Question

我试图在我的GKE Kubernetes集群中获得Kibana 6.2.4，该集群在www.mydomain.com/kibana下运行，但未成功。不过，我可以使用kubectl proxy和默认的SERVER_BASEPATH完美地运行它。

这是我的Kibana部署，其中删除了SERVER_BASEPATH。

        proxy_redirect                          off;

    }

但是，转到/kibana会得到404。

网页

{
  statusCode: 404,
  error: "Not Found",
  message: "Not Found"
}

我感觉好像缺少SERVER_BASEPATH和/或我的Nginx入口配置的某种设置。

我相信您想要的是入口中的ViewModel注释。

这样nginx.ingress.kubernetes.io/rewrite-target: /块将看起来像这样：

location {}

Kubernetes中具有Nginx Ingress控制器的Kibana
