Kubernetes StatefulSet is an API-object that’s purpose-built to support stateful application components. It creates a set of identically configured Pods from a spec you supply, but each Pod is assigned a non-interchangeable identity. As with all other Kubernetes config, a DaemonSet needs apiVersion, kind, and metadata fields. For general information about working with config files, see running stateless applications and object management using kubectl. The name of a DaemonSet object must be a valid DNS subdomain name. A DaemonSet also needs a .spec section.Stable Network ID. Each Pod in a StatefulSet derives its hostname from the name of the StatefulSet and the ordinal of the Pod. The pattern for the constructed hostname is $ (statefulset name)-$ (ordinal). The example above will create three Pods named web-0,web-1,web-2. A StatefulSet can use a Headless Service to control the …
