summary

containerd exposes five concrete extension points and shows working examples: a custom ECR resolver replaces registry logic in the Go thick client and parallelizes layer fetches; an executable runtime plugin launches Firecracker microVMs via a shim and successfully runs OCI containers inside a VM; a proxy snapshotter implements copy‑on‑write as a device‑mapper snapshotter; dynamic Go plugins prove brittle, so a compiled firecracker-containerd binary bundles the plugin. the demo pulls an image and runs it inside a microVM end‑to‑end.
