我无法在 nginx ingress 和 route53 上访问 kibana

Question

我已经在我的 EKS 集群上部署了带有内部负载均衡器和外部 DNS 的 nginx 入口控制器，所以我尝试使用在 route53 上注册的主机名和私有托管区域 (my-hostname.com) 公开 kibana。但是当我使用 vpn 在浏览器上访问它时，它显示无法访问网站。所以我需要知道我做错了什么

这里是所有资源：

我检查了我的私有托管区域的记录集，发现 kibana.my-hostname.com 已添加，但仍然无法访问它。

Answer 1

Route53 将仅响应来自您内部和允许的 VPC 的请求。您无法从您的 VPC 访问该域。

要解决此问题，请将您的区域更改为 public，或使用带有简单 AD 的 VPN 将请求转发到您的私人区域，如 here 所述。
