【问题描述】：

我正在完成“以艰难的方式学习 kubernetes”并处于“引导 etcd 集群”步骤：https://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/07-bootstrapping-etcd.md

我遇到了一个导致超时的命令：

somersbmatthews@controller-0:~$ {   sudo systemctl daemon-reload;   sudo systemctl enable etcd;   sudo systemctl start etcd; }
Job for etcd.service failed because a timeout was exceeded.
See "systemctl status etcd.service" and "journalctl -xe" for details.

这里我遵循上述建议：

这是 CLI 要求我检查的第一件事：

somersbmatthews@controller-0:~$ systemctl status etcd.service

但我仍然收到上述超时错误。

感谢任何帮助，谢谢:)

【解决方案1】：

您似乎需要使用 update 子命令更改 VPC 网络的源范围；试试：

$ gcloud compute firewall-rules update kubernetes-the-hard-way-allow-internal --source-ranges 10.240.0.0/24,10.200.0.0/16

我试过这个，但仍然遇到同样的问题。感谢您的帮助:)
