Containerd Fundamentals
summary
Explains that containerd is the library Kubernetes and Docker use to manage images, snapshots and runtimes, and shows a hands‑on install inside WSL with two containerd instances and Docker/Moby engine working side‑by‑side. Demonstrates image lazy-loading snapshots that cut startup time and claims 5–10x faster cold starts, shows runtimes calling runC and newer WASI support, details shims as babysitters for running tasks so containers survive containerd upgrades, and exercises the ctr/netctl CLI and namespace isolation — it all runs successfully.
