从 AKS 私有集群通过 Internet 访问 Pod

问题描述

我有一个完全私有的 AKS 集群，我将它设置在一个私有 VNET 上，我通过 Azure Bastion 访问该 VNET 以运行 kubectl 命令。我还设置了一个 DevOps 管道，它使用自托管代理在私有集群上运行命令。我所有的豆荚和入口似乎都运行良好。但是，当我尝试使用主机名（通过映射公共 ip）访问我的入口时，我发现 404 未找到。根据我的公共集群设置进行验证时，我没有看到任何问题。有人可以解释一下为什么我无法访问似乎运行良好的 pod 吗？

此外，即使在虚拟网络上的虚拟机上，我似乎也无法访问入口的外部 IP。但我可以运行 kubectl 命令并访问 kubernetes 仪表板。
