1、查看selector的app为：nginx1

MacBook-Air:test chenfenli$ kubectl get deployment -o wide
NAME         READY   UP-TO-DATE   AVAILABLE   AGE    CONTAINERS   IMAGES          SELECTOR
nginx-dm-1   3/3     3            3           6h8m   nginx        test/nginx:v2   app=nginx1
MacBook-Air:test chenfenli$

2、编写yml：k8s_nginx_svc.yml

apiVersion: v1
kind: Service
metadata:
  name: nginx1-svc
spec:
  type: NodePort
  ports:
    - port: 80
      nodePort: 30001
  selector:
    app: nginx1

3、创建容器

MacBook-Air:test chenfenli$ kubectl create -f k8s_nginx_svc.yml
service/nginx1-svc created

// 查看已经将80宽口映射到30001端口上了
MacBook-Air:test chenfenli$ kubectl get svc -o wide
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE   SELECTOR
kubernetes   ClusterIP   10.96.0.1      <none>        443/TCP        34d   <none>
nginx1-svc   NodePort    10.98.45.151   <none>        80:30001/TCP   11s   app=nginx1

4、访问：master_ip:30001
