Question

我尝试从一台服务器连接到另一台服务器。事实上，我试图从docker容器中连接到我的主机操作系统（CoreOS）。我已经设置了一个RSA密钥，当使用标准命令行连接到远程主机时，它就像一个魅力。它按预期工作。

当我试图运行/* Extra small devices (phones, less than 768px) */ /* No media query since this is the default in Bootstrap */ /* Small devices (tablets, 768px and up) */ @media (min-width: @screen-sm-min) { ... } /* Medium devices (desktops, 992px and up) */ @media (min-width: @screen-md-min) { ... } /* Large devices (large desktops, 1200px and up) */ @media (min-width: @screen-lg-min) { ... }时，我遇到了此错误

10.45.1.107 | FAILED =＆gt; SSH在连接期间遇到未知错误。我们建议您使用-vvvv重新运行该命令，这将启用SSH调试输出以帮助诊断问题

详细选项如下所示：

ansible customercare -m ping --user=core --connection=ssh --private-key=/home/jenkins/.ssh/id_rsa

有关正在发生的事情的任何线索？

[UPDATE] 这是来自成功SSH登录的日志：

Answer 1

我在coreOS主机上的docker容器中运行ansible时遇到了同样的问题。在这个帖子的帮助下，我可以跟进-O ControlPath选项。关闭加速对我来说没什么帮助。将ssh_args=行更改为空字符串对我来说很有用。

Answer 2

我发现here使用覆盖存储驱动程序时，在docker中ssh管道传输失败的原因之一是一个错误。然后快速修复以更改控制路径的目录。在/etc/ansible/ansible.cfg添加

[ssh_connection] control_path_dir=/dev/shm/ansible_control_path

Answer 3

关闭加速选项就可以了。所以在/etc/ansible/ansible.cfg我添加了accelerate: false并注释掉了其他加速选项。

似乎工作。非常感谢Thomasleveil
