Rolling Update — Certified Kubernetes App Developer (CKAD) Practice Questions
A rolling update is the default Deployment update strategy in Kubernetes, which replaces old Pods with new ones incrementally to maintain availability during a release. CKAD candidates must understand how to configure maxSurge and maxUnavailable parameters to control the pace of a rolling update, and how to monitor rollout progress with kubectl rollout status. The exam also tests the ability to pause, resume, and roll back a Deployment, which are all operations tied to the rolling update mechanism.
