<title>Gitlab</title>

<para>Gitlab is a feature-rich git hosting service.</para>

<section><title>Prerequisites</title>

<para>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.</para>

<para>For instance, the following configuration could be used to use nginx as
    frontend proxy:

<programlisting>
    services.nginx = {
      enable = true;
      recommendedGzipSettings = true;
      recommendedOptimisation = true;
      recommendedProxySettings = true;
      recommendedTlsSettings = true;
      virtualHosts."git.example.com" = {
        enableACME = true;
        forceSSL = true;
        locations."/".proxyPass = "http://unix:/run/gitlab/gitlab-workhorse.socket";
      };
    };
'';
</programlisting>
</para>

</section>

<section><title>Configuring</title>

<para>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.
</para>

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

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

<programlisting>
services.gitlab = {
  enable = true;
  databasePassword = "eXaMpl3";
  initialRootPassword = "UseNixOS!";
  https = true;
  host = "git.example.com";
  port = 443;
  user = "git";
  group = "git";
  smtp = {
    enable = true;
    address = "localhost";
    port = 25;
  };
  extraConfig = {
    gitlab = {
      email_from = "gitlab-no-reply@example.com";
      email_display_name = "Example GitLab";
      email_reply_to = "gitlab-no-reply@example.com";
      default_projects_features = { builds = false; };
    };
  };
};
</programlisting>
</para>

<para>Refer to <xref linkend="ch-options" /> for all available configuration
options for the <literal>services.gitlab</literal> module.</para>

</section>

<section><title>Maintenance</title>

<para>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>

<para>For example, to backup a Gitlab instance:

<programlisting>
$ sudo -u git -H gitlab-rake gitlab:backup:create
</programlisting>

A list of all availabe rake tasks can be obtained by running:

<programlisting>
$ sudo -u git -H gitlab-rake -T
</programlisting>
</para>
