步骤 根据不同的域名实现虚拟主机

1、创建ingress-vh 虚拟主机文件夹

2、到ingress-vh创建

deployment1.yaml

apiVersion: extensions/v1beta1

kind: Deployment

metadata:

  name: deployment1

spec:

  replicas: 2

  template:

    metadata:

      labels:

        name: nginx

    spec:

      containers:

        - name: nginx

          image: hub.lqz.com/library/nginx:latest

          imagePullPolicy: IfNotPresent

          ports:

            - containerPort: 80

---

apiVersion: v1

kind: Service

metadata:

  name: svc-1

spec:

  ports:

    - port: 80

      targetPort: 80

      protocol: TCP

  selector:

    name: nginx

创建：kubectl apply -f deployment1.yaml

查看：kubectl get svc

连接测试：curl ****

复制成第二个dployment

cp -a deployment1yaml  deployment2.yaml

第二个deployment

deployment2.yaml

apiVersion: extensions/v1beta1

kind: Deployment

metadata:

  name: deployment2

spec:

  replicas: 2

  template:

    metadata:

      labels:

        name: nginx2  #name标签不能一致

    spec:

      containers:

        - name: nginx2

          image: hub.lqz.com/library/nginx:v2

          imagePullPolicy: IfNotPresent

          ports:

            - containerPort: 80

---

apiVersion: v1

kind: Service

metadata:

  name: svc-2

spec:

  ports:

    - port: 80

      targetPort: 80

      protocol: TCP

  selector:

    name: nginx2

vim ingressrule.yaml  多个yaml文件可以写在一起，中间通过---隔开即可

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

   name:ingress1

spec:

 rules:

   - host: www1.atguigu.com

     http:

       paths:

       - path: /

         backend:

           serviceName: svc-1

           servicePort: 80

---

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

   name:ingress2

spec:

 rules:

   - host: www2.atguigu.com

     http:

       paths:

       - path: /

         backend:

           serviceName: svc-2

           servicePort: 80

运行ingressrule.yaml：kubectl apply -f ingressrule.yaml

查看：kubect get pod -n ingress-nginx

进入 ingress容器查看：

kubectl exec 容器名 -n ingress-nginx -it -- /bin/bash

查看

cat nginx.conf

kubectl get ingress
