GitLab Documentation

GitLab Integration

GitLab integrates with multiple third-party services to allow external issue trackers and external authentication.

See the documentation below for details on how to configure these services.

GitLab Enterprise Edition contains advanced Jenkins support.

Project services

Integration with services such as Campfire, Flowdock, Gemnasium, HipChat, Pivotal Tracker, and Slack are available in the form of a Project Service.

SSL certificate errors

When trying to integrate GitLab with services that are using self-signed certificates, it is very likely that SSL certificate errors will occur on different parts of the application, most likely Sidekiq. There are 2 approaches you can take to solve this:

  1. Add the root certificate to the trusted chain of the OS.
  2. If using Omnibus, you can add the certificate to GitLab's trusted certificates.

OS main trusted chain

This resource has all the information you need to add a certificate to the main trusted chain.

This answer at Super User also has relevant information.

Omnibus Trusted Chain

Install the self signed certificate or custom certificate authorities in to GitLab Omnibus.

It is enough to concatenate the certificate to the main trusted certificate however it may be overwritten during upgrades:

cat jira.pem >> /opt/gitlab/embedded/ssl/certs/cacert.pem

After that restart GitLab with:

sudo gitlab-ctl restart
