集群使用资源编排文件yaml文件对资源进行编排，可以使用kubectl create或者kubectl get快速得到资源编排文件。

快速创建一个资源编排文件：

[root@k8smaster ~]# kubectl create deploy web --image nginx -o yaml --dry-run > web.yaml
    W0526 14:17:16.319803   43068 helpers.go:535] --dry-run is deprecated and can be replaced with --dry-run=client.
    [root@k8smaster ~]# ls
    anaconda-ks.cfg  web.yaml
    [root@k8smaster ~]# cat web.yaml
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      creationTimestamp: null
      labels:
        app: web
      name: web
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: web
      strategy: {}
      template:
        metadata:
          creationTimestamp: null
          labels:
            app: web
        spec:
          containers:
          - image: nginx
            name: nginx
            resources: {}
    status: {}

快速导出一个资源编排文件

[root@k8smaster ~]# kubectl get deploy
    NAME    READY   UP-TO-DATE   AVAILABLE   AGE
    nginx   1/1     1            1           160m

[root@k8smaster ~]# kubectl get deploy nginx -o yaml > nginx.yaml
    [root@k8smaster ~]# ls
    anaconda-ks.cfg  nginx.yaml  web.yaml
    [root@k8smaster ~]# cat nginx.yaml
