containerd Deep Dive
summary
containerd 1.1 exposes a gRPC API, a Prometheus metrics endpoint and a Go client library that can pull images, create transactional snapshots and start runtimes by handing an OCI/runC spec straight through, supporting runc, Kata and gVisor. the content store uses sha256 digests and a metadata store links images, snapshots and mounts; the demo swaps kubelet from Docker to containerd with built‑in CRI and ultimately starts real pods (a flaky live demo but succeeds), showing you can implement a CRI or small image builder with a few lines of code.
