How To Install and Use Docker on Fedora 37/36/35

Docker is a container-based virtualization platform that has revolutionized the way developers build, deploy, and manage applications. It simplifies the process of creating, deploying, and managing containers on multiple operating systems. In this article, we will discuss how to install and use Docker on Fedora, one of the most popular Linux desktop distributions.

Installing Docker on Fedora

The Docker team provides an official repository containing the Docker engine RPM packages. You just need to configure the RPM repository on your system to install the Docker engine.

1. Remove all the existing installed Docker packages from your system. The following command will help you to remove older Docker packages from your system:

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

2. Next, install the dnf-utils package that provides dnf-config-manager command line utility:

   sudo dnf install dnf-utils 
   

3. Add the official Docker rpm repository with the following command:

   sudo dnf-config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo 
   

4. Finally, install the docker community edition package to install docker on your system. This is installed in many of the required decencies on your system.

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

5. After the successful installation of the Docker engine, Let’s enable and start the docker service. Also, enable the containerd service.

   sudo systemctl enable docker.service 
   sudo systemctl start docker.service 
   sudo systemctl enable containerd.service 
   

   Then check the status of the Docker service.

   

Docker has been installed and running on your system. You can visit our Docker tutorial section to work with Docker containers.

How to Use Docker?

Search Docker Images

First of all search Docker container images from the Docker hub. For example, the below command will search all images with Fedora and list them as output

sudo docker search fedora 

Download Docker Images

Now download the Docker container with the name Ubuntu on your local system using the following commands.

sudo docker pull fedora 

Output:
Using default tag: latest
latest: Pulling from library/fedora
0be2a68855d7: Extracting [==============================>     ]  69.63MB/89.87MB

Now make sure that the above images have been downloaded successfully on your system. The below command list all images.

sudo docker images

Output:
REPOSITORY  TAG            IMAGE ID            CREATED             VIRTUAL SIZE
ubuntu      latest         36248ae4a9ac        2 days ago          188 MB
fedora      latest         26ffec5b4a8a        2 weeks ago         275MB

Launch New Container with Image

Finally, launch a Docker container using the above-downloaded image on your system. The below command will start a new container.

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

To view all running containers type

sudo docker ps 

Output:
CONTAINER ID     IMAGE     COMMAND        CREATED          STATUS         PORTS    NAMES
695efa2ace69     fedora    "/bin/bash"    58 seconds ago   Up 56 seconds           first_fedora

By default Above command will list only running containers. To list all containers (including stopped containers) use the following command.

docker ps -a 

Start/Stop/Attach Container

You can start, stop or attach to any containers with the following commands. To start the container using the following command.

docker start container_id 

To stop a container, type:

sudo docker stop container_id 

To attach to the currently running container use the following command.

sudo docker attach container_id
