## Basic usage

1. Set up Docker Swarm and [`abra`]
2. Deploy [`coop-cloud/traefik`]
3. `abra app new matrix-synapse --secrets` (optionally with `--pass` if you'd like
   to save secrets in `pass`)
4. `abra app YOURAPPDOMAIN config` - be sure to change `$DOMAIN` to something that resolves to
   your Docker swarm box
5. `abra app YOURAPPDOMAIN deploy`
6. Create an initial user:
   `abra app YOURAPPDOMAIN run app register_new_matrix_user -c /data/homeserver.yaml http://localhost:8008`

## Tips & Tricks

### Seeing what changed in `homeserver.yaml` between versions

Change the version range to suit your needs.

```
git clone https://github.com/matrix-org/synapse
cd synapse/docs
git log --follow -p v1.48.0..v1.51.0 sample_config.yaml
```

### Generating a new `homeserver.yaml`

The default is also available to see [here](https://matrix-org.github.io/synapse/latest/usage/configuration/homeserver_sample_config.html).

```
docker run -it \
  --entrypoint="" \
  -e SYNAPSE_SERVER_NAME=foo.com \
  -e SYNAPSE_REPORT_STATS=no \
  matrixdotorg/synapse:v1.48.0 \
  sh -c '/start.py generate; cat /data/homeserver.yaml' > homeserver.yaml.tmpl`
```

### Generating a new `<server>.log.config`

```
docker run -it \
  --entrypoint="" \
  -e SYNAPSE_SERVER_NAME=foo.com \
  -e SYNAPSE_REPORT_STATS=no \
  matrixdotorg/synapse:v1.48.0 \
  sh -c '/start.py generate; cat /data/foo.com.log.config' > log.config
```
