Nextcloud is a PHP-based application which requires an HTTP server
|
|
(<literal><link linkend="opt-services.nextcloud.enable">services.nextcloud</link></literal>
|
|
optionally supports
|
|
<literal><link linkend="opt-services.nginx.enable">services.nginx</link></literal>)
|
|
and a database (it's recommended to use
|
|
<literal><link linkend="opt-services.postgresql.enable">services.postgresql</link></literal>).

A very basic configuration may look like this:

<programlisting>{ pkgs, ... }:

services.nextcloud = {

The options <literal>hostName</literal> and <literal>nginx.enable</literal>
|
|
are used internally to configure an HTTP server using
|
|
<literal><link xlink:href="https://php-fpm.org/">PHP-FPM</link></literal>
|
|
and <literal>nginx</literal>. The <literal>config</literal> attribute set is
|
|
used by the imperative installer and all values are written to an additional file
|
|
to ensure that changes can be applied by changing the module's options.

In case the application serves multiple domains (those are checked with
|
|
<literal><link xlink:href="http://php.net/manual/en/reserved.variables.server.php">$_SERVER['HTTP_HOST']</link></literal>)
|

it's needed to add them to

Unfortunately Nextcloud appears to be very stateful when it comes to
|
|
managing its own configuration. The config file lives in the home directory
|
|
of the <literal>nextcloud</literal> user (by default
|
|
<literal>/var/lib/nextcloud/config/config.php</literal>) and is also used to
|
|
track several states of the application (e.g. whether installed or not).
|
|
</para>
|
|
|
|
<para>
|
|
All configuration parameters are also stored in
|
|
<literal>/var/lib/nextcloud/config/override.config.php</literal> which is generated by
|
|
the module and linked from the store to ensure that all values from <literal>config.php</literal>
|
|
can be modified by the module.
|
|
However <literal>config.php</literal> manages the application's state and shouldn't be touched
|
|
manually because of that.
