The gitlab service exposes only an Unix socket at
<literal>/run/gitlab/gitlab-workhorse.socket</literal>. You need to
configure a webserver to proxy HTTP requests to the socket.

For instance, the following configuration could be used to use nginx as
frontend proxy:
<programlisting>
<link linkend="opt-services.nginx.enable">services.nginx</link> = {
<link linkend="opt-services.nginx.enable">enable</link> = true;
<link linkend="opt-services.nginx.recommendedGzipSettings">recommendedGzipSettings</link> = true;

Gitlab depends on both PostgreSQL and Redis and will automatically enable
both services. In the case of PostgreSQL, a database and a role will be
created.

The default state dir is <literal>/var/gitlab/state</literal>. This is where
all data like the repositories and uploads will be stored.

A basic configuration with some custom settings could look like this:
<programlisting>

If you're setting up a new Gitlab instance, generate new
secrets. You for instance use <literal>tr -dc A-Za-z0-9 &lt;
/dev/urandom | head -c 128 &gt; /var/keys/gitlab/db</literal> to
generate a new db secret. Make sure the files can be read by, and
only by, the user specified by <link
linkend="opt-services.gitlab.user">services.gitlab.user</link>. Gitlab
encrypts sensitive data stored in the database. If you're restoring
an existing Gitlab instance, you must specify the secrets secret
from <literal>config/secrets.yml</literal> located in your Gitlab
state folder.

When <literal>icoming_mail.enabled</literal> is set to <literal>true</literal>
in <link linkend="opt-services.gitlab.extraConfig">extraConfig</link> an additional
service called <literal>gitlab-mailroom</literal> is enabled for fetching incoming mail.

Refer to <xref linkend="ch-options" /> for all available configuration

You can run Gitlab's rake tasks with <literal>gitlab-rake</literal> which
will be available on the system when gitlab is enabled. You will have to run
the command as the user that you configured to run gitlab with.

<para>
For example, to backup a Gitlab instance:
<screen>
<prompt>$ </prompt>sudo -u git -H gitlab-rake gitlab:backup:create
</screen>
A list of all availabe rake tasks can be obtained by running:
<screen>
<prompt>$ </prompt>sudo -u git -H gitlab-rake -T
</screen>
