How to Use Different Container Runtimes: Docker, Podman, and Containerd Explained
A practical comparison of three container runtimes — Docker, Podman, and containerd — covering installation, core commands, and real-world use cases. Docker serves as the familiar baseline; Podman offers a daemonless, rootless alternative with native pod support and Kubernetes YAML generation; containerd provides the smallest footprint for edge and production Kubernetes environments. All three runtimes follow OCI standards, making images fully portable across them via registries or tar export/import. Includes a command reference table and guidance on when to choose each runtime.
