Error while running a test locally with docker:dind

Summary

I have a pipeline stage that uses the docker:dind image. I am trying to run that locally but docker fails to start in the docker container, causing the local build to fail.

Steps to reproduce

I ran gitlab-ci-multi-runner exec docker test

Actual behavior

$ gitlab-ci-multi-runner exec docker test
Running with gitlab-ci-multi-runner 1.10.2 (d171b73)
