Introduction

The Docker Engine can be used running native Docker style container workloads on Rocky Linux servers. This is sometimes preferred to running the full Docker Desktop environment.

Add the docker repository

Use the dnf utility to add the docker repository to your Rocky Linux server. Type:

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

Install the needed packages

Install the latest version of Docker Engine, containerd, and Docker Compose, by running:

sudo dnf -y install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Start and enable the systemd docker service (dockerd)

Use the systemctl utility to configure the dockerd daemon to automatically startup with the next system reboot and simultaneously start it for the current session. Type:

sudo systemctl --now enable docker
