dns-controller Kubernetes 部署尚未更新 Kubernetes 集群的 - AWS

Question

我正在尝试在 aws 上建立一个 kubernetes 集群，但在验证时它一直失败。使用以下命令更新集群kops update cluster cluster.foo.com --yes并运行此命令kops validate cluster

Using cluster from kubectl context: cluster.foo.com

Validating cluster cluster.api.com

The dns-controller Kubernetes deployment has not updated the Kubernetes cluster's API DNS entry to the correct IP address.  The API DNS IP address is the placeholder address that kops creates: 203.0.113.123.  Please wait about 5-10 minutes for a master to start, dns-controller to launch, and DNS to propagate.  The protokube container and dns-controller deployment logs may contain more diagnostic information.  Etcd and the API DNS entries must be updated for a kops Kubernetes cluster to start.

Validation Failed

请帮助查找根本原因。

1. 我尝试多次删除和重新创建，但这对我没有帮助。
2. 还尝试将主公共和私有 IP 手动放置到路由 53，但它破坏了一切。

Answer 1

根据我的经验，如果您的 kops 和 kubectl 以及 kubernetes 平面版本的版本不同，那么 Kops 永远不会更新 Route53 输入项，在我的情况下，您必须需要拥有相同的版本

[root@ip-20-0-0-66 kuberneteswithkops]# kops version
Version 1.15.0 (git-9992b4055)
[root@ip-20-0-0-66 kuberneteswithkops]# kubectl version
