如何修复 DigitalOcean Kube.netes 负载均衡器抛出错误 - SyncLoadBalancerFailed

Question

我在使用 kube.netes 集群和使用 Digital Ocean 设置负载均衡器时遇到问题。 配置以前工作过，但我不确定是否有过时的版本或需要一些其他更改才能使其工作。 有没有办法确保 SyncLoadBalancer 成功？ 等了一个多小时，负载均衡器在DigitalOcean dashboard中早就显示在线了。

Answer 1

以下是可能有助于解决您的问题的故障排除步骤：

1. 如果您在 yaml 文件中指定 2 个端口，负载均衡器将占用这 2 个端口之间的整个范围，从而阻塞并使它们无法重新用于其他服务
2. 如果您已将端口 ex:8086 用于转发规则，则不能将其重新用于其他服务
3. 如果您在负载均衡器上启用了健康检查，请检查这些健康检查是否全部通过。
4. 验证负载平衡器是否可以从公共 inte.net 访问。
5. 最后重启集群，再次尝试部署。
