Jia*_*Cao 10 amazon-web-services kubernetes
我使用kubeadm在AWS上启动集群.我可以使用kubectl在AWS上成功创建负载均衡器,但负载均衡器未在任何EC2实例中注册.这导致无法从公共访问服务的问题.
从观察中,当创建ELB时,它无法在所有子网下找到任何健康的实例.我很确定我正确标记了所有实例.
更新:我正在从k8s-controller-manager读取日志,它显示我的节点没有设置ProviderID.根据Github的评论,ELB将忽略无法从提供商确定实例ID的节点.这会导致这个问题吗？我该如何设置providerID？

我该如何解决这个问题？
谢谢!

就我而言 - 问题是缺少选项--cloud-provider=aws
在我将以下内容放入 /etc/default/kubelet （在我的例子中通过 terraform ）并重新部署我的节点后，一切正常
/etc/默认/kubelet
KUBELET_EXTRA_ARGS='--cloud-provider=aws'
