How To Install Docker on Fedora 35/34/33

Docker is container-based application framework, which wrap of a specific application with all its dependencies in a container. Docker containers can easily ship to a remote location on start there without making the entire application setup.

This tutorial will help you to install Docker on Fedora Linux systems.

Prerequisites

For the standard installation, Docker required a 64-bit operating system having Kernel >= 3.10 version. Older versions of Kernel have some missing requirements to run all features of Docker.

uname -r 

4.16.5-300.fc28.x86_64

Step 1 – Enable DNF Repository

Let’s add the official Docker yum repository to your system. Also, update the package’s metadata cache.

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

Step 2 – Install Docker on Fedora

Now 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 

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

sudo systemctl enable docker.service 
sudo systemctl start docker.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 above images have been downloaded successfully on your system. 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. 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 use 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
