<title>Input Methods</title>
<para>
Input methods are an operating system component that allows any
data, such as keyboard strokes or mouse movements, to be received as
input. In this way users can enter characters and symbols not found
on their input devices. Using an input method is obligatory for any
language that has more graphemes than there are keys on the
keyboard.
</para>
<para>
The following input methods are available in NixOS:

from IBus’ preference dialog.
</para>
<section xml:id="module-services-input-methods-troubleshooting">
<title>Troubleshooting</title>
<para>
If IBus works in some applications but not others, a likely
cause of this is that IBus is depending on a different version
of <literal>glib</literal> to what the applications are
depending on. This can be checked by running
<literal>nix-store -q --requisites &lt;path&gt; | grep glib</literal>,
where <literal>&lt;path&gt;</literal> is the path of either IBus
or an application in the Nix store. The <literal>glib</literal>
packages must match exactly. If they do not, uninstalling and
reinstalling the application is a likely fix.

<title>SSL/TLS Certificates with ACME</title>
<para>
NixOS supports automatic domain validation &amp; certificate
retrieval and renewal using the ACME protocol. Any provider can be
used, but by default NixOS uses Let’s Encrypt. The alternative ACME
client
<link xlink:href="https://go-acme.github.io/lego/">lego</link> is
used under the hood.
</para>
<para>
Automatic cert validation and configuration for Apache and Nginx
virtual hosts is included in NixOS, however if you would like to
generate a wildcard cert or you are not using a web server you will
have to configure DNS based validation.
</para>
<section xml:id="module-security-acme-prerequisites">
<title>Prerequisites</title>
<para>
To use the ACME module, you must accept the provider’s terms of
service by setting
<xref linkend="opt-security.acme.acceptTerms" /> to
<literal>true</literal>. The Let’s Encrypt ToS can be found
<link xlink:href="https://letsencrypt.org/repository/">here</link>.
</para>
<para>
You must also set an email address to be used when creating
accounts with Let’s Encrypt. You can set this for all certs with
<xref linkend="opt-security.acme.defaults.email" /> and/or on a
per-cert basis with
<xref linkend="opt-security.acme.certs._name_.email" />. This
address is only used for registration and renewal reminders, and
cannot be used to administer the certificates in any way.
</para>
<para>
Alternatively, you can use a different ACME server by changing the
<xref linkend="opt-security.acme.defaults.server" /> option to a
provider of your choosing, or just change the server for one cert
with <xref linkend="opt-security.acme.certs._name_.server" />.
</para>
<para>
You will need an HTTP server or DNS server for verification. For
HTTP, the server must have a webroot defined that can serve
<filename>.well-known/acme-challenge</filename>. This directory
must be writeable by the user that will run the ACME client. For
DNS, you must set up credentials with your provider/server for use
with lego.

first create self-signed placeholder certificates in place of the
real ACME certs. The placeholder certs are overwritten when the
ACME certs arrive. For <literal>foo.example.com</literal> the
config would look like this:

This is useful if you want to generate a wildcard certificate,

validation. There are a number of supported DNS providers and

You must follow the guide above on configuring DNS-01 validation
first, however instead of setting the options for one certificate

FoundationDB (or <quote>FDB</quote>) is an open source, distributed,
transactional key-value store.
</para>
<section xml:id="module-services-foundationdb-configuring">
<title>Configuring and basic setup</title>
<para>
To enable FoundationDB, add the following to your
<filename>configuration.nix</filename>:
</para>
<programlisting>
services.foundationdb.enable = true;
services.foundationdb.package = pkgs.foundationdb52; # FoundationDB 5.2.x
</programlisting>
<para>
The <option>services.foundationdb.package</option> option is
required, and must always be specified. Due to the fact
FoundationDB network protocols and on-disk storage formats may
change between (major) versions, and upgrades must be explicitly
handled by the user, you must always manually specify this
yourself so that the NixOS module will use the proper version.
Note that minor, bugfix releases are always compatible.
</para>
<para>
After running <command>nixos-rebuild</command>, you can verify
whether FoundationDB is running by executing
<command>fdbcli</command> (which is added to
<option>environment.systemPackages</option>):
</para>
<programlisting>
$ sudo -u foundationdb fdbcli
Using cluster file `/etc/foundationdb/fdb.cluster'.
The database is available.
Welcome to the fdbcli. For help, type `help'.
fdb&gt; status

