K8S - how to separate Pod definition from StatefulSet definition-CodePudding

In the example below, the Pod definition is embedded in the StatefulSet definition. Is there a way to separate the Pod definition to refer to a separately defined Pod definition?

No.

For longer version, here is definition of StatefulSet

CodePudding user response：

If what you are looking for is to split the StatefulSet into multiple manifests - separate for the Pod and PVC, here is what you can do:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: hello-web-disk-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 30Gi

apiVersion: v1
kind: Pod
metadata:
  name: not-a-stateful-set-pod
  labels:
    app: MyApp
spec:
  containers:
    - name: not-a-stateful-set-container
      image: nginx
      ports:
      - containerPort: 80
        name: http
      volumeMounts:
      - name: hello-web-disk
        mountPath: "/var/www/html"
  volumes:
    - name: hello-web-disk
      persistentVolumeClaim:
        claimName: hello-web-disk-pvc
