gitlab-runner exec docker does not find repo

I am having trouble running the gitlab-runner exec command using the docker executor. The git repo cannot be found.

I have the following setup:

• Windows 10, running Docker for Windows
• Docker + gitlab-ci-multi-runner installed in a container with the Docker file below

FROM phusion/baseimage:0.9.19

RUN apt-get update \
    && sh -c "curl -sSL https://get.docker.com/ | sh" \
    && sh -c "curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.deb.sh | bash" \
    && apt-get install -y gitlab-ci-multi-runner \
    && apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

CMD ["/sbin/my_init"]

I run the image (built with -t docker-gitlab-runner:snapshot) above with:

$ docker run --rm -it --name gt -v C:/Users/jnaous:/home/jnaous -v /var/run/docker.sock:/var/run/docker.sock -v C:/Users/jnaous/gitlab/config:/etc/gitlab-runner docker-gitlab-runner:snapshot /sbin/my_init -- bash -l -i

My git repo is now mounted in the container at /home/jnaous/candidguru/candidly. Now the .gitlab-ci.yml file I'm running also starts up docker:dind as a service.

For some reason, the repo is not found, even though I think it is actually getting mounted according to the log: Using host-based /home/jnaous/candidguru/candidly for /home/jnaous/candidguru/candidly:ro

Mentioned in issue #1729

Status changed to closed

Figured out how to do this directly from windows, without the extra nesting, but having issues. See #1775
