Ansible Role gitlab_ce

This role installs and configures GitLab CE, including regular backups.

After installation, the password for the first user „root“ can be found in /etc/gitlab/initial_root_password.
One of the first steps after that would be to deactivate the registration form: In the left sidebar, select Admin > Settings > General, and expand „Sign-up restrictions“. Clear the „Sign-up enabled“ checkbox, then select „Save changes“ (you can’t disable signups without using the UI).

Mandatory Requirements

Enable the official GitLab CE Repository. This can be done using the linuxfabrik.lfops.repo_gitlab_ce role.

If you use the gitlab_ce Playbook, this is automatically done for you.

Tags

Tag	What it does	Reload / Restart
`gitlab_ce`	* `install tar gitlab-ce` * `mkdir -p /backup/gitlab` * Deploy `/etc/systemd/system/gitlab-dump.service` * Deploy `/etc/systemd/system/gitlab-dump.timer` * `systemctl enable gitlab-dump.timer --now` * Deploy `/etc/gitlab/gitlab.rb` * `gitlab-ctl reconfigure` * `gitlab-ctl restart`	`gitlab-ctl restart`
`gitlab_ce:configure`	Same as above, but without install.	`gitlab-ctl restart`

Mandatory Role Variables

Variable	Description
`gitlab_ce__rb_external_url`	The URL of your GitLab instance. Currently, only `http://` is supported by this role. If running behind a reverse proxy or on a trusted network, this is good enough.

Example:

# mandatory
gitlab_ce__rb_external_url: 'http://git.example.com'
