在Kubernetes集群中使用Redis部署PHP留言簿应用程序(5)

[root@aniu-k8s guestbook]# kubectl scale deployment frontend --replicas=2
deployment "frontend" scaled
[root@aniu-k8s guestbook]# kubectl get pods
NAME                            READY    STATUS        RESTARTS  AGE

清理pods及services

删除部署和服务也会删除任何正在运行的Pod。使用标签可以用一个命令删除多个资源。

运行以下命令删除所有Pod，Deployments和Services。

kubectl delete deployment -l app=redis
kubectl delete service -l app=redis
kubectl delete deployment -l app=guestbook
kubectl delete service -l app=guestbook

回显如下：

deployment "redis-master" deleted
deployment "redis-slave" deleted
service "redis-master" deleted
service "redis-slave" deleted
deployment "frontend" deleted   
service "frontend" deleted

查询Pod的列表以验证没有Pod正在运行：

kubectl get pods
#
No resources found.
