我正在尝试为Spring Boot 项目在K8S集群中启动MySQL服务器。K8S运行在Docker桌面上。为了在本地访问DB，我已经设置了一个负载均衡器服务。当DB服务器ups我的负载均衡器服务外部IP卡在挂起状态。我已经做了一个类似的事情点-net项目早些时候在windows OS K8S上docker没有问题，我得到了外部IP作为localhost的sql server安装.我已经附上了相关的代码.帮助将不胜感激.谢谢.

在公共云提供商环境中，会调配外部负载均衡器，并将其公共IP地址分配给您的服务，并且自动执行将流量从负载均衡器定向到群集节点所需的网络配置。
问题是您的本地kubernetes集群没有为LoadBalancer类型的服务分配IP地址的机制。如果您确实想要LoadBalancer IP，可以使用MetalLB的L2模式安装。您需要设置合适的IPAddressPool配置。MetalLB的kind安装步骤与docker桌面相同。
如果你在linux机器上，你应该能够直接从主机ping IP，因为主机网络和Docker网络是连通的。

注意

如果kubectl port-forward不是一个选项，那么就进行上面的安装。否则，端口转发就足以连接到主机上运行的数据库客户端。
