ubuntu - 创建 API 客户端，等待控制平面准备就绪

Question

在 ubuntu 16.04 上运行 kubeadm init 时出现以下错误：

系统只是挂了很长时间。

[certificates] Generated API server kubelet client certificate and key.
[certificates] Generated service account token signing key and public key.
[certificates] Generated front-proxy CA certificate and key.
[certificates] Generated front-proxy client certificate and key.
[certificates] Valid certificates and keys now exist in "/etc/kubernetes/pki"
[kubeconfig] Wrote KubeConfig file to disk: "/etc/kubernetes/admin.conf"
[kubeconfig] Wrote KubeConfig file to disk: "/etc/kubernetes/kubelet.conf"
[kubeconfig] Wrote KubeConfig file to disk: "/etc/kubernetes/controller-manager.conf"
[kubeconfig] Wrote KubeConfig file to disk: "/etc/kubernetes/scheduler.conf"
[apiclient] Created API client, waiting for the control plane to become ready

有人遇到这个错误并解决了吗？

我试图：

1. 重启 kubectl 服务
2. kubeadm 重置

但没有任何效果...

Answer 1

遇到这个问题的时候，一直是kubelet的问题。但是kubelet失败或启动组件容器失败的真正原因（controller-manager/kube-apiserver...）是不同的。所以我建议你可以通过使用命令获取 kubelet 的反向日志来添加更多信息：

journalctl -r -u kubelet.service

您可以自己查看日志和调试，也可以在这里粘贴，以便我们了解您的情况。

希望这会有所帮助。
