问题描述
我想能够，例如，从容器内重新启动主机容器。
I would like to be able to, e.g., restart host containers from inside a container.
有谁知道是否有任何方法可以做到这一点？ / p>
Does anyone know whether there is any way I could do that?
推荐答案
假设你的问题是是否有可能从容器到主机执行Docker调用？
是的，一定可以！ 与Docker守护程序的通信通过一个套接字。默认情况下，该套接字是 unix：///var/run/docker.sock 。您的管理器容器只需要访问（和许可）到此套接字。
Yeah, sure it is possible!
The communication with the Docker daemon goes through a socket. By default this socket is the unix:///var/run/docker.sock. Your manager-container just need access (and permission) to this socket.
请注意，Docker守护程序的选项（我正在查看ou -H，--host ）允许通过 TCP （或甚至 fd ）。
Note that an option of the Docker daemon (I'm looking at ou -H, --host) allows the communication through TCP (or even a fd).
然后您只需要一个Docker客户端（任何Docker API实现）进行通信。
You then just need a Docker client (any Docker API implementation) to communicate.
