reduce scope of nixos documentation
There are so many ways to do this we realistically shouldn't bother describing any of them, especially because people should be learning all the options and choosing the one that suits them best anyway.

# Conduit for Nix/NixOS
|
|
||||||
|
|
||||||
This guide assumes you have a recent version of Nix (^2.4) installed.
|
|
||||||
|
|
||||||
Since Conduit ships as a Nix flake, you'll first need to [enable
|
|
||||||
flakes][enable_flakes].
|
|
||||||
|
|
||||||
You can now use the usual Nix commands to interact with Conduit's flake. For
|
|
||||||
example, `nix run gitlab:famedly/conduit` will run Conduit (though you'll need
|
|
||||||
to provide configuration and such manually as usual).
|
|
||||||
|
|
||||||
If your NixOS configuration is defined as a flake, you can depend on this flake
|
|
||||||
to provide a more up-to-date version than provided by `nixpkgs`. In your flake,
|
|
||||||
add the following to your `inputs`:
|
|
||||||
|
|
||||||
```nix
|
|
||||||
conduit = {
|
|
||||||
url = "gitlab:famedly/conduit";
|
|
||||||
|
|
||||||
# Assuming you have an input for nixpkgs called `nixpkgs`. If you experience
|
|
||||||
# build failures while using this, try commenting/deleting this line. This
|
|
||||||
# will probably also require you to always build from source.
|
|
||||||
inputs.nixpkgs.follows = "nixpkgs";
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
Next, make sure you're passing your flake inputs to the `specialArgs` argument
|
|
||||||
of `nixpkgs.lib.nixosSystem` [as explained here][specialargs]. This guide will
|
|
||||||
assume you've named the group `flake-inputs`.
|
|
||||||
|
|
||||||
Now you can configure Conduit and a reverse proxy for it. Add the following to
|
|
||||||
a new Nix file and include it in your configuration:
|
|
||||||
|
|
||||||
```nix
|
|
||||||
{ config
|
|
||||||
, pkgs
|
|
||||||
, flake-inputs
|
|
||||||
, ...
|
|
||||||
}:
|
|
||||||
|
|
||||||
let
|
|
||||||
# You'll need to edit these values
|
|
||||||
|
|
||||||
# The hostname that will appear in your user and room IDs
|
|
||||||
server_name = "example.com";
|
|
||||||
|
|
||||||
# The hostname that Conduit actually runs on
|
|
||||||
#
|
|
||||||
# This can be the same as `server_name` if you want. This is only necessary
|
|
||||||
# when Conduit is running on a different machine than the one hosting your
|
|
||||||
# root domain. This configuration also assumes this is all running on a single
|
|
||||||
# machine, some tweaks will need to be made if this is not the case.
|
|
||||||
matrix_hostname = "matrix.${server_name}";
|
|
||||||
|
|
||||||
# An admin email for TLS certificate notifications
|
|
||||||
admin_email = "admin@${server_name}";
|
|
||||||
|
|
||||||
# These ones you can leave alone
|
|
||||||
|
|
||||||
# Build a dervation that stores the content of `${server_name}/.well-known/matrix/server`
|
|
||||||
well_known_server = pkgs.writeText "well-known-matrix-server" ''
|
|
||||||
{
|
|
||||||
"m.server": "${matrix_hostname}"
|
|
||||||
}
|
|
||||||
'';
|
|
||||||

||||||

|
|
||||||
well_known_client = pkgs.writeText "well-known-matrix-client" ''
|

# Conduit for NixOS
|
||||||
|
|
||||||
|
Conduit can be acquired by Nix from various places:
|
||||||
|
|
||||||
|
* The `flake.nix` at the root of the repo
|
||||||
|
* The `default.nix` at the root of the repo
|
||||||
|
* From Nixpkgs
|
||||||
|
|
||||||
|
The `flake.nix` and `default.nix` do not (currently) provide a NixOS module, so
|
||||||
|
(for now) [`services.matrix-conduit`][module] from Nixpkgs should be used to
|
||||||
|
configure Conduit.
|
||||||
|
|
||||||
|
If you want to run the latest code, you should get Conduit from the `flake.nix`
|
||||||
|
or `default.nix` and set [`services.matrix-conduit.package`][package]
|
||||||
|
appropriately.
|
||||||
