StatefulSets | Kubernetes

StatefulSets currently require a Headless Service to be responsible for the network identity of the Pods. You are responsible for creating this Service.

Pod Identity

StatefulSet Pods have a unique identity that is comprised of an ordinal, a stable network identity, and stable storage. The identity sticks to the Pod, regardless of which node it’s (re)scheduled on.

• helm ne supprime pas les pvc des statefulset
• high availability peer-to-peer system from the point of view of the public network
• pvc gérés par un statefulset sont persistés par helm delete alors que supprimés si par deployment
