【问题描述】:
您好,提前感谢您的帮助!
我正在尝试使用 Kubespray(ansible playbook)部署 Kubernetes 集群。我正在尝试在 17 KVM 主机上部署集群(所有节点都运行 centos 7 ,并且托管在裸机服务器上)
但是,当我尝试在任务 [download : file_download | Download item] 处运行剧本时
我收到以下错误(因此停止安装):
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: SSLError: ('The read operation timed out',)
fatal: [node1]: FAILED! => {"attempts": 4, "changed": false, "msg": "failed to create temporary content file: ('The read operation timed out',)"}
这个错误对于大多数节点来说都是一样的,但是,有些节点愿意下载。
这是详细模式下的错误:
The full traceback is:
Traceback (most recent call last):

},

}
我尝试连接到节点并尝试下载一个项目(我尝试下载 Kubspray zip)并且它工作正常,所有节点都连接到互联网并且可以安装包。
从详细的输出中,我有点明白错误来自python,但我真的不知道如何解决它......
如果我可以再给你一条信息,请告诉我,提前谢谢!
【问题讨论】:
-
如果“所有节点都连接到 Internet 并且可以安装包”那么我猜你的登录 shell 正在设置代理变量,而 ansible playbook 没有设置
-
这似乎不是一个编程问题。您可以通过Server Fault 获得帮助。
