我正在尝试使用本地kubernetes集群中的入口控制器为我的两个Web应用程序设置前端 . 我按照[1]中概述的所有步骤和[2]中的详细说明进行操作 . 但到目前为止运气不好 . 我得到的错误如下：
Warning CreatingLoadBalancerFailed Error creating load balancer (will retry): failed to ensure load balancer for service default/frontend: error creating loadbalancer a58617b3f260011e8ad84fa163e0c90a: error creating loadbalancer {a58617b3f260011e8ad84fa163e0c90a

but got 409 instead
{"NeutronError": {"message": "Quota exceeded for resources: ['loadbalancer'].", "type": "OverQuota", "detail": ""}}
我的服务处于待定状态 .
到目前为止，我不知道在哪里查找以确定问题，并希望得到任何建议 .
清单yaml文件几乎与[2]相同，它只列出https接口 . 但这是为了完整性

看起来kubernetes正在使用OpenStack lbaas来配置入口资源下的负载均衡器服务（请参阅错误日志中的
https://host.xyz.com:9696/v2.0/lbaas/loadbalancers）AFAIK此错误表示已配置的负载 balancer 器数量已达到资源限制 . 我会向您的群集管理员提出此问题 .
您的服务正在尝试在AWS中创建新的Load Balancer，并且超出了您所在区域的配额 . 我认为你有20个，因为这是默认值：https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html#limits_elastic_load_balancer
以下是有关如何申请限额增加的说明：https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html
