Question

全部

根据链接-https://rancher.com/docs/rancher/v2.x/en/installation/ha/

，我们在AWS环境中使用RKE安装了Kubernetes。

所有步骤都可以正常工作，并且AWS NLB中的节点运行状况良好。我看不到任何豆荚有任何问题。但是，当我们点击NLB网址-> https://nlburl.amazonaws.com时，会显示错误/消息为“默认后端-404”。当我键入localhost时，在每个节点中键入相同的错误。版本和其他cmd输出如下所示。

关于如何调试和解决问题的想法或意见？

default backend - 404

Answer 1

您看到的404来自集群入口的默认支持。

您错误地访问了Rancher Server URL。尝试https://rancher.mydomain.com

要使其正常运行，要么需要一个指向rancher.mydomain.com指向NLB的CNAME的DNS条目，要么在本地计算机上的/etc/hosts中具有一个相似的条目。

Rancher-AWS，RKE提供默认后端-404错误
