Question

我无法在端口9092上访问kubernetes服务。同一服务也公开了端口29092，因此我可以访问它。麻烦的是，我在Kube内部运行Kafka。我使用docker stack将docker-compose文件中的资源部署到kube上。这样就创建了如下服务：

NAME                        TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                          AGE
broker                      ClusterIP      None             <none>        55555/TCP                        65m
broker-published            LoadBalancer   10.109.34.43     localhost     9092:30229/TCP,29092:32557/TCP   65m

我现在正尝试通过localhost：9092访问Kafka代理，但无法这样做。我可以轻松访问29092。如果我移植了kubectl port-forward service /经纪人发布的9092：9092，我只能访问9092

当我将服务描述为Yaml时，得到以下信息：

apiVersion: v1

    com.docker.stack.namespace: local-kafka
  sessionAffinity: None
  type: LoadBalancer
status:
  loadBalancer:
    ingress:

我做错了什么？

kubernetes服务无法访问多端口服务上的端口
