What is Podman and how to use Podman?

Dear friends, in this blog we will see What is Podman and how to use Podman? In the world of containerization and orchestration, Kubernetes has undoubtedly emerged as the dominant player. Its flexibility and robustness have revolutionized how we deploy and manage applications at scale. While Kubernetes primarily relies on Docker as the container runtime, an alternative tool called Podman has been gaining popularity as a more secure and lightweight alternative.

What is Podman?

Podman is an open-source container management tool developed by Red Hat. It provides a Docker-compatible command-line interface for creating, managing, and running containers and pods, similar to what Docker does. However, what sets Podman apart is its ability to run containers as non-privileged users, which enhances security and eliminates the need for a daemon, making it a more lightweight solution.

How to install Podman in kubernetes?

To start using Podman in your Kubernetes environment, you’ll first need to install it on your machine. The installation process may vary depending on your operating system, but generally, it involves downloading the appropriate binaries or using package managers like apt or yum. Make sure you have the latest version of it to access all the latest features and bug fixes.

Running Standalone Containers with Podman: –

The basic usage of Podman closely resembles that of Docker. To run a single container, use the podman run command, followed by the container image name. For instance:

podman run -d --name my_container nginx

This command will pull the nginx image from a container registry if it’s not already available on your system, create a new container named my_container, and run the Nginx web server within the container.

Managing Pods with Podman: –

Kubernetes organizes containers into pods, and Podman allows you to manage pods as well. Unlike Docker, where you run individual containers, This lets you work with groups of containers using the concept of pods. To create a pod with multiple containers, use the podman pod create command:

podman pod create --name my_pod

After creating the pod, you can add containers to it:


In this example, we created a pod named my_pod and added two containers to it—one running Nginx and the other running a simple BusyBox container that does nothing but sleep indefinitely.

Kubernetes Integration:

To use Podman in Kubernetes, you can take advantage of the Container Runtime Interface (CRI) compatibility that Podman provides. Kubernetes has a CRI implementation that allows it to communicate with container runtimes. It can act as a CRI implementation, enabling you to run and manage containers within Kubernetes without using Docker.

To set up Podman as the container runtime for Kubernetes, you need to configure the kubelet to use the CRI-O runtime. The kubelet is the primary node agent responsible for managing the state of nodes and ensuring that containers are running. With it acting as the CRI-O runtime, Kubernetes can seamlessly interact with Podman-managed containers.

Podman is a powerful alternative to Docker for container management, especially when security and resource constraints are a concern. Its compatibility with Kubernetes through the CRI interface makes it an excellent choice for running containers within Kubernetes clusters. By following the steps mentioned above, you can easily start using it in your Kubernetes environment and take advantage of its features to streamline container management and enhance security.

Remember to stay updated with Podman’s latest releases and features, as the container ecosystem continues to evolve. Happy containerizing with Podman in Kubernetes!
