Directory structure
Omnibus-gitlab uses four different directories.
/opt/gitlabholds application code for GitLab and its dependencies./var/opt/gitlabholds application data and configuration files thatgitlab-ctl reconfigurewrites to./etc/gitlabholds configuration files for omnibus-gitlab. These are the only files that you should ever have to edit manually./var/log/gitlabcontains all log data generated by components of omnibus-gitlab.
Omnibus-gitlab and SELinux
Although omnibus-gitlab runs on systems that have SELinux enabled, it does not use SELinux confinement features:
- omnibus-gitlab creates unconfined system users;
- omnibus-gitlab services run in an unconfined context.
The correct operation of Git access via SSH depends on the labeling of
/var/opt/gitlab/.ssh. If needed you can restore this labeling by running
sudo gitlab-ctl reconfigure.
Depending on your platform, gitlab-ctl reconfigure will install SELinux
modules required to make GitLab work. These modules are listed in
files/gitlab-selinux/README.md.
NSA, if you're reading this, we'd really appreciate it if you could contribute back a SELinux profile for omnibus-gitlab :) Of course, if anyone else is reading this, you're welcome to contribute the SELinux profile too.
Logs
This section has been moved to separate document doc/settings/logs.md.

Building your own package
See the separate build documentation.
Running a custom GitLab version
It is not recommended to make changes to any of the files in /opt/gitlab
after installing omnibus-gitlab: they will either conflict with or be
overwritten by future updates. If you want to run a custom version of GitLab
you can build your own package or use another installation
method.
