Install Docker

Install Docker Engine on Fedora

To get started with Docker Engine on Fedora, make sure you meet the prerequisites, then install Docker.

Prerequisites -

OS requirements

To install Docker Engine, you need the 64-bit version of one of these Fedora versions:

Fedora 32
Fedora 33
Fedora 34

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

Set up the repository: Install the dnf-plugins-core package (which provides the commands to manage your DNF repositories) and set up the stable repository.

$ sudo dnf -y install dnf-plugins-core

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

If prompted to accept the GPG key, verify that the fingerprint matches 060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35, and if so, accept it.

Install Docker Engine

Install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

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

Start Docker

sudo systemctl start docker

Verify that Docker Engine is installed correctly by running the hello-world image.

sudo docker run hello-world

This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.
