<title>Sourcehut</title>
<para>
<link xlink:href="https://sr.ht.com/">Sourcehut</link> is an open-source,
self-hostable software development platform. The server setup can be automated using
<link linkend="opt-services.sourcehut.enable">services.sourcehut</link>.

<title>Basic usage</title>
<para>
Sourcehut is a Python and Go based set of applications.
This NixOS module also provides basic configuration integrating Sourcehut into locally running
<literal>services.nginx</literal>,
<literal>services.redis.servers.sourcehut</literal>,
<literal>services.postfix</literal>
and
<literal>services.postgresql</literal> services.
</para>
<para>
A very basic configuration may look like this:
<programlisting>
{ pkgs, ... }:
let
fqdn =
let
join = hostName: domain: hostName + optionalString (domain != null) ".${domain}";
in join config.networking.hostName config.networking.domain;
in {
networking = {
hostName = "srht";
domain = "tld";
firewall.allowedTCPPorts = [ 22 80 443 ];
};
services.sourcehut = {
enable = true;
git.enable = true;
man.enable = true;
meta.enable = true;
nginx.enable = true;
postfix.enable = true;
postgresql.enable = true;
redis.enable = true;
settings = {
"sr.ht" = {
environment = "production";
global-domain = fqdn;
origin = "https://${fqdn}";
# Produce keys with srht-keygen from sourcehut.coresrht.
network-key = "/run/keys/path/to/network-key";
service-key = "/run/keys/path/to/service-key";
};
webhooks.private-key= "/run/keys/path/to/webhook-key";
};
};
security.acme.certs."${fqdn}".extraDomainNames = [
"meta.${fqdn}"
"man.${fqdn}"
"git.${fqdn}"
];
services.nginx = {
enable = true;
# only recommendedProxySettings are strictly required, but the rest make sense as well.
recommendedTlsSettings = true;
recommendedOptimisation = true;
recommendedGzipSettings = true;
recommendedProxySettings = true;
# Settings to setup what certificates are used for which endpoint.
virtualHosts = {
"${fqdn}".enableACME = true;
"meta.${fqdn}".useACMEHost = fqdn:
"man.${fqdn}".useACMEHost = fqdn:
"git.${fqdn}".useACMEHost = fqdn:
};
};
}
</programlisting>
</para>
<para>
The <literal>hostName</literal> option is used internally to configure the nginx
reverse-proxy. The <literal>settings</literal> attribute set is
used by the configuration generator and the result is placed in <literal>/etc/sr.ht/config.ini</literal>.
</para>
</section>
<section xml:id="module-services-sourcehut-configuration">
<title>Configuration</title>
<para>
All configuration parameters are also stored in
<literal>/etc/sr.ht/config.ini</literal> which is generated by
the module and linked from the store to ensure that all values from <literal>config.ini</literal>
can be modified by the module.
</para>
</section>
<section xml:id="module-services-sourcehut-httpd">
<title>Using an alternative webserver as reverse-proxy (e.g. <literal>httpd</literal>)</title>
<para>
By default, <literal>nginx</literal> is used as reverse-proxy for <literal>sourcehut</literal>.
However, it's possible to use e.g. <literal>httpd</literal> by explicitly disabling
<literal>nginx</literal> using <xref linkend="opt-services.nginx.enable" /> and fixing the
<literal>settings</literal>.
</para>
