Rolling Restart — Certified Kubernetes Administrator (CKA) Practice Questions

A rolling restart in Kubernetes allows you to restart all pods in a Deployment without downtime by cycling them one at a time according to the deployment's update strategy. This technique is commonly used to force pods to pick up new ConfigMap or Secret values, or to clear a bad application state without modifying the deployment spec. The CKA exam expects you to know how to trigger and monitor a rolling restart using kubectl and how to configure maxUnavailable and maxSurge to control the rollout pace. Understanding rollout history and the ability to roll back are closely related skills.
