How to use this image

+Build your own based on the Omnibus packages with the following command (it assumes you're in the GitLab repo root directory):

+We assume using a data volume container, this will simplify migrations and backups.
+This empty container will exist to persist as volumes the 3 directories used by GitLab, so remember not to delete it.
+
+The directories on data container are:
- `/var/opt/gitlab` for application data
- `/var/log/gitlab` for logs
- `/etc/gitlab` for configuration
-Then run GitLab:
+Create the data container with:

+```bash
+sudo docker run --name gitlab_data gitlab_image /bin/true

+After creating this run GitLab:
+
+```bash
+sudo docker run --detach --name gitlab_app --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data gitlab_image
+```
- docker run --detach --name gitlab --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data genezys/gitlab:7.5.1
+It might take a while before the docker container is responding to queries.
-You can then go to `http://localhost:8080/` (or most likely `http://192.168.59.103:8080/` if you use boot2docker). Next time, you can just use `docker start gitlab` and `docker stop gitlab`.
