ingress

1.下载

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.2.0/deploy/static/provider/cloud/deploy.yaml

2.在所有node节点，拉镜像

crictl pull dyrnq/controller:v1.2.0

3.修改deploy.yaml

将image: k8s.gcr.io/ingress-nginx/controller:v1.2.0@sha256:d8196e3bc1e72547c5dec66d6556c0ff92a23f6d0919b206be170bc90d5f9185

image: k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660

image: k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660

改为

image: docker.io/dyrnq/controller:v1.2.0@sha256:d8196e3bc1e72547c5dec66d6556c0ff92a23f6d0919b206be170bc90d5f9185

image: registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660

image: registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660

4.允许ingress

 kubectl apply -f deploy.yaml 

5.查看ingress-nginx的pod和service

kubectl get pods -n ingress-nginx 
kubectl get svc  -n ingress-nginx

6.创建nginx tomcat pod
kubectl create namespace dev
vim nginx-tomcat-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  namespace: dev
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx-pod
  template:
    metadata:
      labels:
        app: nginx-pod
    spec:
      containers:
        - name: nginx-container
          image: nginx:latest
          ports:
            - name: nginx-port
              containerPort: 80
              protocol: TCP

---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: tomcat-deployment
  namespace: dev
spec:
  replicas: 3
  selector:
    matchLabels:
      app: tomcat-pod
  template:
    metadata:
      labels:
        app: tomcat-pod
    spec:
      containers:
        - name: tomcat-container
          image: tomcat:8.5-jre10-slim
          ports:
            - name: tomcat-port
              containerPort: 8080
              protocol: TCP

kubectl apply -f nginx-tomcat-deployment.yaml

7.创建nginx,pod service
vim nginx-tomcat-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  namespace: dev
spec:
  selector:
    app: nginx-pod
  type: ClusterIP
  clusterIP: None
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80

---


apiVersion: v1
kind: Service
metadata:
  name: tomcat-service
  namespace: dev
spec:
  selector:
    app: tomcat-pod
  type: ClusterIP
  clusterIP: None
  ports:
    - protocol: TCP
      port: 8080
      targetPort: 8080

kubectl apply -f nginx-tomcat-service.yaml

8.新建ingress-http.yaml文件
vim ingress-http.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-http
  namespace: dev
spec:
  rules:
    - host: nginx.bulut.com
      http:
        paths:
          - path: /
            pathType: Exact
            backend:
              service:
                name: nginx-service
                port:
                  number: 80  
    - host: tomcat.bulut.com
      http:
        paths:
          - path: /
            pathType: Exact
            backend:
              service:
                name: tomcat-service
                port:
                  number: 8080
  ingressClassName: nginx

kubectl apply -f ingress-http.yaml
kubectl get ingress ingress-http -n dev

本地kubesphere不会手动创建，一定要注意！！

9.本次设置host文件后访问
