问题：

Zuul无法将流量路由到kubernetes上的服务

澹台景山
2023-03-14

我们有Zuul和Eureka在我们的kubernetes集群上运行。Zuul在Eureka注册。

我启动了一个名为“资源服务”的新服务，这将正确启动并注册到Eureka，所有服务都启动了。

当我试图访问Zuulendpoint以访问“resource-service”时，我得到以下错误。看起来Zuul不能映射到Resource-service,即使Resource-service注册了Eureka。

Zuul堆栈跟踪（更新）

我认为您注册到Zuul的主机名和在K8S中可以访问的主机名不匹配。使用“kubectl get services”来查找您的k8s服务的名称。Zuul将获得从eureka注册到它的名字（看起来你注册的是名字，而不是IPs）。如果您在k8s yaml中将resource-service的服务名称更改为'resource-service'，那么我希望它能够工作。

在您的docker-compose中，我希望您有一个定义resource-service的部分，它可能被命名为resource-service。k8s的等价物是与该特定部署的POD匹配的服务的名称。

编辑：spring boot应用程序默认情况下会向eureka注册Pod的主机名（如果不使用IP）。因此，要重写它，需要将Eureka.instance.hostName设置为与服务名匹配。
