Introduction to Podman

Learn what Podman is, why it's a powerful alternative to Docker, and how it's changing the container landscape.

If you’ve used Docker, you’re already familiar with how containers can revolutionize software development. But Docker isn’t the only option.

Podman offers a secure, daemonless, and rootless alternative — and it’s designed to be a drop-in replacement for Docker in most scenarios.

📦 What You’ll Learn

In this lesson, you’ll:

• Understand what Podman is and how it differs from Docker
• Learn the key benefits of Podman’s design
• Discover how Podman fits into the OCI ecosystem
• See why developers and sysadmins are switching

🔍 Why Podman?

Podman is part of a modern container toolkit built to address many limitations of Docker, including:

• Security: Run containers without needing root privileges
• Daemonless Design: No central daemon means better reliability and auditability
• System Integration: Easily integrate containers with systemd
• Docker Compatibility: Use the same commands and scripts

🧠 A Bit of Background

Podman was created by Red Hat as a more secure and flexible alternative to Docker, and it works well with other tools like:

• Buildah (for image building)
• Skopeo (for image transfer)
• CRI-O (Kubernetes runtime)

Together, these form a robust, modular container toolchain.

✅ Prerequisites

Before you start, you should:

• Be familiar with Docker basics (e.g., docker run, docker build)
• Have a terminal environment ready (Linux, macOS, or WSL)
