Is it possible to start real docker daemon in docker?

I need to run docker inside of another docker for some reason. Mapping docker.socket is not an option, I need real docker daemon to start within docker.

Does anybody know if this is possible?

Solution

  • That is what jpetazzo/dind experimented with a few years ago.

    Today (2018), If you want to run Docker-in-Docker today, all you need to do is:

    docker run --privileged -d docker:dind

    He adds:

    ... And that's it; you get Docker running in Docker, thanks to the official Docker image, in its "Docker-in-Docker" flavor.
    You can then connect to this Docker instance by starting another Docker container linking to the first one (which is a pretty amazing thing to do).

    See its official documentation.
