Podman

Podman is a daemonless container engine for developing, managing, and running OCI Containers. It is a drop-in replacement for Docker (alias docker=podman). Podman v5 (2025) features a rewritten hypervisor support for Mac/Windows.

When to Use

• Security: Rootless containers by default. No central daemon running as root.
• HPC / Restricted Env: Run containers on systems where you don't have root access.
• Kubernetes: Generating K8s YAML from running containers (podman kube generate).

Quick Start

# Run a container (Rootless)
podman run -dt -p 8080:80 nginx

# Generate K8s YAML
podman kube generate my-container > pod.yaml