Redundancy mode - single
Storage engine - memory

Fault Tolerance - 0 machines
Server time - 04/20/18 15:21:14
...
fdb&gt;
</programlisting>
<para>
You can also write programs using the available client libraries.
For example, the following Python program can be run in order to
grab the cluster status, as a quick example. (This example uses
<command>nix-shell</command> shebang support to automatically
supply the necessary Python modules).
</para>
<programlisting>
a@link&gt; cat fdb-status.py
#! /usr/bin/env nix-shell
#! nix-shell -i python -p python pythonPackages.foundationdb52
import fdb
import json
def main():
fdb.api_version(520)
db = fdb.open()
@fdb.transactional
def get_status(tr):
return str(tr['\xff\xff/status/json'])
obj = json.loads(get_status(db))
print('FoundationDB available: %s' % obj['client']['database_status']['available'])
if __name__ == &quot;__main__&quot;:
main()
a@link&gt; chmod +x fdb-status.py
a@link&gt; ./fdb-status.py
FoundationDB available: True
a@link&gt;
</programlisting>
<para>
FoundationDB is run under the <command>foundationdb</command> user
and group by default, but this may be changed in the NixOS
configuration. The systemd unit
<command>foundationdb.service</command> controls the
<command>fdbmonitor</command> process.
</para>
<para>
By default, the NixOS module for FoundationDB creates a single
SSD-storage based database for development and basic usage. This
storage engine is designed for SSDs and will perform poorly on
HDDs; however it can handle far more data than the alternative
<quote>memory</quote> engine and is a better default choice for
most deployments. (Note that you can change the storage backend
on-the-fly for a given FoundationDB cluster using
<command>fdbcli</command>.)
</para>
<para>
Furthermore, only 1 server process and 1 backup agent are started
in the default configuration. See below for more on scaling to
increase this.
</para>
<para>
FoundationDB stores all data for all server processes under
<filename>/var/lib/foundationdb</filename>. You can override this
using <option>services.foundationdb.dataDir</option>, e.g.
</para>
<programlisting>
services.foundationdb.dataDir = &quot;/data/fdb&quot;;
</programlisting>
<para>
Similarly, logs are stored under
<filename>/var/log/foundationdb</filename> by default, and there
is a corresponding <option>services.foundationdb.logDir</option>
as well.
</para>
</section>
<section xml:id="module-services-foundationdb-scaling">
<title>Scaling processes and backup agents</title>
<para>
Scaling the number of server processes is quite easy; simply
specify <option>services.foundationdb.serverProcesses</option> to
be the number of FoundationDB worker processes that should be
started on the machine.
</para>
<para>
FoundationDB worker processes typically require 4GB of RAM
per-process at minimum for good performance, so this option is set
to 1 by default since the maximum amount of RAM is unknown. You’re
advised to abide by this restriction, so pick a number of
processes so that each has 4GB or more.
</para>
<para>
A similar option exists in order to scale backup agent processes,
<option>services.foundationdb.backupProcesses</option>. Backup
agents are not as performance/RAM sensitive, so feel free to
experiment with the number of available backup processes.
</para>
</section>
<section xml:id="module-services-foundationdb-clustering">
<title>Clustering</title>
<para>
FoundationDB on NixOS works similarly to other Linux systems, so
this section will be brief. Please refer to the full FoundationDB
documentation for more on clustering.
</para>
<para>
FoundationDB organizes clusters using a set of
<emphasis>coordinators</emphasis>, which are just
specially-designated worker processes. By default, every
installation of FoundationDB on NixOS will start as its own
individual cluster, with a single coordinator: the first worker
process on <command>localhost</command>.
</para>
<para>
Coordinators are specified globally using the
<command>/etc/foundationdb/fdb.cluster</command> file, which all
servers and client applications will use to find and join
coordinators. Note that this file <emphasis>can not</emphasis> be
managed by NixOS so easily: FoundationDB is designed so that it
will rewrite the file at runtime for all clients and nodes when
cluster coordinators change, with clients transparently handling
this without intervention. It is fundamentally a mutable file, and
you should not try to manage it in any way in NixOS.
</para>
<para>
When dealing with a cluster, there are two main things you want to
do:
</para>
<itemizedlist spacing="compact">
<listitem>
<para>
Add a node to the cluster for storage/compute.
</para>

<para>
A node must already be a member of the cluster in order to
properly be promoted to a coordinator, so you must always add it
first if you wish to promote it.
</para>
<para>
To add a machine to a FoundationDB cluster:
</para>
<itemizedlist spacing="compact">
<listitem>
<para>
Choose one of the servers to start as the initial coordinator.
</para>
</listitem>
<listitem>
<para>
Copy the <command>/etc/foundationdb/fdb.cluster</command> file
from this server to all the other servers. Restart
FoundationDB on all of these other servers, so they join the
cluster.
</para>
</listitem>
<listitem>
<para>
All of these servers are now connected and working together in
the cluster, under the chosen coordinator.
</para>
</listitem>
</itemizedlist>
<para>
At this point, you can add as many nodes as you want by just
repeating the above steps. By default there will still be a single
coordinator: you can use <command>fdbcli</command> to change this
and add new coordinators.
</para>
<para>
As a convenience, FoundationDB can automatically assign
coordinators based on the redundancy mode you wish to achieve for
the cluster. Once all the nodes have been joined, simply set the
replication policy, and then issue the
<command>coordinators auto</command> command
</para>
<para>
For example, assuming we have 3 nodes available, we can enable
double redundancy mode, then auto-select coordinators. For double
redundancy, 3 coordinators is ideal: therefore FoundationDB will
make <emphasis>every</emphasis> node a coordinator automatically:
</para>
<programlisting>
fdbcli&gt; configure double ssd
fdbcli&gt; coordinators auto
</programlisting>
<para>
This will transparently update all the servers within seconds, and
appropriately rewrite the <command>fdb.cluster</command> file, as
well as informing all client processes to do the same.
</para>
</section>
<section xml:id="module-services-foundationdb-connectivity">
<title>Client connectivity</title>
<para>
By default, all clients must use the current
<command>fdb.cluster</command> file to access a given FoundationDB
cluster. This file is located by default in
<command>/etc/foundationdb/fdb.cluster</command> on all machines
with the FoundationDB service enabled, so you may copy the active
one from your cluster to a new node in order to connect, if it is
not part of the cluster.
</para>
</section>
<section xml:id="module-services-foundationdb-authorization">
<title>Client authorization and TLS</title>
<para>
By default, any user who can connect to a FoundationDB process
with the correct cluster configuration can access anything.
FoundationDB uses a pluggable design to transport security, and
out of the box it supports a LibreSSL-based plugin for TLS
support. This plugin not only does in-flight encryption, but also
performs client authorization based on the given endpoint’s
certificate chain. For example, a FoundationDB server may be
configured to only accept client connections over TLS, where the
client TLS certificate is from organization <emphasis>Acme
Co</emphasis> in the <emphasis>Research and Development</emphasis>
unit.
</para>
<para>
Configuring TLS with FoundationDB is done using the
<option>services.foundationdb.tls</option> options in order to
control the peer verification string, as well as the certificate
and its private key.
</para>
<para>
Note that the certificate and its private key must be accessible
to the FoundationDB user account that the server runs under. These
files are also NOT managed by NixOS, as putting them into the
store may reveal private information.
</para>
<para>
After you have a key and certificate file in place, it is not
enough to simply set the NixOS module options – you must also
configure the <command>fdb.cluster</command> file to specify that
a given set of coordinators use TLS. This is as simple as adding
the suffix <command>:tls</command> to your cluster coordinator
configuration, after the port number. For example, assuming you
have a coordinator on localhost with the default configuration,
simply specifying:
</para>
<programlisting>
XXXXXX:XXXXXX@127.0.0.1:4500:tls
</programlisting>
<para>
will configure all clients and server processes to use TLS from
now on.
</para>
</section>
<section xml:id="module-services-foundationdb-disaster-recovery">
<title>Backups and Disaster Recovery</title>
<para>
The usual rules for doing FoundationDB backups apply on NixOS as
written in the FoundationDB manual. However, one important
difference is the security profile for NixOS: by default, the
<command>foundationdb</command> systemd unit uses <emphasis>Linux
namespaces</emphasis> to restrict write access to the system,
except for the log directory, data directory, and the
<command>/etc/foundationdb/</command> directory. This is enforced
by default and cannot be disabled.
</para>
<para>
However, a side effect of this is that the
<command>fdbbackup</command> command doesn’t work properly for
local filesystem backups: FoundationDB uses a server process
alongside the database processes to perform backups and copy the
backups to the filesystem. As a result, this process is put under
the restricted namespaces above: the backup process can only write
to a limited number of paths.
</para>
<para>
In order to allow flexible backup locations on local disks, the
FoundationDB NixOS module supports a
<option>services.foundationdb.extraReadWritePaths</option> option.
This option takes a list of paths, and adds them to the systemd
unit, allowing the processes inside the service to write (and
read) the specified directories.
</para>
<para>
For example, to create backups in
<command>/opt/fdb-backups</command>, first set up the paths in the
module options:
</para>
<programlisting>
services.foundationdb.extraReadWritePaths = [ &quot;/opt/fdb-backups&quot; ];
</programlisting>
<para>
Restart the FoundationDB service, and it will now be able to write
to this directory (even if it does not yet exist.) Note: this path
<emphasis>must</emphasis> exist before restarting the unit.
Otherwise, systemd will not include it in the private FoundationDB
namespace (and it will not add it dynamically at runtime).
</para>
<para>
You can now perform a backup:
</para>
<programlisting>
$ sudo -u foundationdb fdbbackup start -t default -d file:///opt/fdb-backups
$ sudo -u foundationdb fdbbackup status -t default
</programlisting>
</section>

