Why Are Developers Moving from Docker to Podman and How to Use It?

Introduction

Container technology has become a core part of modern cloud computing, DevOps workflows, and microservices architecture. For many years Docker was the most popular container platform used by developers and organizations. However, in recent years many developers, especially in cloud-native environments and enterprise Linux systems, have started moving from Docker to Podman. Podman provides a daemonless container engine, stronger security features, and better integration with Kubernetes and modern infrastructure tools. In this article we will explore why developers are shifting from Docker to Podman and how beginners can start using Podman for containerized applications.

Understanding Docker and Podman

Docker is a container platform that allows developers to package applications and their dependencies into containers. These containers can run consistently across development, testing, and production environments.

Podman is an open-source container engine developed by Red Hat that allows users to run containers and manage container images. Podman is compatible with Docker commands and container images, which means developers can transition easily without rewriting their container workflows.

Key Reasons Developers Are Moving from Docker to Podman

One major reason developers are adopting Podman is its daemonless architecture. Docker relies on a central daemon that manages all containers. If the Docker daemon fails or becomes compromised, it can affect all running containers. Podman removes this dependency by allowing containers to run directly under the user process.

Another important advantage is improved security. Podman supports rootless containers, meaning containers can run without root privileges. This significantly reduces security risks in production environments and cloud infrastructure.

Podman also integrates well with Kubernetes. Developers can generate Kubernetes YAML files directly from Podman containers, making it easier to move containerized applications to Kubernetes clusters.

In enterprise environments where Red Hat Enterprise Linux or Fedora is used, Podman is often the default container engine, which further encourages adoption.

Docker vs Podman Comparison

Feature	Docker	Podman
Architecture	Uses central daemon	Daemonless architecture
Security	Typically requires root	Supports rootless containers
Kubernetes integration	Requires additional tools	Built-in Kubernetes support
CLI compatibility	Standard Docker CLI	Docker compatible commands

Installing Podman

Podman can be installed on Linux, Windows, and macOS. On most Linux systems the installation process is simple.

Example installation on Ubuntu:

sudo apt update
sudo apt install podman

After installation, verify the version:

podman --version

Running Your First Container Using Podman

Running containers with Podman is very similar to Docker commands.

Example:

podman run hello-world

This command pulls the hello-world container image and runs it.

You can also run an Nginx web server container.

podman run -d -p 8080:80 nginx

After running the container, open the browser and visit localhost:8080 to see the Nginx web server running.

Managing Containers

Podman provides commands to manage containers and images.

List running containers:

podman ps

Stop container:

podman stop container_id

Remove container:

podman rm container_id

These commands are similar to Docker, which makes migration easier for developers.

When Should You Use Podman?

Podman is ideal for cloud-native applications, secure container environments, Kubernetes development, and enterprise Linux infrastructure. Developers working with CI/CD pipelines, DevOps automation, and container orchestration often prefer Podman because of its security and flexibility.

Summary

Podman is becoming a popular alternative to Docker because it offers a daemonless architecture, improved security through rootless containers, and seamless compatibility with Kubernetes and modern DevOps workflows. Since Podman supports Docker-compatible commands and container images, developers can transition easily without major changes to their existing container workflows. As organizations adopt cloud-native infrastructure and stronger security practices, Podman is emerging as a powerful container engine for building, running, and managing containerized applications.
