How To Install Podman on Ubuntu 22.04 LTS
In this tutorial, we will show you how to install Podman on Ubuntu 22.04 LTS. For those of you who didn’t know, Podman is a container tool for virtualizing applications. It was originally developed by Red Hat and originated in the Cri-O project, which develops a lightweight container runtime environment alternative to the Docker runtime environment. Podman distinguishes itself from its competitors by allowing you to run Containers in both root and rootless modes. Additionally, Podman isn’t a running service, meaning that it’s daemons.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Podman on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
Prerequisites
- A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies.
- A
non-root sudo useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install Podman on Ubuntu 22.04 LTS Jammy Jellyfish
Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.
sudo apt update sudo apt upgrade
Step 2. Installing Podman on Ubuntu 22.04.
By default, the Podman is available on Ubuntu 22.04 base repository. Now run the following command below to install the latest version of Podman to your Ubuntu system:
sudo apt install podman
Now check the version of the installed Podman using the following command:
podman -v
You can also see detailed information about Podman with the following command:
podman info
Step 3. Configure Podman Registry.
By default, the Podman registry is not configured to download and install container images from the web, hence we need to do that manually so that we can use popular repositories such as Docker.io, and Fedora:
nano /etc/containers/registries.conf
Add the following lines:
[registries.search] registries=["registry.access.redhat.com", "registry.fedoraproject.org", "docker.io"]
Step 3. How to use Podman.
Just like Docker, we can use the Podman command line to search Images but from different repositories, added in the previous step. You can search for the Podman images in the registries you have specified as:
podman search debian
Next, download the latest Debian image from the internet using the following command:
podman pull debian
If you have downloaded multiple images and now want to see what are the available images on your system, we can list all of them using the given command:
podman images
Additionally, you can view the running containers by using this command:
sudo podman ps -a
You can list all Podman command options with the following command:
podman --help
