GKE删除部署不会删除副本集

Question

从昨天开始，我在使用GKE的K8上遇到奇怪的错误

我有一个正在运行1个Pod的部署。我删除了部署，它用于终止pod和副本集。

但是现在，如果我删除部署，则不会删除副本集，因此pod继续运行。

其他人还有这个问题吗？还是知道解决此问题的方法？

在删除部署之前，应将我的部署的副本数减少到0吗？或其他解决方案？

我正在使用v1.15.9-gke.24

复制的虚拟示例

dummy_deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: dummy-deployment
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      name: dummy
  template:
    metadata:
      labels:
        name: dummy
    spec:
      serviceAccountName: dummy-serviceaccount
      nodeSelector:
        cloud.google.com/gke-nodepool : default-pool
      containers:
      - name: pause
        image: gcr.io/google_containers/pause
        resources:
          limits:
            memory: 100M
          requests:
            cpu: 100m
            memory: 100M

dummy_serviceaccount.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: dummy-serviceaccount
  namespace: default

我运行的命令

kubectl apply -f dummy_serviceaccount.yaml
kubectl apply -f dummy_deployment.yaml

kubectl -n default get pods | grep dummy

kubectl delete deployments dummy-deployment

kubectl -n default get pods | grep dummy
kubectl -n default get replicasets | grep dummy

有趣的观察

deployment.extensions "dummy-deployment" deleted

deployment.apps/dummy-deployment created

[使用kubectl apply创建新部署时，将创建deployment.apps。但是，当使用kubectl delete删除部署时，deployment.extensions被删除。

使用kubectl get events删除部署后立即从kubectl -n default delete deployment dummy-deployment创建的无日志

创建展开后立即从kubectl get events发送日志
