Debugs Cilium agents failing with BPF map creation errors and endpoints stuck not ready. Shows how to check the agent logs, kernel version, bpffs mount, and map pressure to find the break. Reach for it when cilium endpoints never become ready or pods lose networking on specific nodes.
Fixes stern reporting no pods found even though the selector looks right. Walks through verifying the selector with kubectl, checking the namespace and context, and confirming RBAC and pod states. Reach for it when stern finds nothing but you know the pods exist.
Debugs pod evictions caused by the node.kubernetes.io/unreachable NoExecute taint. Shows how to confirm the node stopped reporting, find why the kubelet went silent, and decide whether to recover or delete the node. Reach for it when pods get evicted after a node goes NotReady.

Fixes Kubernetes API 429 Too Many Requests errors caused by client-side throttling. Shows how to identify the hot client from audit logs, then raise its QPS and burst settings or reduce request churn. Reach for it when controllers or automation start failing with 429s under load.
Tracks down which admission webhook rejected a pod and why. Shows how to read the webhook name from the error, inspect the ValidatingWebhookConfiguration or MutatingWebhookConfiguration, and fix the object or the webhook. Reach for it when applies are rejected with a webhook denial.

Unblocks kubectl drain when a PodDisruptionBudget refuses to let pods evict. Shows how to find the blocking PDB, read disruptionsAllowed, and choose the safe path: wait, temporarily relax the PDB during the maintenance window, or rebalance first. Reach for it whenever a drain aborts on PDB protection.
Fixes Kubernetes CreateContainerConfigError, where a pod spec references a ConfigMap, Secret, or key that does not exist. Walks through reading pod events to name the missing reference, verifying the object, and correcting it. Reach for it when a pod never starts and describe shows the config error.

Explains the Kubernetes ImageInspectError and how to fix it: verifying the image tag exists, the registry is reachable, and pull credentials are valid. Use it when pod events show ImageInspectError. Not for ImagePullBackOff, where the pull starts but fails.
Explains how to rotate Kubernetes service account tokens so long-lived credentials do not accumulate. Use this when a cluster still uses legacy auto-mounted tokens and you want to move to short-lived, audience-bound tokens. Not for rotating user certificates or cloud IAM roles.
