Who's Running My Pods? A Deep Dive into the K8s Container Runtime Interface

on YouTube ↗35m

" summary

Kubernetes relies on a CRI plugin to run containers and this demo maps kubectl -> crictl -> ctr to the live process: a Kubernetes 1.11 cluster on IBM Cloud (Dallas) with containerd 1.1.4 shows an nginx pod, the container appears in crictl and ctr, and the container PID matches the nginx process. containerd runs continuous stress tests (millions of containers weekly) and CRI integration is declared GA, and killing a container triggers kubelet restart of the container.
