Intro + Deep Dive: containerd

on YouTube ↗01h 17m

" summary

containerd is a CNCF‑graduated runtime core used in GKE and IBM IKS that exposes a smart client API (ctr) and CRI plugin, runs full test suites on GKE per PR, and structures functionality as small pluggable services: content, snapshotter, image, task and metadata with lease locking for pulls. Extensions use a plugin registry or external proxy plugins; a new v2 shim and namespaces isolate workloads. Live demos show Firecracker and Kata runtimes launched via containerd plugins and working end‑to‑end.
