OpenShift - 路由未连接到 pod

Question

我目前有问题暴露在openshift 4环境中运行的pod。尝试连接https://route...导致503.

kind: Route
apiVersion: route.openshift.io/v1

我有一个完全相同的设置运行端口8080的春季启动应用程序，这工作得很好!

我肯定豆荚是活的，当连接到豆荚本身curl localhost:9200工作良好!

有人可以提供一些指针可能是错的，或者我如何能更详细地调查这个问题?!

Answer 1

在您的Route中，port.targetPort应该是8080

https→路线:443→服务:8080→豆荚:9200

Answer 2

在您的服务中，更改spec.ports[0]。端口到9200而不是8080，它应该工作。

Answer 3

显然我的服务和路由配置是正确的。事实上，吊舱在港口没有正常运行…

老实说，我不了解细节，但我不得不改变配置的pod与elasticsearch.yml

http.host: 0.0.0.0
http.port: 8080
transport.tcp.port: 9200
transport.host: localhost

下面的链接帮助了我:

可以't访问端口9200远程
