Updating

Instructions for updating your Omnibus installation and upgrading from a manual installation are in the update doc.

Uninstalling omnibus-gitlab

To remove all users and groups created by omnibus-gitlab, before removing the gitlab package (with dpkg or yum) run sudo gitlab-ctl remove-accounts. Note All gitlab processes need to be stopped before running the command.

To remove all omnibus-gitlab data use sudo gitlab-ctl cleanse.

To uninstall omnibus-gitlab, preserving your data (repositories, database, configuration), run the following commands.

# Stop gitlab and remove its supervision process
sudo systemctl stop    gitlab-runsvdir
sudo systemctl disable gitlab-runsvdir
sudo rm /usr/lib/systemd/system/gitlab-runsvdir.service
sudo systemctl daemon-reload
sudo gitlab-ctl uninstall

# (Replace with gitlab-ce if you have GitLab FOSS installed)

# Debian/Ubuntu
sudo apt remove gitlab-ee

# Redhat/Centos
sudo yum remove gitlab-ee

Directory structure

Omnibus-gitlab uses four different directories.

• /opt/gitlab holds application code for GitLab and its dependencies.
• /var/opt/gitlab holds application data and configuration files that gitlab-ctl reconfigure writes to.
• /etc/gitlab holds configuration files for omnibus-gitlab. These are the only files that you should ever have to edit manually.
• /var/log/gitlab contains 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.

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.
