First, install the required package to manage repositories:
sudo dnf install -y dnf-utils
Next, add the official Docker repository:
sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
This repository ensures you receive the latest stable Docker Engine rather than older distribution packaged versions.
Install Docker Engine
Now install Docker and its core components:
sudo dnf install -y docker-ce docker-ce-cli containerd.io

This command installs:
- Docker Engine
- Docker CLI
- Containerd runtime
This is the recommended method for docker installation in linux step by step on RHEL based systems.
Start and Enable Docker Service
After installation, start Docker and configure it to launch automatically on boot:
sudo systemctl start docker
sudo systemctl enable docker
Check the service status:
systemctl status docker
If the service is active, Docker Rocky Linux is running successfully. For a broader Linux perspective, you can also refer to Install Docker on Linux for cross distribution guidance.
How to Install Docker on Rocky Linux 8
The process to Install Docker on Rocky Linux 8 is very similar, but there are a few version specific considerations related to older kernel modules and SELinux policies.
Add Docker Repository on Rocky Linux 8
sudo dnf install -y dnf-utils
sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Install Docker Packages
sudo dnf install -y docker-ce docker-ce-cli containerd.io
Start Docker Service
sudo systemctl start docker
sudo systemctl enable docker
Rocky Linux 8 supports Docker CE fully and remains widely used for long term server deployments. This makes how to install docker on rocky 8 a common requirement for legacy environments.
