CKS Series 1.8 – Admission Webhooks & API Server Recovery (ImagePolicy Integration)

In this CKS Series episode, we dive into a full scenario involving Admission Webhooks and cluster troubleshooting.

▶️ In this video:

Set up an ImagePolicyWebhook to block pods from using the latest image tag

Integrate a pre-built admission webhook server (image-bouncer-webhook)

Update the API server admission configuration safely

Troubleshoot a broken API server if it becomes unresponsive

Use critical thinking and log inspection (crictl, logs) to recover cluster services

🔐 Admission control is a crucial part of Kubernetes security — and real-world handling of API server failures is an underrated but essential skill for CKS and production operations.
