使用入口控制器公开kubernetes部署（前端）

Question

apiVersion: extensions/v1beta1
kind: Ingress

apiVersion: v1
kind: Service
metadata:
  annotations:
    service.beta.kubernetes.io/azure-load-balancer-resource-group: my-resource-group
  name: myapp-svc
  namespace: ui
spec:
  loadBalancerIP: SOME_IP_ADDRESS
  type: LoadBalancer
  ports:
  - port: 80
 selector:
   app: myapp

如何使用入口控制器本身公开UI而不创建外部LoadBalancer？

Answer 1

试着这样-

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    nginx.ingress.kubernetes.io/service-upstream: "true"
  name: rule-name
  namespace: default
spec:
  rules:
  - host: hostname
    http:
      paths:
      - backend:
          serviceName: frontend-service
          servicePort: port-number
        path: /(.*)
      - backend:
          serviceName: backend-service
          servicePort: port-number
        path: /api/(.*)

您可以使用上面定义的策略，直接在/处映射前端，并使用rewrite-target将主机名/API之类的内容映射到后端服务。

只能将前端和后端服务保留在clusterIP级别
