部署deployment和service

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: web
  name: web
  namespace: dalong
spec:
  replicas: 2
  selector:
    matchLabels:
      app: web
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
    spec:
      containers:
      - image: nginx:1.18
        imagePullPolicy: Always
        name: web
        resources: {}
---
apiVersion: v1
kind: Service
metadata:
  name: web
  namespace: dalong
spec:
  ports:
  - port: 80
    protocol: TCP
    targetPort: 80
  selector:
    app: web
  type: NodePort

ingress.yaml如下，画红线部分一定要加

在另一台机器上配置host

//下面这行配置在hosts文件中 192.168.37.131即worker1   的ip
//通过 kubectl get pod -n  ingress-nginx -o wide，查看pod所在的主机ip即worker1
192.168.37.131  app.dalong.com  



[root@k8s-worker01 tmpdir]# kubectl get pod -n  ingress-nginx -o wide
