我们在AWS上运行Kubernetes集群。
当我尝试删除Deployment时-副本集也会被删除-但Pod仍保留，不会被删除。
当我重新部署时，我会得到一个新的部署，新的副本集和一个新的pod（所以现在有2个可用的...）

apiVersion: v1
kind: Service
metadata:
  name: helloworld
  labels:
    app: helloworld
spec:
  ports:
    - 
      port: 80
      targetPort: 10000
  selector:
    service: helloworld
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: helloworld
spec:
  replicas: 1
  revisionHistoryLimit: 0
  selector:
    matchLabels:
      service: helloworld
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
    type: RollingUpdate
  template:
    metadata:
      labels:
        service: helloworld
    spec:
      containers:

        name: helloworld
        image: 'my.service.io/service/helloworld:latest'
        imagePullPolicy: Always
        ports:
        - containerPort: 10000
        command:
        - node
        args:
        - "app.js"
      imagePullSecrets:
      - name: my-screts
      restartPolicy: Always
      terminationGracePeriodSeconds: 30

为什么在删除部署集和副本集时未删除pod？