Major PostgreSQL upgrades require a downtime and a few imperative

Emacs installation is to create a dedicated derivation. This can
be done in a dedicated <filename>emacs.nix</filename> file such
as:

<link xlink:href="https://matrix.org/">Matrix</link> is an open
standard for interoperable, decentralised, real-time communication

This chapter will show you how to set up your own, self-hosted
Matrix homeserver using the Synapse reference homeserver, and how to
serve your own copy of the Element web client. See the

<title>Registering Matrix users</title>
<para>
If you want to run a server with public registration by anybody,
you can then enable
<literal>services.matrix-synapse.settings.enable_registration = true;</literal>.
Otherwise, or you can generate a registration secret with
<command>pwgen -s 64 1</command> and set it with
<xref linkend="opt-services.matrix-synapse.settings.registration_shared_secret" />.
To create a new user or admin, run the following after you have
set the secret and have rebuilt NixOS:
</para>
<programlisting>
$ nix-shell -p matrix-synapse
$ register_new_matrix_user -k your-registration-shared-secret http://localhost:8008
New user localpart: your-username
Password:
Confirm password:
Make admin [no]:
Success!
</programlisting>
<para>
In the example, this would create a user with the Matrix
Identifier <literal>@your-username:example.org</literal>.
</para>
<warning>
<para>
When using
<xref linkend="opt-services.matrix-synapse.settings.registration_shared_secret" />,
the secret will end up in the world-readable store. Instead it’s
recommended to deploy the secret in an additional file like
this:
</para>
<itemizedlist>
<listitem>
<para>
Create a file with the following contents:
</para>
<programlisting>
registration_shared_secret: your-very-secret-secret
</programlisting>
</listitem>
<listitem>
<para>
Deploy the file with a secret-manager such as
<link xlink:href="https://nixops.readthedocs.io/en/latest/overview.html#managing-keys"><option>deployment.keys</option></link>
from
<citerefentry><refentrytitle>nixops</refentrytitle><manvolnum>1</manvolnum></citerefentry>
or
<link xlink:href="https://github.com/Mic92/sops-nix/">sops-nix</link>
to e.g.
<filename>/run/secrets/matrix-shared-secret</filename> and
ensure that it’s readable by
<literal>matrix-synapse</literal>.
</para>
</listitem>
<listitem>
<para>
Include the file like this in your configuration:
</para>
<programlisting>

}
</programlisting>

Riot.im, see the

<para>
The Element developers do not recommend running Element and your

security reasons. In the example, this means that you should not
reuse the <literal>myhostname.example.org</literal> virtualHost
to also serve Element, but instead serve it on a different
subdomain, like <literal>element.example.org</literal> in the
example. See the

