Possibly due to gitlab#423? When running a Docker-in-Docker CI file, it fails due to not being able to connect to the Docker daemon: ```bash Running with gitlab-runner 10.5.0 (80b03db9) on gitlab-gitlab-runner-7d7c9dcbbc-5nc7v 22b9e572 Using Kubernetes namespace: default Using Kubernetes executor with image docker:latest ...
