What is GitLab?

GitLab offers git repository management, code reviews, issue tracking, activity feeds, wikis. It has LDAP/AD integration, handles 25,000 users on a single server but can also run on a highly available active/active cluster. A subscription gives you access to our support team and to GitLab Enterprise Edition that contains extra features aimed at larger organizations.


How to use this image.

I recommend creating a data volume container first, this will simplify migrations and backups:

docker run --name gitlab_data genezys/gitlab:7.5.1 /bin/true

This empty container will exist to persist as volumes the 3 directories used by GitLab, so remember not to delete it:

- `/var/opt/gitlab` for application data

- `/var/log/gitlab` for logs

- `/etc/gitlab` for configuration

Then run GitLab:

docker run --detach --name gitlab --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data genezys/gitlab:7.5.1

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`.

How to configure GitLab.

This container uses the official Omnibus GitLab distribution, so all configuration is done in the unique configuration file `/etc/gitlab/gitlab.rb`.

To access GitLab configuration, you can start a new container using the shared data volume container:

docker run -ti --rm --volumes-from gitlab_data ubuntu vi /etc/gitlab/gitlab.rb

**Note** that GitLab will reconfigure itself **at each container start.** You will need to restart the container to reconfigure your GitLab.

You can find all available options in [GitLab documentation](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md#configuration).
