Continuwuity doesn't support horizontal scalability or distributed loading
|
||||
natively. However, a community-maintained Helm Chart is available here to run
|
||||
Continuwuity on Kubernetes: <https://gitlab.cronce.io/charts/conduwuit>
|
||||
conduwuit on Kubernetes: <https://gitlab.cronce.io/charts/conduwuit>
|
||||
|
||||
This should be compatible with Continuwuity, but you will need to change the image reference.

# Continuwuity for NixOS
|
||||
|
||||
You can acquire Continuwuity with Nix (or [Lix][lix]) from various places:
|
||||
NixOS packages Continuwuity as `matrix-continuwuity`. This package includes both the Continuwuity software and a dedicated NixOS module for configuration and deployment.
|
||||
|
||||
* The `flake.nix` at the root of the repo
|
||||
* The `default.nix` at the root of the repo
|
||||
* From Continuwuity's binary cache
|
||||
## Installation methods
|
||||
|
||||
### NixOS module
|
||||
You can acquire Continuwuity with Nix (or [Lix][lix]) from these sources:
|
||||
|
||||
The `flake.nix` and `default.nix` do not currently provide a NixOS module (contributions
|
||||
welcome!), so you can use [`services.matrix-conduit`][module] from Nixpkgs to configure
|
||||
Continuwuity.
|
||||
* Directly from Nixpkgs using the official package (`pkgs.matrix-continuwuity`)
|
||||
* The `flake.nix` at the root of the Continuwuity repo
|
||||
* The `default.nix` at the root of the Continuwuity repo
|
||||
|
||||
### Conduit NixOS Config Module and SQLite
|
||||
## NixOS module
|
||||
|
||||
Beware! The [`services.matrix-conduit`][module] module defaults to SQLite as a database backend.
|
||||
Continuwuity dropped SQLite support in favor of exclusively supporting the much faster RocksDB.
|
||||
Make sure you are using the RocksDB backend before migrating!
|
||||
Continuwuity now has an official NixOS module that simplifies configuration and deployment. The module is available in Nixpkgs as `services.matrix-continuwuity` from NixOS 25.05.
|
||||
|
||||
There is a [tool to migrate a Conduit SQLite database to
|
||||
RocksDB](https://github.com/ShadowJonathan/conduit_toolbox/).
|
||||
Here's a basic example of how to use the module:
|
||||
|
||||
If you want to run the latest code, get Continuwuity from the `flake.nix`
|
||||
or `default.nix` and set [`services.matrix-conduit.package`][package]
|
||||
appropriately to use Continuwuity instead of Conduit.
|
||||
```nix
|
||||
{ config, pkgs, ... }:
|
||||
|
||||
{
|
||||
services.matrix-continuwuity = {
|
||||
enable = true;
|
||||
settings = {
|
||||
global = {
|
||||
server_name = "example.com";
|
||||
# Listening on localhost by default
|
||||
# address and port are handled automatically
|
||||
allow_registration = false;
|
||||
allow_encryption = true;
|
||||
allow_federation = true;
|
||||
trusted_servers = [ "matrix.org" ];
|
||||
};
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Available options
|
||||
|
||||
The NixOS module provides these configuration options:
|
||||
|
||||
- `enable`: Enable the Continuwuity service
|
||||
- `user`: The user to run Continuwuity as (defaults to "continuwuity")
|
||||
- `group`: The group to run Continuwuity as (defaults to "continuwuity")
|
||||
- `extraEnvironment`: Extra environment variables to pass to the Continuwuity server
|
||||
- `package`: The Continuwuity package to use
|
||||
- `settings`: The Continuwuity configuration (in TOML format)
|
||||
|
||||
Use the `settings` option to configure Continuwuity itself. See the [example configuration file](../configuration/examples.md#example-configuration) for all available options.
|
||||
|
||||
### UNIX sockets
|
||||
|
||||
Due to the lack of a Continuwuity NixOS module, when using the `services.matrix-conduit` module,
|
||||
a workaround like the one below is necessary to use UNIX sockets. This is because the UNIX
|
||||
socket option does not exist in Conduit, and the module forcibly sets the `address` and
|
||||
`port` config options.
