kubernetes如何快速编写yaml文件

有两种方式

1、使用kubectl create命令生成yaml

[root@test yaml]# kubectl create deployment my-dep --image=nginx -o yaml --dry-run >web.yaml
W1214 12:23:36.642511    6822 helpers.go:553] --dry-run is deprecated and can be replaced with --dry-run=client.
[root@mvpemen-game--test yaml]# cat web.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: my-dep
  name: my-dep
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-dep
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: my-dep
    spec:
      containers:
      - image: nginx
        name: nginx
        resources: {}
status: {}

2、将部署好的医院使用kubectl get命令导出yaml文件

[root@test yaml]# kubectl get deployment my-dep -o yaml  >my2.yaml
[root@test yaml]# cat my2.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  annotations:
    deployment.kubernetes.io/revision: "1"
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"apps/v1","kind":"Deployment","metadata":{"annotations":{},"creationTimestamp":null,"labels":{"app":"my-dep"},"name":"my-dep","namespace":"default"},"spec":{"replicas":1,"selector":{"matchLabels":{"app":"my-dep"}},"strategy":{},"template":{"metadata":{"creationTimestamp":null,"labels":{"app":"my-dep"}},"spec":{"containers":[{"image":"nginx","name":"nginx","resources":{}}]}}},"status":{}}

    app: my-dep
