§ Overview

About this video

What You'll Learn

  1. Identify an etcd version mismatch and fix it by comparing manifests and binary compatibility.
  2. Track kubelet startup failures caused by invalid flags, then repair node boot by updating config and binaries.
  3. Resolve cluster networking and control-plane blockers by checking NetworkPolicy, PodSecurityPolicy, and missing CoreDNS/control-plane pods.

Dan Finneran joins Rawkode to debug two broken Kubernetes clusters, unpicking an etcd version mismatch, a bad kubelet flag, an etcd "no space" alarm and quota, a block-all NetworkPolicy, and a PodSecurityPolicy affecting static pods.