<title>Taskserver</title>
<para>
Taskserver is the server component of
<link xlink:href="https://taskwarrior.org/">Taskwarrior</link>, a
free and open source todo list application.
</para>
<para>
<emphasis>Upstream documentation:</emphasis>
<link xlink:href="https://taskwarrior.org/docs/#taskd">https://taskwarrior.org/docs/#taskd</link>
</para>
<section xml:id="module-services-taskserver-configuration">
<title>Configuration</title>
<para>
Taskserver does all of its authentication via TLS using client
certificates, so you either need to roll your own CA or purchase a
certificate from a known CA, which allows creation of client
certificates. These certificates are usually advertised as
<quote>server certificates</quote>.
</para>
<para>
So in order to make it easier to handle your own CA, there is a
helper tool called <command>nixos-taskserver</command> which
manages the custom CA along with Taskserver organisations, users
and groups.
</para>
<para>
While the client certificates in Taskserver only authenticate
whether a user is allowed to connect, every user has its own UUID
which identifies it as an entity.
</para>
<para>
With <command>nixos-taskserver</command> the client certificate is
created along with the UUID of the user, so it handles all of the
credentials needed in order to setup the Taskwarrior client to
work with a Taskserver.
</para>
</section>
<section xml:id="module-services-taskserver-nixos-taskserver-tool">
<title>The nixos-taskserver tool</title>
<para>
Because Taskserver by default only provides scripts to setup users
imperatively, the <command>nixos-taskserver</command> tool is used
for addition and deletion of organisations along with users and
groups defined by
<xref linkend="opt-services.taskserver.organisations" /> and as
well for imperative set up.
</para>
<para>
The tool is designed to not interfere if the command is used to
manually set up some organisations, users or groups.
</para>
<para>
For example if you add a new organisation using
<command>nixos-taskserver org add foo</command>, the organisation
is not modified and deleted no matter what you define in
<option>services.taskserver.organisations</option>, even if you’re
adding the same organisation in that option.
</para>
<para>
The tool is modelled to imitate the official
<command>taskd</command> command, documentation for each
subcommand can be shown by using the <option>--help</option>
switch.
</para>
</section>
<section xml:id="module-services-taskserver-declarative-ca-management">
<title>Declarative/automatic CA management</title>
<para>
Everything is done according to what you specify in the module
options, however in order to set up a Taskwarrior client for
synchronisation with a Taskserver instance, you have to transfer
the keys and certificates to the client machine.
</para>
<para>
This is done using
<command>nixos-taskserver user export $orgname $username</command>
which is printing a shell script fragment to stdout which can
either be used verbatim or adjusted to import the user on the
client machine.
</para>
<para>
For example, let’s say you have the following configuration:
</para>
<programlisting>
{
services.taskserver.enable = true;
services.taskserver.fqdn = &quot;server&quot;;
services.taskserver.listenHost = &quot;::&quot;;
services.taskserver.organisations.my-company.users = [ &quot;alice&quot; ];
}
</programlisting>
<para>
This creates an organisation called <literal>my-company</literal>
with the user <literal>alice</literal>.
</para>
<para>
Now in order to import the <literal>alice</literal> user to
another machine <literal>alicebox</literal>, all we need to do is
something like this:
</para>
<programlisting>
$ ssh server nixos-taskserver user export my-company alice | sh
</programlisting>
<para>
Of course, if no SSH daemon is available on the server you can
also copy &amp; paste it directly into a shell.
</para>
<para>
After this step the user should be set up and you can start
synchronising your tasks for the first time with
<command>task sync init</command> on <literal>alicebox</literal>.
</para>
<para>
Subsequent synchronisation requests merely require the command
<command>task sync</command> after that stage.
</para>
</section>
<section xml:id="module-services-taskserver-manual-ca-management">
<title>Manual CA management</title>
<para>
If you set any options within
<link linkend="opt-services.taskserver.pki.manual.ca.cert">service.taskserver.pki.manual</link>.*,
<command>nixos-taskserver</command> won’t issue certificates, but
you can still use it for adding or removing user accounts.

<link xlink:href="https://domainaware.github.io/parsedmarc/">parsedmarc</link>
is a service which parses incoming
<link xlink:href="https://dmarc.org/">DMARC</link> reports and
stores or sends them to a downstream service for further analysis.
In combination with Elasticsearch, Grafana and the included Grafana
dashboard, it provides a handy overview of DMARC reports over time.
</para>
<section xml:id="module-services-parsedmarc-basic-usage">
<title>Basic usage</title>
<para>
A very minimal setup which reads incoming reports from an external
email address and saves them to a local Elasticsearch instance
looks like this:
</para>
<programlisting language="nix">

Note that GeoIP provisioning is disabled in the example for
simplicity, but should be turned on for fully functional reports.
</para>

<link xlink:href="options.html#opt-services.parsedmarc.provision.localMail.recipientName">services.parsedmarc.provision.localMail.recipientName</link>.
You need to add an MX record pointing to the host. More
concretely: for the example to work, an MX record needs to be set
up for <literal>monitoring.example.com</literal> and the complete
email address that should be configured in the domain’s dmarc
policy is <literal>dmarc@monitoring.example.com</literal>.

Prometheus exporters provide metrics for the
<link xlink:href="https://prometheus.io">prometheus monitoring
system</link>.
</para>
<section xml:id="module-services-prometheus-exporters-configuration">
<title>Configuration</title>
<para>
One of the most common exporters is the
<link xlink:href="https://github.com/prometheus/node_exporter">node
exporter</link>, it provides hardware and OS metrics from the host
it’s running on. The exporter could be configured as follows:
</para>
<programlisting>
services.prometheus.exporters.node = {
enable = true;
port = 9100;
enabledCollectors = [
&quot;logind&quot;
&quot;systemd&quot;
];
disabledCollectors = [
&quot;textfile&quot;
];
openFirewall = true;
firewallFilter = &quot;-i br0 -p tcp -m tcp --dport 9100&quot;;
};
</programlisting>
<para>
It should now serve all metrics from the collectors that are
explicitly enabled and the ones that are
<link xlink:href="https://github.com/prometheus/node_exporter#enabled-by-default">enabled
by default</link>, via http under <literal>/metrics</literal>. In
this example the firewall should just allow incoming connections
to the exporter’s port on the bridge interface
<literal>br0</literal> (this would have to be configured
separately of course). For more information about configuration
see <literal>man configuration.nix</literal> or search through the
<link xlink:href="https://nixos.org/nixos/options.html#prometheus.exporters">available
options</link>.
</para>
<para>
Prometheus can now be configured to consume the metrics produced
by the exporter:
</para>
<programlisting>
services.prometheus = {
# ...
scrapeConfigs = [
{
job_name = &quot;node&quot;;
static_configs = [{
targets = [ &quot;localhost:${toString config.services.prometheus.exporters.node.port}&quot; ];

