Question

从昨天开始，我在使用GKE的K8上遇到一个奇怪的错误

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，副本集不会被删除，因此pod继续运行。

其他人有这个问题吗？还是知道解决此问题的方法？

是否应该在删除部署之前将其副本数减少到0？或其他解决方案？

我正在使用v1.15.9-gke.24

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:

      containers:

            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，没有立即从kubectl -n default delete deployment dummy-deployment创建日志

创建部署后立即

从kubectl get events发送日志

如果您只想简单删除，请尝试使用

kubectl delete -f dummy_deployment.yaml

kubectl delete -f dummy_serviceaccount.yaml

最佳实践是使用创建对象的文件删除Kubernetes对象以进行完全删除。另外，尝试在名称空间内创建对象，以使进程保持隔离。因此，您可以进行kubectl delete namespace test-ns并省去了删除实体的麻烦。

通过(--v=6 or --v=9)或--v=6标志，您总是可以得到更高的详细程度--v=9，以删除所有内容，并以哪种方式删除

kubectl delete deployment dummy-deployment --v=6

但是，这不是预期的行为，群集资源删除一定有问题。对于天蓝色的PVC来说，删除它会花费太多时间。

GKE删除部署不会删除副本集
