CO containerd vs PO Podman

containerd is an industry-standard container runtime that manages the complete container lifecycle. It is the runtime used by Docker, Kubernetes (as the CRI), and most container orchestration platforms. Designed for embeddability and minimalism — not meant for direct end-user interaction but as infrastructure for higher-level tools.

Podman is a daemonless container engine by Red Hat that provides a Docker-compatible CLI for building, running, and managing OCI containers. Key differentiator: rootless by default (better security). Supports pods (K8s-like multi-container groups), podman machine for macOS/Windows, and integrates with systemd. A drop-in Docker replacement for most workflows.