];
# ...
}

<title>Adding a new exporter</title>
<para>
To add a new exporter, it has to be packaged first (see
<literal>nixpkgs/pkgs/servers/monitoring/prometheus/</literal> for
examples), then a module can be added. The postfix exporter is
used in this example:
</para>
<itemizedlist>
<listitem>
<para>
Some default options for all exporters are provided by
<literal>nixpkgs/nixos/modules/services/monitoring/prometheus/exporters.nix</literal>:

<para>
As there is already a package available, the module can now be
added. This is accomplished by adding a new file to the
<literal>nixos/modules/services/monitoring/prometheus/exporters/</literal>
directory, which will be called postfix.nix and contains all
exporter specific options and configuration:
</para>

# (and optional overrides for default options).
# Note that this attribute is optional.
extraOpts = {
telemetryPath = mkOption {

};
};
# `serviceOpts` is an attribute set which contains configuration
# for the exporter's systemd service. One of
# `serviceOpts.script` and `serviceOpts.serviceConfig.ExecStart`
# has to be specified here. This will be merged with the default

${concatStringsSep &quot; \\\n &quot; cfg.extraFlags}
'';
};
};
}
</programlisting>
</listitem>
<listitem>
<para>
This should already be enough for the postfix exporter.
Additionally one could now add assertions and conditional
default values. This can be done in the
<quote>meta-module</quote> that combines all exporter
definitions and generates the submodules:
<literal>nixpkgs/nixos/modules/services/prometheus/exporters.nix</literal>

important parameters.
</para>
<para>
Single node setup is split into two kinds of options: those that

Options that affect the surroundings of the sync server are
<literal>enableNginx</literal>, <literal>enableTLS</literal> and
<literal>hostnam</literal>. If <literal>enableNginx</literal> is
set the sync server module will automatically add an nginx virtual
host to the system using <literal>hostname</literal> as the domain

<section xml:id="module-services-mosquitto-config">
<title>Configuration</title>
<para>
The Mosquitto configuration has four distinct types of settings:
the global settings of the daemon, listeners, plugins, and
bridges. Bridges and listeners are part of the global
configuration, plugins are part of listeners. Users of the broker
are configured as parts of listeners rather than globally,
allowing configurations in which a given user is only allowed to
log in to the broker using specific listeners (eg to configure an
admin user with full access to all topics, but restricted to
localhost).
</para>
<para>
Almost all options of Mosquitto are available for configuration at
their appropriate levels, some as NixOS options written in camel
case, the remainders under <literal>settings</literal> with their
exact names in the Mosquitto config file. The exceptions are
<literal>acl_file</literal> (which is always set according to the
<literal>acl</literal> attributes of a listener and its users) and
<literal>per_listener_settings</literal> (which is always set to
<literal>true</literal>).
</para>
<section xml:id="module-services-mosquitto-config-passwords">
<title>Password authentication</title>
<para>
Mosquitto can be run in two modes, with a password file or
without. Each listener has its own password file, and different
listeners may use different password files. Password file
generation can be disabled by setting
<literal>omitPasswordAuth = true</literal> for a listener; in
this case it is necessary to either set
<literal>settings.allow_anonymous = true</literal> to allow all
logins, or to configure other authentication methods like TLS
client certificates with
<literal>settings.use_identity_as_username = true</literal>.
</para>
<para>
The default is to generate a password file for each listener
from the users configured to that listener. Users with no
configured password will not be added to the password file and
thus will not be able to use the broker.

<section xml:id="module-services-mosquitto-config-acl">

Every listener has a Mosquitto <literal>acl_file</literal>

config:
</para>
<itemizedlist spacing="compact">
<listitem>
<para>
the <literal>acl</literal> attribute of the listener
configures pattern ACL entries and topic ACL entries for

</listitem>
<listitem>
<para>
the <literal>acl</literal> attribute of every user

setting, so no prefix is required or allowed.
</para>
</listitem>
</itemizedlist>
<para>
The default ACL for a listener is empty, disallowing all
accesses from all clients. To configure a completely open ACL,
set <literal>acl = [ &quot;pattern readwrite #&quot; ]</literal>

open-source, modern XMPP server.

<section xml:id="module-services-prosody-basic-usage">
<title>Basic usage</title>
<para>
A common struggle for most XMPP newcomers is to find the right set
of XMPP Extensions (XEPs) to setup. Forget to activate a few of
those and your XMPP experience might turn into a nightmare!
</para>
<para>
The XMPP community tackles this problem by creating a meta-XEP
listing a decent set of XEPs you should implement. This meta-XEP
is issued every year, the 2020 edition being
<link xlink:href="https://xmpp.org/extensions/xep-0423.html">XEP-0423</link>.
</para>
<para>
The NixOS Prosody module will implement most of these recommendend
XEPs out of the box. That being said, two components still require
some manual configuration: the
<link xlink:href="https://xmpp.org/extensions/xep-0045.html">Multi
User Chat (MUC)</link> and the
<link xlink:href="https://xmpp.org/extensions/xep-0363.html">HTTP
File Upload</link> ones. You’ll need to create a DNS subdomain for
each of those. The current convention is to name your MUC endpoint
<literal>conference.example.org</literal> and your HTTP upload
domain <literal>upload.example.org</literal>.
</para>
<para>
A good configuration to start with, including a
<link xlink:href="https://xmpp.org/extensions/xep-0045.html">Multi
User Chat (MUC)</link> endpoint as well as a
<link xlink:href="https://xmpp.org/extensions/xep-0363.html">HTTP
File Upload</link> endpoint will look like this:
</para>
<programlisting>
services.prosody = {

