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
