How do I start using Gitlab-CI in Gitlab Omnibus edition?

Question

I have installed Gitlab Omnibus gitlab-7.4.3_omnibus.5.1.0.ci-1.el6.x86_64.rpm on CentOS 6.6. I have a few projects created and working fine but I would like to try using the continuous integration features. I don't know where to start and documentation/tutorials are thin on the ground. I have found the following files that do not appear in an older Gitlab omnibus install I have:

/usr/bin/gitlab-ci-rake
/usr/bin/gitlab-ci-rails

I presume I need to do something with these? But do I need a configuration file first? In my projects (Settings > Services > Gitlab CI) I can see there are options for Active, Token and Project Url but I do not know what to put in these fields. Any help to get me started on CI would be appreciated. Cheers,jonny

We recently installed the omnibus GitLab 7.6.2 release which has GitLab CI 5.3 built in. I had the same question. Here's how we got it working.

We're using a single secured server over https; single ip for both gitlab and gitalb-ci hosts. We have dns entries for both host names to a single ip. (Done with an alias for the ci server I think). We have two ssl certificates one for each hostname.

We have the following lines at the top of the /etc/gitlab/gitlab.rb script (found by searching the gitlab site for rb file setup details):

external_url 'https://gitlab.example.edu'
nginx['redirect_http_to_https'] = true

ci_external_url 'https://gitlab-ci.example.edu'
ci_nginx['redirect_http_to_https'] = true

For http, leave out the nginx statements.

If gitlab-ci url displays the gitlab site contents then the ci_nginx statement needs to be corrected.
