GKE入侵域无法在一个主机下路由多条路径

Question

我无法在- host: api.mysite.com下找到任何一条与GKE大会一起工作的路径，我不明白为什么。当我尝试这些路线时，我得到404。

通过下面的示例，我希望api.mysite.com/v1/和api.mysite.com/v2/能够路由到适当的服务(我通过nodeport公开了这些服务)。不幸的是，我只得到404的回报。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: gce-ingress
  namespace: default
  annotations:
    kubernetes.io/ingress.global-static-ip-name: my-global-ip
spec:
  rules:
  - host: mysite.com
    http:
      paths:
      - backend:
        serviceName: webserver
        servicePort: 8080
  - host: www.mysite.com
    http:
      paths:
      - backend:
        serviceName: webserver
        servicePort: 8080
  - host: api.mysite.com
    http:
      paths:
      - path: /v2/*
        backend:
          serviceName: api-v2
          servicePort: 9000
      - path: /v1/*
        backend:
          serviceName: api-v1
          servicePort: 8000

公开服务的节点：

apiVersion: v1
kind: Service
metadata:
  name: webserver
  labels:
    app: webserver
  namespace: default
spec:
  selector:
    app: webserver
  type: NodePort
  ports:
  - port: 8080
    name: http
    protocol: TCP
    targetPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: api-v2
  labels:
    app: api-v2
  namespace: default
spec:
  selector:
    app: api-v2
  type: NodePort
  ports:
  - port: 9000
    name: http
    protocol: TCP
    targetPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: api-v1
  labels:
    app: api-v1
  namespace: default
spec:
  selector:
    app: api-v1
  type: NodePort
  ports:
  - port: 8000
    name: http
    protocol: TCP
    targetPort: 8080

当我测试入口(真实主机名和ip被编辑)时的结果：

Answer 1

为了重现这个问题，我遵循了下面的文档，该文档解释了如何设置HTTP负载平衡，然后作为一个可选的东西，您可以保留一个静态IP地址，并在同一个负载均衡器上为多个应用程序提供服务。

按照上面的URL一步一步地操作对我来说很好：

希望它对你有用。
