Docker image

hi,

i got this error:

Using Docker executor with image gitlab.com/user/project:latest
Pulling docker image mysql:latest …
Starting service mysql:latest …
Waiting for services to be up and running…
Pulling docker image gitlab.com/user/project:latest
ERROR: Preparation failed: invalid character ‘<’ looking for beginning of value

I used boot2docker on window 7 to push the image.

Dockerfile:
