Podman is a container management tool that allows you to run containers without requiring a daemon. It’s compatible with Docker and provides a simple way to manage your containers. In this guide, we will walk through the steps to install and use Podman on Rocky Linux 8.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo dnf update -y

Step 2: Install Podman

Install Podman using the following command:

sudo dnf install -y podman

Step 3: Verify Podman Installation

To confirm that Podman is installed successfully, check the version:

podman --version

You should see the installed version of Podman displayed.

Step 4: Running Your First Container

Podman uses the same command syntax as Docker. To run your first container, use the following command:

podman run -d --name my-nginx -p 8080:80 nginx

This command pulls the Nginx image from the container registry and runs it in detached mode.

Step 5: Accessing the Nginx Container

You can access the Nginx container by opening your web browser and navigating to:

http://localhost:8080

Step 6: Managing Containers

To list all running containers, use:

podman ps

To stop a container, use:

podman stop my-nginx

To remove a container, use:

podman rm my-nginx

Step 7: Working with Images

To list available images, use:

podman images

To pull an image from a registry, use:

podman pull alpine

Step 8: Running Podman as a Non-Root User (Optional)

Podman can be run as a non-root user. To do this, simply use the Podman commands without sudo.
