资源调度 Deployment：创建与配置文件解析
分别是有状态和无状态应用
创建deployment
[root@kubeadm-master1 ~]# kubectl create deploy nginx-deploy --image=nginx:1.7.9
查看 replicaset
[root@kubeadm-master1 ~]# kubectl get replicaset
NAME DESIRED CURRENT READY AGE
nginx-deploy-845964f5bf 1 1 1 2m34s
查看pod
[root@kubeadm-master1 ~]# kubectl get po
