k8s删除不了pod和service

# 原因

由于k8s的自愈能力，当我们删除一个pod，k8s会自动恢复一个pod 那么我们如何真正的删掉它呢

[root@master ~]# kubectl get pods
NAME                                READY   STATUS    RESTARTS   AGE
nginx-deployment-5d59d67564-6k5t5   1/1     Running   0          30m
nginx-deployment-5d59d67564-b65tc   1/1     Running   0          30m
nginx-deployment-5d59d67564-hxqhd   1/1     Running   0          30m
[root@master ~]# kubectl delete pod nginx-deployment-5d59d67564-6k5t5
pod "nginx-deployment-5d59d67564-6k5t5" deleted
[root@master ~]# kubectl get pods
NAME                                READY   STATUS    RESTARTS   AGE

[root@master ~]# kubectl get deployment

nginx-deployment   3/3     3            3           32m
[root@master ~]# kubectl delete deployment nginx-deployment
deployment.apps "nginx-deployment" deleted
[root@master ~]# kubectl get pods

值得注意的是这样删除相当于删除了容器，而images还存在*

[root@master ~]# kubectl create -f nginx-service.yaml
Error from server (AlreadyExists): error when creating "nginx-service.yaml": services "nginx-service" already exists
[root@master ~]# kubectl get svc
NAME            TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
