containerd

Use this skill to manage containers and images using containerd's CLI tools safely and effectively.

Quick Start

1. Run ctr version to verify containerd is running and accessible.
2. Use nerdctl for Docker-compatible container operations — it supports the same flags.
3. Use ctr only for low-level debugging; it bypasses higher-level abstractions.
4. Inspect /etc/containerd/config.toml before modifying; back it up first.

Intent Router

• references/install-and-setup.md — install containerd, nerdctl, CNI plugins, BuildKit
• references/command-cookbook.md — nerdctl and ctr commands for containers, images, tasks
• references/containerd-config.md — config.toml structure, CRI plugin, snapshotters, registry mirrors
• references/kubernetes-integration.md — containerd as Kubernetes CRI, crictl debugging, image GC
