nginx-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 2
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.8
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: "/usr/share/nginx/html"
          name: nginx-vol
      volumes:
      - name: nginx-vol
        emptyDir: {}

执行命令

$ kubectl apply -f nginx-deployment.yaml

查看状态

$ kubectl get pods

这里主要用volumeMounts 和volumes配合，在ningx的的html目录下挂载了空的目录(emptyDir:{})
下一节中，会利用initContainer动态为nginx加载资源文件，模拟在生产环境中发布前端代码
