第十三题：Scale：扩缩容：

---

题目：Scale the deployment webserver to 6 pods

解题思路：

• 纯考kubectl指令，具体参考：
  https://kubernetes.io/docs/reference/kubectl/cheatsheet/

解题步骤：

1. 创建deployments，副本数为3个：

sudo kubectl create -f deploymentTest.yaml -n ns-ehj

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    name: deployment-test
  name: deployment-test
  namespace: ns-ehj
spec:
  replicas: 3
  selector:
    matchLabels:
      name: deployment-test
  template:
    metadata:
      labels:
        name: deployment-test
    spec:
      containers:
      - image: nginx
        name: deployment-nginx

执行结果：

初始化3个pod

2.执行scale指令做扩容：

sudo kubectl scale --replicas=6 deployment/deployment-test -n ns-ehj

扩容结果
