  <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>
<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;
  <link linkend="opt-services.nginx.recommendedOptimisation">recommendedOptimisation</link> = true;
  <link linkend="opt-services.nginx.recommendedProxySettings">recommendedProxySettings</link> = true;
  <link linkend="opt-services.nginx.recommendedTlsSettings">recommendedTlsSettings</link> = true;
  <link linkend="opt-services.nginx.virtualHosts">virtualHosts</link>."git.example.com" = {
    <link linkend="opt-services.nginx.virtualHosts._name_.enableACME">enableACME</link> = true;

    <link linkend="opt-services.nginx.virtualHosts._name_.locations._name_.proxyPass">locations."/".proxyPass</link> = "http://unix:/run/gitlab/gitlab-workhorse.socket";

  <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 = {
  <link linkend="opt-services.gitlab.enable">enable</link> = true;
  <link linkend="opt-services.gitlab.databasePasswordFile">databasePasswordFile</link> = "/var/keys/gitlab/db_password";
  <link linkend="opt-services.gitlab.initialRootPasswordFile">initialRootPasswordFile</link> = "/var/keys/gitlab/root_password";

  <link linkend="opt-services.gitlab.host">host</link> = "git.example.com";
  <link linkend="opt-services.gitlab.port">port</link> = 443;
  <link linkend="opt-services.gitlab.user">user</link> = "git";
  <link linkend="opt-services.gitlab.group">group</link> = "git";

    <link linkend="opt-services.gitlab.smtp.enable">enable</link> = true;
    <link linkend="opt-services.gitlab.smtp.address">address</link> = "localhost";
    <link linkend="opt-services.gitlab.smtp.port">port</link> = 25;
  };
  secrets = {
    <link linkend="opt-services.gitlab.secrets.dbFile">dbFile</link> = "/var/keys/gitlab/db";
    <link linkend="opt-services.gitlab.secrets.secretFile">secretFile</link> = "/var/keys/gitlab/secret";
    <link linkend="opt-services.gitlab.secrets.otpFile">otpFile</link> = "/var/keys/gitlab/otp";
    <link linkend="opt-services.gitlab.secrets.jwsFile">jwsFile</link> = "/var/keys/gitlab/jws";

    gitlab = {
      email_from = "gitlab-no-reply@example.com";

      default_projects_features = { builds = false; };
    };
  };
};
</programlisting>
  </para>

  <para>
   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.
  </para>

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

  <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:
<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>
