If all is well, you should now be able to connect to http://localhost:8008 and
see a confirmation message.
The following environment variables are supported in run mode:
The following environment variables are supported in `run` mode:
* `SYNAPSE_CONFIG_DIR`: where additional config files are stored. Defaults to
`/data`.

* `UID`, `GID`: the user and group id to run Synapse as. Defaults to `991`, `991`.
* `TZ`: the [timezone](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) the container will run with. Defaults to `UTC`.
For more complex setups (e.g. for workers) you can also pass your args directly to synapse using `run` mode. For example like this:
```
docker run -d --name synapse \
--mount type=volume,src=synapse-data,dst=/data \
-p 8008:8008 \
matrixdotorg/synapse:latest run \
-m synapse.app.generic_worker \
--config-path=/data/homeserver.yaml \
--config-path=/data/generic_worker.yaml
```
If you do not provide `-m`, the value of the `SYNAPSE_WORKER` environment variable is used. If you do not provide at least one `--config-path` or `-c`, the value of the `SYNAPSE_CONFIG_PATH` environment variable is used instead.
## Generating an (admin) user
After synapse is running, you may wish to create a user via `register_new_matrix_user`.
