# Synapse Guest Module
|
|
|
|
A [pluggable synapse module](https://element-hq.github.io/synapse/latest/modules/index.html) to restrict the actions of guests.
|
|
|
|
**Features:**
|
|
|
|
1. Provides an endpoint that creates temporary users with a same pattern (default: `guest-[randomstring]`).
|
|
2. The temporary users have a mandatory displayname suffix (default: ` (Guest)`) that they can't remove from their profile.
|
|
3. The temporary users are limited in what they can do (examples: create room, invite users).
|
|
4. The temporary users won't be returned by the user directory search results.
|
|
5. The temporary users are disabled after an expiration timeout (default: `24 hours`).
|
|
|
|
## Synapse configuration
|
|
|
|
This modules requires that the homeserver has the following configuration in their `homeserver.yaml`:
|
|
|
|
```yaml
|
|
# Required so Element is able to show the room preview where the user can login.
|
|
allow_guest_access: true
|
|
```
|
|
|
|
## Module installation
|
|
|
|
Copy the `synapse_guest_module` folder into the python modules path.
|
|
This can also be achieved by the [`PYTHONPATH` environment variable](https://docs.python.org/3/using/cmdline.html#envvar-PYTHONPATH).
|
|
|
|
Add module configuration into `modules` section of `homeserver.yaml`:
|
|
|
|
```yaml
|
|
modules:
|
|
- module: synapse_guest_module.GuestModule
|
|
config: {}
|
|
```
|
|
|
|
## Module configuration
|
|
|
|
The module provides (optional) configuration options:
|
|
|
|
- `user_id_prefix` - the prefix of the usernames that are created by this module. Default: `guest-`.
|
|
- `display_name_suffix` - the suffix added to the display name of guest users. Default: ` (Guest)`.
|
|
- `enable_user_reaper` - if true, the module disables all users that are older than the configured expiration time. Default: `true`.
|
|
- `user_expiration_seconds` - the expiration time in seconds when a guest user expires after their creation. Default: `86400` (=24 hours).
|
|
|
|
Example configuration:
|
|
|
|
```yaml
|
|
modules:
|
|
- module: synapse_guest_module.GuestModule
|
|
config:
|
|
# Use a german suffix
|
|
display_name_suffix: " (Gast)"
|
|
```
|
|
|
|
## Production installation
|
|
|
|
The module is not published to a python registry, but we provide a docker container that can be used as an `initContainer` in Kubernetes:
|
|
|
|
```diff
|
|
apiVersion: apps/v1
|
|
kind: "StatefulSet"
|
|
metadata:
|
|
name: synapse
|
|
spec:
|
|
# ...
|
|
template:
|
|
spec:
|
|
+ # The init container copies the module to he `synapse-modules` volume
|
|
+ initContainers:
|
|
+ - image: ghcr.io/element-hq/synapse-guest-module:<version>
|
|
+ name: install-guest-module
|
|
+ volumeMounts:
|
|
+ - mountPath: /modules
|
|
+ name: synapse-modules
|
|
containers:
|
|
- name: "synapse"
|
|
image: "matrixdotorg/synapse:v1.87.0"
|
|
+ env:
|
|
+ # Tell python to read the modules from the `/modules` directory
|
|
+ - name: PYTHONPATH
|
|
+ value: /modules
|
|
+ volumeMounts:
|
|
+ # Mount the `synapse-modules` volume
|
|
+ - mountPath: /modules
|
|
+ name: synapse-modules
|
|
# ...
|
|
+ # Use a local volume to store the module
|
|
+ volumes:
|
|
+ - emptyDir:
|
|
+ medium: Memory
|
|
+ sizeLimit: 50Mi
|
|
+ name: synapse-modules
