Nextcloud
Nextcloud is an open-source,
self-hostable cloud platform. The server setup can be automated using
services.nextcloud. A
desktop client is packaged at pkgs.nextcloud-client.
Basic usage
Nextcloud is a PHP-based application which requires an HTTP server
(services.nextcloud
optionally supports
services.nginx)
and a database (it's recommended to use
services.postgresql).
A very basic configuration may look like this:
{ pkgs, ... }:
{
services.nextcloud = {
enable = true;
hostName = "nextcloud.tld";
nginx.enable = true;
config = {
dbtype = "pgsql";
dbuser = "nextcloud";
dbhost = "/run/postgresql"; # nextcloud will add /.s.PGSQL.5432 by itself
dbname = "nextcloud";
adminpassFile = "/path/to/admin-pass-file";
adminuser = "root";
};
};
services.postgresql = {
enable = true;
ensureDatabases = [ "nextcloud" ];
ensureUsers = [
{ name = "nextcloud";
ensurePermissions."DATABASE nextcloud" = "ALL PRIVILEGES";
}
];
};
# ensure that postgres is running *before* running the setup
systemd.services."nextcloud-setup" = {
requires = ["postgresql.service"];
after = ["postgresql.service"];
};
networking.firewall.allowedTCPPorts = [ 80 443 ];
}
The options hostName and nginx.enable
are used internally to configure an HTTP server using
PHP-FPM
and nginx. The config 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
$_SERVER['HTTP_HOST'])
it's needed to add them to
services.nextcloud.config.extraTrustedDomains.
Auto updates for Nextcloud apps can be enabled using
services.nextcloud.autoUpdateApps.
Pitfalls
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 nextcloud user (by default
/var/lib/nextcloud/config/config.php) and is also used to
track several states of the application (e.g. whether installed or not).
All configuration parameters are also stored in
/var/lib/nextcloud/config/override.config.php which is generated by
the module and linked from the store to ensure that all values from config.php
can be modified by the module.
However config.php manages the application's state and shouldn't be touched
manually because of that.
Don't delete config.php! This file
tracks the application's state and a deletion can cause unwanted
side-effects!Don't rerun nextcloud-occ
maintenance:install! This command tries to install the application
and can cause unwanted side-effects!