<section xml:id="module-services-prosody-letsencrypt">
<title>Let’s Encrypt Configuration</title>
<para>
As you can see in the code snippet from the
<link linkend="module-services-prosody-basic-usage">previous
section</link>, you’ll need a single TLS certificate covering your
main endpoint, the MUC one as well as the HTTP Upload one. We can
generate such a certificate by leveraging the ACME
<link linkend="opt-security.acme.certs._name_.extraDomainNames">extraDomainNames</link>
module option.
</para>
<para>
Provided the setup detailed in the previous section, you’ll need
the following acme configuration to generate a TLS certificate for
the three endponits:

email = &quot;root@example.org&quot;;
acceptTerms = true;
certs = {
&quot;example.org&quot; = {

<title>Federation policies</title>
<para>
Akkoma comes with a number of modules to police federation with
other ActivityPub instances. The most valuable for typical users
is the
<link xlink:href="https://docs.akkoma.dev/stable/configuration/cheatsheet/#mrf_simple"><literal>:mrf_simple</literal></link>
module which allows limiting federation based on instance
hostnames.
</para>
<para>
This configuration snippet provides an example on how these can be
used. Choosing an adequate federation policy is not trivial and
entails finding a balance between connectivity to the rest of the

Pleroma instances can be migrated to Akkoma either by copying the
database and upload data or by pointing Akkoma to the existing
data. The necessary database migrations are run automatically
during startup of the service.
</para>
<para>
The configuration has to be copy‐edited manually.
</para>
<para>
Depending on the size of the database, the initial migration may
take a long time and exceed the startup timeout of the system
manager. To work around this issue one may adjust the startup
timeout
<option>systemd.services.akkoma.serviceConfig.TimeoutStartSec</option>
or simply run the migrations manually:

<section xml:id="modules-services-akkoma-migration-pleroma-copy">
<title>Copying data</title>
<para>
Copying the Pleroma data instead of re‐using it in place may
permit easier reversion to Pleroma, but allows the two data sets
to diverge.
</para>
<para>
First disable Pleroma and then copy its database and upload
data:
</para>
<programlisting>
# Create a copy of the database
nix-shell -p postgresql --run 'createdb -T pleroma akkoma'
# Copy upload data
mkdir /var/lib/akkoma
cp -R --reflink=auto /var/lib/pleroma/uploads /var/lib/akkoma/
</programlisting>
<para>
After the data has been copied, enable the Akkoma service and
verify that the migration has been successful. If no longer
required, the original data may then be deleted:
</para>
<programlisting>
# Delete original database
nix-shell -p postgresql --run 'dropdb pleroma'
# Delete original Pleroma state
rm -r /var/lib/pleroma
</programlisting>
</section>
<section xml:id="modules-services-akkoma-migration-pleroma-reuse">
<title>Re‐using data</title>
<para>
To re‐use the Pleroma data in place, disable Pleroma and enable
Akkoma, pointing it to the Pleroma database and upload
directory.

<para>
Please keep in mind that after the Akkoma service has been

<para>
A minimal configuration using Let’s Encrypt for TLS certificates
looks like this:
</para>
<programlisting>

<section xml:id="module-services-discourse-tls">
<title>Using a regular TLS certificate</title>
<para>
To set up TLS using a regular certificate and key on file, use the

options:
</para>
<programlisting>

</section>
<section xml:id="module-services-discourse-database">
<title>Database access</title>
<para>
Discourse uses PostgreSQL to store most of its data. A database
will automatically be enabled and a database and role created
unless <xref linkend="opt-services.discourse.database.host" /> is
changed from its default of <literal>null</literal> or
<xref linkend="opt-services.discourse.database.createLocally" />
is set to <literal>false</literal>.
</para>
<para>
External database access can also be configured by setting
<xref linkend="opt-services.discourse.database.host" />,
<xref linkend="opt-services.discourse.database.username" /> and
<xref linkend="opt-services.discourse.database.passwordFile" /> as
appropriate. Note that you need to manually create a database
called <literal>discourse</literal> (or the name you chose in
<xref linkend="opt-services.discourse.database.name" />) and allow
the configured database user full access to it.
</para>
</section>
<section xml:id="module-services-discourse-mail">
<title>Email</title>
<para>
In addition to the basic setup, you’ll want to configure an SMTP
server Discourse can use to send user registration and password
reset emails, among others. You can also optionally let Discourse
receive email, which enables people to reply to threads and
conversations via email.
</para>
<para>
A basic setup which assumes you want to use your configured
<link linkend="opt-services.discourse.hostname">hostname</link> as
email domain can be done like this:
</para>
<programlisting>
services.discourse = {
enable = true;
hostname = &quot;discourse.example.com&quot;;
sslCertificate = &quot;/path/to/ssl_certificate&quot;;
sslCertificateKey = &quot;/path/to/ssl_certificate_key&quot;;
admin = {
email = &quot;admin@example.com&quot;;
username = &quot;admin&quot;;
fullName = &quot;Administrator&quot;;
passwordFile = &quot;/path/to/password_file&quot;;
};
mail.outgoing = {
serverAddress = &quot;smtp.emailprovider.com&quot;;
port = 587;
username = &quot;user@emailprovider.com&quot;;
passwordFile = &quot;/path/to/smtp_password_file&quot;;
};
mail.incoming.enable = true;
secretKeyBaseFile = &quot;/path/to/secret_key_base_file&quot;;
};
</programlisting>
<para>
This assumes you have set up an MX record for the address you’ve
set in
<link linkend="opt-services.discourse.hostname">hostname</link>
and requires proper SPF, DKIM and DMARC configuration to be done
for the domain you’re sending from, in order for email to be
reliably delivered.
</para>
<para>
If you want to use a different domain for your outgoing email (for
example <literal>example.com</literal> instead of
<literal>discourse.example.com</literal>) you should set
<xref linkend="opt-services.discourse.mail.notificationEmailAddress" />
and
<xref linkend="opt-services.discourse.mail.contactEmailAddress" />
manually.
</para>
<note>
<para>
Setup of TLS for incoming email is currently only configured
automatically when a regular TLS certificate is used, i.e. when
<xref linkend="opt-services.discourse.sslCertificate" /> and
<xref linkend="opt-services.discourse.sslCertificateKey" /> are
set.
</para>
</note>

