是否有可能从容器到主机执行Docker调用? [英] Is it possible to perform Docker-call from a container into the host?
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.