|
||||
The NixOS module natively supports UNIX sockets through the `global.unix_socket_path` option. When using UNIX sockets, set `global.address` to `null`:
|
||||
|
||||
```nix
|
||||
options.services.matrix-conduit.settings = lib.mkOption {
|
||||
apply = old: old // (
|
||||
if (old.global ? "unix_socket_path")
|
||||
then { global = builtins.removeAttrs old.global [ "address" "port" ]; }
|
||||
else { }
|
||||
);
|
||||
services.matrix-continuwuity = {
|
||||
enable = true;
|
||||
settings = {
|
||||
global = {
|
||||
server_name = "example.com";
|
||||
address = null; # Must be null when using unix_socket_path
|
||||
unix_socket_path = "/run/continuwuity/continuwuity.sock";
|
||||
unix_socket_perms = 660; # Default permissions for the socket
|
||||
# ...
|
||||
};
|
||||
};
|
||||
};
|
||||
|
||||
```
|
||||
|
||||
Additionally, the [`matrix-conduit` systemd unit][systemd-unit] in the module does not allow
|
||||
the `AF_UNIX` socket address family in its systemd unit's `RestrictAddressFamilies=`. This
|
||||
disallows the namespace from accessing or creating UNIX sockets and must be enabled like this:
|
||||
The module automatically sets the correct `RestrictAddressFamilies` in the systemd service configuration to allow access to UNIX sockets.
|
||||
|
||||
```nix
|
||||
systemd.services.conduit.serviceConfig.RestrictAddressFamilies = [ "AF_UNIX" ];
|
||||
```
|
||||
### RocksDB database
|
||||
|
||||
Although these workarounds are feasible, a dedicated Continuwuity NixOS configuration module, developed and
|
||||
published by the community, would be appreciated.
|
||||
Continuwuity exclusively uses RocksDB as its database backend. The system configures the database path automatically to `/var/lib/continuwuity/` and you cannot change it due to the service's reliance on systemd's StateDir.
|
||||
|
||||
If you're migrating from Conduit with SQLite, use this [tool to migrate a Conduit SQLite database to RocksDB](https://github.com/ShadowJonathan/conduit_toolbox/).
|
||||
|
||||
### jemalloc and hardened profile
|
||||
|
||||
Continuwuity uses jemalloc by default. This may interfere with the [`hardened.nix` profile][hardened.nix]
|
||||
because it uses `scudo` by default. You must either disable/hide `scudo` from Continuwuity or
|
||||
disable jemalloc like this:
|
||||
Continuwuity uses jemalloc by default. This may interfere with the [`hardened.nix` profile][hardened.nix] because it uses `scudo` by default. Either disable/hide `scudo` from Continuwuity or disable jemalloc like this:
|
||||
|
||||
```nix
|
||||
let
|
||||
conduwuit = pkgs.unstable.conduwuit.override {
|
||||
enableJemalloc = false;
|
||||
};
|
||||
in
|
||||
services.matrix-continuwuity = {
|
||||
enable = true;
|
||||
package = pkgs.matrix-continuwuity.override {
|
||||
enableJemalloc = false;
|
||||
};
|
||||
# ...
|
||||
};
|
||||
```
|
||||
|
||||
## Upgrading from Conduit
|
||||
|
||||
If you previously used Conduit with the `services.matrix-conduit` module:
|
||||
|
||||
1. Ensure your Conduit uses the RocksDB backend, or migrate from SQLite using the [migration tool](https://github.com/ShadowJonathan/conduit_toolbox/)
|
||||
2. Switch to the new module by changing `services.matrix-conduit` to `services.matrix-continuwuity` in your configuration
|
||||
3. Update any custom configuration to match the new module's structure
|
||||
|
||||
## Reverse proxy configuration
|
||||
|
||||
You'll need to set up a reverse proxy (like nginx or caddy) to expose Continuwuity to the internet. Configure your reverse proxy to forward requests to `/_matrix` on port 443 and 8448 to your Continuwuity instance.
|
||||
|
||||
Here's an example nginx configuration:
|
||||
|
||||
```nginx
|
||||
server {
|
||||
listen 443 ssl;
|
||||
listen [::]:443 ssl;
|
||||
listen 8448 ssl;
|
||||
listen [::]:8448 ssl;
|
||||
|
||||
server_name example.com;
|
||||
|
||||
# SSL configuration here...
|
||||
|
||||
location /_matrix/ {
|
||||
proxy_pass http://127.0.0.1:6167$request_uri;
|
||||
proxy_set_header Host $host;
|
||||
proxy_set_header X-Real-IP $remote_addr;
|
||||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||||
proxy_set_header X-Forwarded-Proto $scheme;
|
||||
}
|
||||
}
|
||||
