kubectl apply -f mandatory.yamlkubectl get pod -n ingress-nginx -o wide

创建第一个服务

vim deply_service1.yamlapiVersion: apps/v1kind: Deploymentmetadata:  name: myapp-deploy1  namespace: defaultspec:  replicas: 3  selector:    matchLabels:      app: myapp      release: v1  template:    metadata:      labels:        app: myapp        release: v1        env: test    spec:      containers:      - name: myapp        image: registry.cn-beijing.aliyuncs.com/google_registry/myapp:v1        imagePullPolicy: IfNotPresent        ports:        - name: http          containerPort: 80---apiVersion: v1kind: Servicemetadata:  name: myapp-clusterip1  namespace: defaultspec:  type: ClusterIP  # 默认类型  selector:    app: myapp    release: v1  ports:  - name: http    port: 80    targetPort: 80

kubectl apply -f deply_service1.yaml

kubectl get deploy -o widekubectl get rs -o widekubectl get pod -o wide --show-labelskubectl get svc -o wide curl 10.244.2.***/hostname.html

创建第二个服务

vim deply_service2.yaml apiVersion: apps/v1kind: Deploymentmetadata:  name: myapp-deploy2  namespace: defaultspec:  replicas: 3  selector:    matchLabels:      app: myapp      release: v2  template:    metadata:      labels:        app: myapp        release: v2        env: test    spec:      containers:      - name: myapp        image: registry.cn-beijing.aliyuncs.com/google_registry/myapp:v2        imagePullPolicy: IfNotPresent        ports:        - name: http          containerPort: 80---apiVersion: v1kind: Servicemetadata:  name: myapp-clusterip2  namespace: defaultspec:  type: ClusterIP  # 默认类型  selector:    app: myapp    release: v2  ports:  - name: http    port: 80    targetPort: 80

kubectl apply -f deply_service2.yaml kubectl get pod -o wide --show-labels -l "release=v2"kubectl get svc -o wide

创建ingress外部访问yaml

vim ingress-http.yamlapiVersion: networking.k8s.io/v1beta1kind: Ingressmetadata:  name: nginx-http  namespace: defaultspec:  rules:    - host: test.demo1.com      http:        paths:        - path: /          backend:            serviceName: myapp-clusterip1            servicePort: 80    - host: test.demo2.com      http:        paths:        - path: /          backend:            serviceName: myapp-clusterip2            servicePort: 80

kubectl apply -f ingress-http.yaml kubectl get ingress -o wide

修改windos

C:\WINDOWS\System32\drivers\etc\hosts           （k8s-master的ip）  test.demo1.com  test.demo2.com

浏览器访问test.demo1.com
浏览器访问test.demo2.com
