How to install Docker on Rocky Linux 8

Jul 05, 2021 · 2 mins read · Post a comment

In the early December last year, Red Hat took us all by surprise with the CentOS 8 End Of Life (EOL) announcement, that was scheduled for the end of 2021. In response to this, the original CentOS founder has created a fresh project which is called Rocky Linux. The project quickly gained its popularity among many clients of the cloud computing giants AWS, Azure and Google Cloud. This is a great opportunity for the distro to proof Docker capabilities.

In the following steps, we will see how we can quickly install and setup Docker CE.


  • Rocky Linux 8
  • sudo privileges

Add Docker repository

Step 1. Update system OS packages.

sudo dnf update -y

Step 2. Add Docker repository.

sudo dnf config-manager --add-repo=


Adding repo from:

Step 3. We can confirm it by listing current enabled repositories.

dnf repolist


repo id                 repo name
appstream               Rocky Linux 8 - AppStream
baseos                  Rocky Linux 8 - BaseOS
docker-ce-stable        Docker CE Stable - x86_64
extras                  Rocky Linux 8 - Extras

Install Docker

Step 4. Install Docker.

sudo dnf install -y docker-ce docker-ce-cli

Step 5. Enable Docker to start on boot.

sudo systemctl enable --now docker


Created symlink /etc/systemd/system/ → /usr/lib/systemd/system/docker.service.

Step 6. Start Docker service.

sudo systemctl start docker

Verify and test Docker installation

Step 7. To verify Docker service running, run the following command:

sudo systemctl status docker

Step 8. As a best practice, we should always run Docker as a non-root user (user without sudo privileges).

sudo usermod -aG docker $USER

Step 9. Confirm that you are part of the docker group.

Step 10. Make sure you can run Docker commands.

sudo docker --version


Docker version 20.10.7, build f0df350

Step 11. Let’s test things out by spinning up a hello-world container.

sudo docker run --rm --name test-me hello-world


Installing Docker on Rocky Linux 8 should be an easy procedure, and it’s kinda the same as installing on any other Linux distribution. In some of the future posts, we will cover on how you can install Docker Compose as well.
