Kubernetes Ingress 不工作：默认后端 404

Question

我是 Kubernertes 的新手，我们有一个可以为多个客户定制的应用程序。

部署很好：它们运行 pods 正确。问题是访问集群外的API

正在按 Kubernetes Ingress 的预期创建 AWS 路由。

现有的工作正常，但当我尝试到达新的（假设 client09）时，总是 return default-backend-404.

此外，当 curl url 时，它会显示一条 Kubernetes Ingress Controller Fake Certificate 消息。

kubectl 版本客户端 1.6 服务器 1.9

另外，我的用户没有完全访问权限，因此我无法提供有关 nginx controller 的任何信息。我们只是为新客户提供相同的粘贴和复制，但不知道哪里出了问题。

有什么想法吗？

选择器似乎有问题。您能否将服务 YAML 更新为：

apiVersion: v1
kind: Service
metadata:
 name: client09-svc
 labels:
   run: client09-deploy
 spec:
   type: ClusterIP
   ports:
     - port: 8080
       targetPort: 8080
       protocol: TCP
       name: api
   selector:
     name: client09-deploy