</para>
<para>
Settings containing secret data should be set to an attribute
set containing the attribute <literal>_secret</literal> - a

<section xml:id="module-services-discourse-plugins">
<title>Plugins</title>
<para>
You can install Discourse plugins using the
<xref linkend="opt-services.discourse.plugins" /> option.
Pre-packaged plugins are provided in
<literal>&lt;your_discourse_package_here&gt;.plugins</literal>. If
you want the full suite of plugins provided through
<literal>nixpkgs</literal>, you can also set the
<xref linkend="opt-services.discourse.package" /> option to
<literal>pkgs.discourseAllPlugins</literal>.
</para>
<para>
Plugins can be built with the
<literal>&lt;your_discourse_package_here&gt;.mkDiscoursePlugin</literal>
function. Normally, it should suffice to provide a
<literal>name</literal> and <literal>src</literal> attribute. If
the plugin has Ruby dependencies, however, they need to be
packaged in accordance with the
<link xlink:href="https://nixos.org/manual/nixpkgs/stable/#developing-with-ruby">Developing
with Ruby</link> section of the Nixpkgs manual and the appropriate
gem options set in <literal>bundlerEnvArgs</literal> (normally
<literal>gemdir</literal> is sufficient). A plugin’s Ruby
dependencies are listed in its <filename>plugin.rb</filename> file
as function calls to <literal>gem</literal>. To construct the
corresponding <filename>Gemfile</filename> manually, run
<command>bundle init</command>, then add the
<literal>gem</literal> lines to it verbatim.
</para>
<para>
Much of the packaging can be done automatically by the
<filename>nixpkgs/pkgs/servers/web-apps/discourse/update.py</filename>
script - just add the plugin to the <literal>plugins</literal>
list in the <literal>update_plugins</literal> function and run the
script:
</para>
<programlisting language="bash">
./update.py update-plugins
</programlisting>
<para>
Some plugins provide
<link linkend="module-services-discourse-site-settings">site
settings</link>. Their defaults can be configured using
<xref linkend="opt-services.discourse.siteSettings" />, just like
regular site settings. To find the names of these settings, look
in the <literal>config/settings.yml</literal> file of the plugin
repo.
</para>
<para>
For example, to add the
<link xlink:href="https://github.com/discourse/discourse-spoiler-alert">discourse-spoiler-alert</link>
and
<link xlink:href="https://github.com/discourse/discourse-solved">discourse-solved</link>

<title>Matomo</title>
<para>
Matomo is a real-time web analytics application. This module
configures php-fpm as backend for Matomo, optionally configuring an
nginx vhost as well.
</para>
<para>
An automatic setup is not suported by Matomo, so you need to
configure Matomo itself in the browser-based Matomo setup.
</para>
<section xml:id="module-services-matomo-database-setup">
<title>Database Setup</title>
<para>
You also need to configure a MariaDB or MySQL database and -user
for Matomo yourself, and enter those credentials in your browser.
You can use passwordless database authentication via the
UNIX_SOCKET authentication plugin with the following SQL commands:
</para>
<programlisting>
# For MariaDB
INSTALL PLUGIN unix_socket SONAME 'auth_socket';
CREATE DATABASE matomo;
CREATE USER 'matomo'@'localhost' IDENTIFIED WITH unix_socket;
GRANT ALL PRIVILEGES ON matomo.* TO 'matomo'@'localhost';
# For MySQL
INSTALL PLUGIN auth_socket SONAME 'auth_socket.so';
CREATE DATABASE matomo;
CREATE USER 'matomo'@'localhost' IDENTIFIED WITH auth_socket;
GRANT ALL PRIVILEGES ON matomo.* TO 'matomo'@'localhost';
</programlisting>
<para>
Then fill in <literal>matomo</literal> as database user and
database name, and leave the password field blank. This
authentication works by allowing only the
<literal>matomo</literal> unix user to authenticate as the
<literal>matomo</literal> database user (without needing a
password), but no other users. For more information on
passwordless login, see
<link xlink:href="https://mariadb.com/kb/en/mariadb/unix_socket-authentication-plugin/">https://mariadb.com/kb/en/mariadb/unix_socket-authentication-plugin/</link>.

Of course, you can use password based authentication as well, e.g.
when the database is not on the same host.

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
<filename>/var/lib/nextcloud/config/override.config.php</filename>
which is generated by the module and linked from the store to
ensure that all values from <filename>config.php</filename>
can be modified by the module. However
<filename>config.php</filename> manages the application’s
state and shouldn’t be touched manually because of that.

