized format.

With Docker, the application resides inside the container and runs on top of the host operating system.

Here, we will see how to install Docker on Fedora 36 / Fedora 35.

Install Docker on Fedora 36 / 35

Uninstall old Docker versions

Remove the old Docker package called docker or docker-engine along with its dependencies. If your machine does not have a Docker package, skip the step below.

sudo dnf remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine

Contents such as images, volumes, and networks stored under the /var/lib/docker/ directory are preserved.

Add Docker Repository

The Docker package is now called docker-ce. Let’s add the Docker engine repository to your system.

sudo dnf -y install dnf-plugins-core

sudo dnf config-manager --add-repo

Install Docker Engine

Now, install the latest version of the Docker package using the dnf command.

sudo dnf install -y docker-ce docker-ce-cli docker-compose-plugin
If you want to install a specific Docker version, then you can append the version like docker-ce-<version> in the dnf command Ex: sudo dnf install -y docker-ce-3:20.10.16-3.fc36. To find the available Docker versions, use the dnf list docker-ce --showduplicates | sort -r command.

After installing the Docker engine, start and enable the Docker service.

sudo systemctl enable --now docker

You may also want to verify the Docker version with the below command.

docker -v


Docker version 20.10.17, build 100c701

Verify Docker Installation

To test the Docker installation, we will run the hello-world container.

sudo docker run -it fedora echo Hello-World

When we run a docker run command, Docker starts a container with a Fedora image and echoes the command Hello-World in the console.

By default, Docker checks the container image locally; if it doesn’t find it, it will start downloading the Docker image from the Docker registry or private registry. Once the image has been downloaded, Docker will start the container.

The output may look like the below.

Unable to find image 'fedora:latest' locally
latest: Pulling from library/fedora
e1deda52ffad: Pull complete
Digest: sha256:cbf627299e327f564233aac6b97030f9023ca41d3453c497be2f5e8f7762d185
Status: Downloaded newer image for fedora:latest

Allow Non-root users to run Docker Commands

By default, standard Linux users do not have privileges to run Docker commands because the Docker daemon uses a Unix socket owned by the root.

So, to allow standard Linux users to execute Docker commands, add  the user to the docker group.

sudo usermod -aG docker my_user

Then, log out and log in back and run Docker commands without prefixing sudo in the terminal.

docker run hello-world
