无法访问使用nginx ingress的内部负载均衡器上的服务。

Question

我有一个只有私有子网的EKS集群，所以我试图通过在nginx ingress控制器服务中添加这个注释来暴露内部负载平衡器的服务。

service.beta.kubernetes.ioaws-load-balancer-internal: "true"

问题是我无法访问在入口资源中定义的主机名（kibana.com）（使用vpn）。

这是我的代码。

Answer 1

不知道这是否相关，看不到你的服务定义。

试着使用内部负载均衡器，比如下面，用ip地址代替布尔值，而不是ip地址符号

service.beta.kubernetes.io/aws-load-balancer-internal: 0.0.0.0/0
