# Setting up Hydrogen (optional)
|
|
|
|
The playbook can install and configure the [Hydrogen](https://github.com/element-hq/hydrogen-web) Matrix web client for you.
|
|
|
|
Hydrogen is a lightweight web client that supports mobile and legacy web browsers. It can be installed alongside or instead of Element Web.
|
|
|
|
## Adjusting DNS records
|
|
|
|
By default, this playbook installs Hydrogen on the `hydrogen.` subdomain (`hydrogen.example.com`) and requires you to create a CNAME record for `hydrogen`, which targets `matrix.example.com`.
|
|
|
|
When setting, replace `example.com` with your own.
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable Hydrogen, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
matrix_client_hydrogen_enabled: true
|
|
```
|
|
|
|
### Adjusting the Hydrogen URL (optional)
|
|
|
|
By tweaking the `matrix_client_hydrogen_hostname` and `matrix_client_hydrogen_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 `vars.yml` file:
|
|
|
|
```yaml
|
|
# Switch to the domain used for Matrix services (`matrix.example.com`),
|
|
# so we won't need to add additional DNS records for Hydrogen.
|
|
matrix_client_hydrogen_hostname: "{{ matrix_server_fqn_matrix }}"
|
|
|
|
# Expose under the /hydrogen subpath
|
|
matrix_client_hydrogen_path_prefix: /hydrogen
|
|
```
|
|
|
|
After changing the domain, **you may need to adjust your DNS** records to point the Hydrogen domain to the Matrix server.
|
|
|
|
If you've decided to reuse the `matrix.` domain, you won't need to do any extra DNS configuration.
|
|
|
|
### Extending the configuration
|
|
|
|
There are some additional things you may wish to configure about the client.
|
|
|
|
Take a look at:
|
|
|
|
- `roles/custom/matrix-client-hydrogen/defaults/main.yml` for some variables that you can customize via your `vars.yml` file
|
|
- `roles/custom/matrix-client-hydrogen/templates/config.json.j2` for the client's default configuration. You can override settings (even those that don't have dedicated playbook variables) using the `matrix_client_hydrogen_configuration_extension_json` variable
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the playbook with [playbook tags](playbook-tags.md) as below:
|
|
|
|
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
|
|
```sh
|
|
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
|
|
```
|
|
|
|
The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
|
|
|
|
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.
|
|
|
|
## Troubleshooting
|
|
|
|
As with all other services, you can find the logs in [systemd-journald](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html) by logging in to the server with SSH and running `journalctl -fu matrix-client-hydrogen`.