Nextcloud doesn’t allow to move more than one major-version

upgrade to <literal>v18</literal>, you need to upgrade to
<literal>v17</literal> first. This is ensured automatically as
long as the
<link linkend="opt-system.stateVersion">stateVersion</link> is
declared properly. In that case the oldest version available
(one major behind the one from the previous NixOS release)
will be selected by default and the module will generate a

If this occurs on an <emphasis>existing</emphasis> setup,
this is most likely because the maintenance mode is

<title>Maintainer information</title>
<para>
As stated in the previous paragraph, we must provide a clean
upgrade-path for Nextcloud since it cannot move more than one
major version forward on a single upgrade. This chapter adds some
notes how Nextcloud updates should be rolled out in the future.
</para>
<para>
While minor and patch-level updates are no problem and can be done
directly in the package-expression (and should be backported to
supported stable branches after that), major-releases should be
added in a new attribute (e.g. Nextcloud
<literal>v19.0.0</literal> should be available in
<literal>nixpkgs</literal> as
<literal>pkgs.nextcloud19</literal>). To provide simple upgrade
paths it’s generally useful to backport those as well to stable
branches. As long as the package-default isn’t altered, this won’t
break existing setups. After that, the versioning-warning in the
<literal>nextcloud</literal>-module should be updated to make sure
that the
<link linkend="opt-services.nextcloud.package">package</link>-option
selects the latest version on fresh setups.
</para>
<para>
If major-releases will be abandoned by upstream, we should check
first if those are needed in NixOS for a safe upgrade-path before
removing those. In that case we should keep those packages, but
mark them as insecure in an expression like this (in
<literal>&lt;nixpkgs/pkgs/servers/nextcloud/default.nix&gt;</literal>):
</para>
<programlisting>
/* ... */
{
nextcloud17 = generic {
version = &quot;17.0.x&quot;;
sha256 = &quot;0000000000000000000000000000000000000000000000000000&quot;;
eol = true;
};
}
</programlisting>
<para>
Ideally we should make sure that it’s possible to jump two NixOS
versions forward: i.e. the warnings and the logic in the module
should guard a user to upgrade from a Nextcloud on e.g. 19.09 to a
Nextcloud on 20.09.

Majority of software building on the GNOME platform use GLib’s

backend, where the values of the settings are stored. On NixOS,
like on most Linux distributions, dconf database is used as the
backend.

<para>
Overrides really only change the default values for GSettings
keys so if you or an application changes the setting value, the
value set by the override will be ignored. Until

<title>Pantheon Desktop</title>
<para>
Pantheon is the desktop environment created for the elementary OS
distribution. It is written from scratch in Vala, utilizing GNOME
technologies with GTK and Granite.
</para>
<section xml:id="sec-pantheon-enable">
<title>Enabling Pantheon</title>
<para>
All of Pantheon is working in NixOS and the applications should be
available, aside from a few
<link xlink:href="https://github.com/NixOS/nixpkgs/issues/58161">exceptions</link>.
To enable Pantheon, set
</para>
<programlisting>
services.xserver.desktopManager.pantheon.enable = true;
</programlisting>
<para>
This automatically enables LightDM and Pantheon’s LightDM greeter.
If you’d like to disable this, set
</para>
<programlisting>
services.xserver.displayManager.lightdm.greeters.pantheon.enable = false;
services.xserver.displayManager.lightdm.enable = false;
</programlisting>
<para>
but please be aware using Pantheon without LightDM as a display
manager will break screenlocking from the UI. The NixOS module for
Pantheon installs all of Pantheon’s default applications. If you’d
like to not install Pantheon’s apps, set
</para>
<programlisting>
services.pantheon.apps.enable = false;
</programlisting>
<para>
You can also use
<xref linkend="opt-environment.pantheon.excludePackages" /> to
remove any other app (like <literal>elementary-mail</literal>).
</para>
</section>
<section xml:id="sec-pantheon-wingpanel-switchboard">
<title>Wingpanel and Switchboard plugins</title>
<para>
Wingpanel and Switchboard work differently than they do in other
distributions, as far as using plugins. You cannot install a
plugin globally (like with
<option>environment.systemPackages</option>) to start using it.
You should instead be using the following options:
</para>
<itemizedlist spacing="compact">
<listitem>
<para>
<xref linkend="opt-services.xserver.desktopManager.pantheon.extraWingpanelIndicators" />
</para>
</listitem>
<listitem>
<para>
<xref linkend="opt-services.xserver.desktopManager.pantheon.extraSwitchboardPlugs" />
</para>
</listitem>
</itemizedlist>
<para>
to configure the programs with plugs or indicators.
</para>
<para>
The difference in NixOS is both these programs are patched to load
plugins from a directory that is the value of an environment
variable. All of which is controlled in Nix. If you need to
configure the particular packages manually you can override the
packages like:
</para>
<programlisting>
wingpanel-with-indicators.override {
indicators = [
pkgs.some-special-indicator
];
};
switchboard-with-plugs.override {
plugs = [
pkgs.some-special-plug
];
};
</programlisting>
<para>
please note that, like how the NixOS options describe these as
extra plugins, this would only add to the default plugins included
with the programs. If for some reason you’d like to configure
which plugins to use exactly, both packages have an argument for
this:
</para>
<programlisting>
wingpanel-with-indicators.override {
useDefaultIndicators = false;
indicators = specialListOfIndicators;
};
switchboard-with-plugs.override {
useDefaultPlugs = false;
plugs = specialListOfPlugs;
};
</programlisting>
<para>
this could be most useful for testing a particular plug-in in
isolation.

currently. See this

<title>External Bootloader Backends</title>
<para>
NixOS has support for several bootloader backends by default:
systemd-boot, grub, uboot, etc. The built-in bootloader backend
support is generic and supports most use cases. Some users may
prefer to create advanced workflows around managing the bootloader
and bootable entries.
</para>
<para>
You can replace the built-in bootloader support with your own
tooling using the <quote>external</quote> bootloader option.
</para>
<para>
Imagine you have created a new package called FooBoot. FooBoot
provides a program at
<literal>${pkgs.fooboot}/bin/fooboot-install</literal> which takes
the system closure’s path as its only argument and configures the
system’s bootloader.
</para>
<para>
You can enable FooBoot like this:
</para>
<programlisting language="nix">
{ pkgs, ... }: {
boot.loader.external = {
enable = true;
installHook = &quot;${pkgs.fooboot}/bin/fooboot-install&quot;;
};
}

<title>Developing Custom Bootloader Backends</title>

Bootspec format and synthesis tools to identify the key properties
for bootable system generations.
