The article introduces RestartAllContainers, a new alpha feature in Kubernetes v1.35 that enables efficient in-place Pod restarts without deleting and recreating Pods.
•Enabled via the RestartAllContainersOnContainerExits feature gate on API server and kubelet running v1.35+
•In-place restart preserves the Pod's UID, IP address, network namespace, sandbox, devices, and all volumes including emptyDir and PVCs
•When triggered, all containers terminate and the full startup sequence re-runs from init containers, ensuring a clean state
•Primarily targets AI/ML workloads where Pod rescheduling on 1,000-node clusters can waste over $100,000/month in compute resources
•A new Pod condition AllContainersRestarting is added to the Pod status to make the restart process observable
