AWS ALB无法解析

所以我有一个EKS集群,并设置了AWS Alb Ingress Controller:

https://github.com/kubernetes-sigs/aws-alb-ingress-controller

我正在尝试在此处设置Grafana,并创建了Ingress,但它似乎根本无法解决。

我有以下Ingress:

$ kubectl describe ingress grafana
Name:             grafana
Namespace:        orbix-mvp
Address:          4ae1e4ba-orbixmvp-grafana-fd7d-993303634.eu-central-1.elb.amazonaws.com

                              /   grafana:80 (<none>)

后端是以下服务:

$ kubectl describe service grafana
Name:                     grafana
Namespace:                orbix-mvp
Labels:                   app=grafana
                          chart=grafana-1.25.1
                          heritage=Tiller
                          release=grafana
Annotations:              <none>

Type:                     NodePort
IP:                       172.20.11.232
Port:                     service  80/TCP

它确实具有适当的端点:

$ kubectl get endpoints | grep grafana
grafana                         10.0.0.180:3000                  46m

广告连播本身本身已正确标记,并且具有正确的IP,即上面的端点:

$ kubectl describe pod grafana-bdc977fd4-ptzhg
Name:               grafana-bdc977fd4-ptzhg
Namespace:          orbix-mvp

我的AWS账户的LoadBalancer列为“活动”,子网与群集位于同一VPC上,安全组由入口控制器生成。

一切似乎都设置正确,但是当我访问LoadBalancer地址时,它只是超时了。

$ kubectl get ingresses
NAME                HOSTS                           ADDRESS                                                                     PORTS   AGE
grafana             grafana-orbix.orbixpay.com      4ae1e4ba-orbixmvp-grafana-fd7d-993303634.eu-central-1.elb.amazonaws.com     80      49m

答案 0 :(得分:1)

我实际上已经弄清楚了-Ingress配置仅允许该域的流量。 排除到负载平衡器地址的流量(我假定默认情况下允许)。

基本上,必须将*允许,以便Load Balancer URL也能正常工作。另外,如果应用程序像我这样重定向到/login,则也需要允许所有路径,因为如果指定的路径仅用于/,则该重定向将不起作用。
