How to install Podman on Rocky Linux 8 / Alma Linux 8

Podman is a container engine created by Red Hat. It is intended to be a solid alternative to Docker with some interesting additions.

If you want a more precise definition, you can get it from the same website:

Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System.

The open-source project has a great ease of use, which is a great attraction. In addition to this, it is fully compatible with Docker, as their differences are at the technical level and not so much at the user level.

So, how does it differ, and why is it a good idea to use Podman? Because Docker has a unique daemon that with time and usage will grow more and more.

Podman wanted to make it different. It has decentralized the components for container management and thus avoid that widening of the daemon as it happens in Docker.

Let’s get started.

Installing Podman on Rocky Linux 8 / Alma Linux 8

Before starting, connect via SSH to your server and update it.

sudo dnf update

Podman is a creation of Red Hat, which is a company behind CentOS, which in turn is the base of Rocky Linux and Alma Linux. That is why Podman is present in the official repositories of these distributions.

So, the whole process boils down to this command:

sudo dnf install podman
Install Podman on Rocky Linux 8 / Alma Linux 8
Install Podman on Rocky Linux 8 / Alma Linux 8

If you’d like, you can check the installed version with the following command

podman --version

You will get an output similar to this:

Using Podman on the system

Using Podman is quite similar to using Docker. Even the migration is totally transparent.

So if you want to search for images you can use this command:

podman search [search-term]

For example:

podman search ubuntu
Searching for images

And if you would like to download it, you can do it with this command:

podman pull [image]

For example:

podman pull
Trying to pull
Getting image source signatures
Copying blob 405f018f9d1d done  
Copying config 2794180907 done  
Writing manifest to image destination

And check the downloaded images:

podman images
REPOSITORY                TAG         IMAGE ID      CREATED      SIZE  latest      27941809078c  11 days ago  80.3 MB

As you can see, it is quite similar to Docker.
