People should be made aware of the status of this component as soon as possible. This is consitent with the positioning of Note messages we have for other deprecated components (e.g. bot-chatgpt, bot-go-neb, etc). Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3735

# Setting up the Sliding Sync proxy (optional)
|
|
|
|
**Note**: The sliding-sync proxy is **not required** anymore as it's been replaced with a different method (called Simplified Sliding Sync) which is integrated into newer homeservers by default (**Conduit** homeserver from version `0.6.0` or **Synapse** from version `1.114`). This component and documentation remain here for historical purposes, but **installing this old sliding-sync proxy is generally not recommended anymore**.
|
|
|
|
The playbook can install and configure [sliding-sync](https://github.com/matrix-org/sliding-sync) proxy for you.
|
|
|
|
Sliding Sync is an implementation of [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/blob/kegan/sync-v3/proposals/3575-sync.md) and a prerequisite for running the new (**still beta**) Element X clients ([Element X iOS](https://github.com/element-hq/element-x-ios) and [Element X Android](https://github.com/element-hq/element-x-android)).
|
|
|
|
See the project's [documentation](https://github.com/matrix-org/sliding-sync) to learn more.
|
|
|
|
Element X iOS is [available on TestFlight](https://testflight.apple.com/join/uZbeZCOi).
|
|
|
|
Element X Android is [available on the Github Releases page](https://github.com/element-hq/element-x-android/releases).
|
|
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable Sliding Sync proxy, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
matrix_sliding_sync_enabled: true
|
|
```
|
|
|
|
### Adjusting the Sliding Sync proxy URL
|
|
|
|
By default, this playbook installs the Sliding Sync proxy on the `matrix.` subdomain, at the `/sliding-sync` path (https://matrix.example.com/sliding-sync). This makes it easy to install it, because it **doesn't require additional DNS records to be set up**. If that's okay, you can skip this section.
|
|
|
|
By tweaking the `matrix_sliding_sync_hostname` and `matrix_sliding_sync_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
|
|
|
|
Example additional configuration for your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
# Change the default hostname and path prefix
|
|
matrix_sliding_sync_hostname: ss.example.com
|
|
matrix_sliding_sync_path_prefix: /
|
|
```
|
|
|
|
## Adjusting DNS records
|
|
|
|
If you've changed the default hostname, **you may need to adjust your DNS** records to point the Honoroit domain to the Matrix server.
|
|
|
|
See [Configuring DNS](configuring-dns.md) for details about DNS changes.
|
|
|
|
If you've decided to use the default hostname, you won't need to do any extra DNS configuration.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the [installation](installing.md) command: `just install-all`.
|
|
|
|
### External databases
|
|
|
|
Please note that, if your setup utilizes an external database, you must also establish configuration for the sliding sync proxy. Alter the defaults below to suit your configuration:
|
|
|
|
```yaml
|
|
matrix_sliding_sync_database_username: 'matrix_sliding_sync'
|
|
matrix_sliding_sync_database_password: ''
|
|
matrix_sliding_sync_database_hostname: ''
|
|
matrix_sliding_sync_database_port: 5432
|
|
matrix_sliding_sync_database_name: 'matrix_sliding_sync'
|
|
```
|
|
|
|
## Usage
|
|
|
|
You **don't need to do anything special** to make use of the Sliding Sync proxy. Simply open your client which supports Sliding Sync (like Element X) and log in.
|
|
|
|
When the Sliding Sync proxy is [installed](#installing), your `/.well-known/matrix/client` file is also updated. A new `org.matrix.msc3575.proxy` section and `url` property are added there and made to point to your Sliding Sync proxy's base URL (e.g. `https://matrix.example.com/sliding-sync`).
|
|
|
|
This allows clients which support Sliding Sync to detect the Sliding Sync proxy's URL and make use of it.
