k8s pod 如何删除

在k8s 里面如果直接删除pod,, 是起不到作用的,因为删除的pod 还是被继续拉起来。

看下面的例子,我们把 deployment-ngx-8ff559dc9-5v5f7 这个pod 通过kubectl  delete pod 的方式删除掉

 

[root@k8s-master ~]# kubectl get pods
NAME                             READY   STATUS    RESTARTS   AGE
deployment-ngx-8ff559dc9-5v5f7   1/1     Running   0          10m
deployment-ngx-8ff559dc9-xcskd   1/1     Running   0          10m
test                             1/1     Running   0          22h
test-nginx                       1/1     Running   0          22h
[root@k8s-master ~]# kubectl delete deployment-ngx-8ff559dc9-5v5f7
error: the server doesn't have a resource type "deployment-ngx-8ff559dc9-5v5f7"
[root@k8s-master ~]# kubectl delete pod deployment-ngx-8ff559dc9-5v5f7
pod "deployment-ngx-8ff559dc9-5v5f7" deleted
[root@k8s-master ~]# kubectl get pods -o wide
NAME                             READY   STATUS              RESTARTS   AGE   IP               NODE        NOMINATED NODE   READINESS GATES
deployment-ngx-8ff559dc9-br8ww   0/1     ContainerCreating   0          15s   <none>           k8s-node1   <none>           <none>
deployment-ngx-8ff559dc9-xcskd   1/1     Running             0          10m   10.244.36.74     k8s-node1   <none>           <none>
test                             1/1     Running             0          22h   10.244.36.68     k8s-node1   <none>           <none>
test-nginx                       1/1     Running             0          22h   10.244.169.131   k8s-node2   <none>           <none>

  

但是又立马重启了一个新的同类型的pod。

是因为deployment 控制replicasSet,, 当副本数跟实际的不相符的时候,rs 会自动再创建新的,直到跟模板上的一致

 

那么问题来了,要想删除pod 该怎么办呢

其实通过删除deployment,, 然后机会自动删除pod 

[root@k8s-master ~]# kubectl delete deployment deployment-ngx
deployment.apps "deployment-ngx" deleted
[root@k8s-master ~]# kubectl get deployment
No resources found in default namespace.
[root@k8s-master ~]# kubectl get pods
NAME                             READY   STATUS        RESTARTS   AGE
deployment-ngx-8ff559dc9-br8ww   0/1     Terminating   0          6m10s
deployment-ngx-8ff559dc9-xcskd   0/1     Terminating   0          16m
test                             1/1     Running       0          22h
test-nginx                       1/1     Running       0          22h
