ingress配置

案例1

cat << EOF > http.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: httpd-test
spec:
  rules:
  - host: foo.bar.com
    http:
      paths:
      - backend:
          serviceName: httpd
          servicePort: 80
  - host: bar.baz.com
    http:
      paths:
      - backend:
          serviceName: nginx
          servicePort: 80
EOF



案例2


cat << EOF> https.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: https-test
spec:
  tls:
  - hosts:
    - www.aliangedu.com
    secretName: aliangedu-https
  rules:
  - host: www.aliangedu.com
    http:
      paths:
      - backend:
          serviceName: nginx
          servicePort: 80
EOF




实战案例3：
cat << EOF > nginx-deployment.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: hpanginx-deployment
  labels:
    app: hpanginx
spec:
  replicas: 4
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app: hpanginx
  template:
    metadata:
      labels:
        app: hpanginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80
        resources:
          requests:
            memory: "64Mi"
            cpu: "25m"
          limits:
            memory: "128Mi"
            cpu: "50m"
---
kind: Service
apiVersion: v1
metadata:
  labels:
    app: hpanginx
  name: nginx-deployment-service
spec:
  ports:
    - port: 80
      targetPort: 80
      name: http
  selector:
    app: hpanginx

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-deployment-service-ingress
spec:
  rules:
    - host: nginx-deployment.chenlei.com
      http:
        paths:
          - backend:
              serviceName: nginx-deployment-service
              servicePort: 80
EOF



注意：每一个节点都要有nginx-ingress-controller，例如有三个节点，

但kubectl get po -o wide -n ingress-nginx | grep controller 查看只有两个nginx-ingress-controller，则用下面命令扩充

kubectl scale --replicas=3 deploy/nginx-ingress-controller -n ingress-nginx
