查看运行中pod，并运行一个容器

[root@mast-1 k8s]# kubectl get pods
No resources found.
[root@mast-1 k8s]# kubectl run nginx --image=nginx   运行nginx容器
kubectl run --generator=deployment/apps.v1beta1 is DEPRECATED and will be removed i
n a future version. Use kubectl create instead.deployment.apps/nginx created
[root@mast-1 k8s]# kubectl get pods
