ctr [global options] command [arguments]

ctr is the command-line client for containerd, the industry-standard container runtime. It provides low-level container and image management capabilities.
Unlike Docker CLI, ctr is designed for debugging and direct containerd interaction rather than general use. Kubernetes typically uses containerd through crictl instead.

Low-level tool primarily for debugging. For Kubernetes environments, use crictl. For general Docker-like experience, use nerdctl. Requires root or containerd socket access.
