commit: https://git.buildroot.net/buildroot/commit/?id=8d060da5301ee8e9307af0ce55e4fa509eccc8fb
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This is useful when bind-mounting the docker client binary into
containers for a docker-in-docker setup.
The Docker CLI communicates with the daemon over a socket. It is
sometimes useful to bind-mount the Docker CLI and socket into containers at
run-time, so that scripts within the containers can call the Docker API
in the host using a client compatible with the host daemon.
