K8S学习之基础十五：k8s中Deployment扩容缩容

deployment扩容缩容比较简单，下面介绍两种常用方法

vi deploy-demo.yaml
kind: Deployment
metadata:
  name: myapp-v1
spec:
  replicas: 2
  selector:
    matchLabels:
      app: myapp
      version: v1
  template:
    metadata:
      labels:
        app: myapp
        version: v1
    spec:
      containers:
      - name: myapp
        image: 172.16.80.140/myapp/myapp:v1
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80

第一种方法：修改yaml中replicas的值，应用该yaml，如replicas: 3

第二种方法：kubectl edit deploy myapp-v1，修改replicas: 4，保存查看

缩容和扩容一样操作
