k8s 创建简单的 deploy 和service的yaml文件写法

1、deployment的简单写法：  nginx-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-depoly
  namespace: default
  labels:
    app: nginxapp
spec:
  replicas: 3
  selector:
     matchLabels:
       app: nginxpod
  template:
    metadata:
      labels:
         app: nginxpod
    spec:
     containers:
     - name: nginxpod
       image: nginx:latest
       imagePullPolicy: IfNotPresent
       ports:
       - containerPort: 80

2、写个对应的service文件 nginx-svc.yaml

apiVersion: v1
kind: Service
metadata:
   name: nginx-svc
   namespace: default
   labels:
     app: nginxsvcapp
spec:
  type: ClusterIP
  selector:
    app: nginxpod
  ports:
   - port: 81
     protocol: TCP
     targetPort: 80
