Test docker image as part of the build (docker in docker)

Drone Support

I have a build which produces a roofs file system which I need to boot for additional configuration.
To boot the rootfs I use docker and then SSH to it for configuration.
To access docker inside drone docker I use the following configuration:

privileged: true
network_mode: host
volumes:
  - /usr/bin/docker:/usr/bin/docker
  - /var/run/docker.sock:/var/run/docker.sock

Then with docker I import rootfs, run /sbin/init, wait for SSH, run few SSH commands, stop container.

It works great, but I would like to know if it is possible to get drone help for that?

Ideally:

  1. service which can use rootfs from previous steps
  2. same docker network as other steps
  3. Automatic cleanup of the service docker container and image

Thank you
