Lots of people seem to get confused by this mode, and it's been deprecated since Synapse 1.1.0. It's time for it to go.

# Synapse Docker
|
|
|
|
This Docker image will run Synapse as a single process. By default it uses a
|
|
sqlite database; for production use you should connect it to a separate
|
|
postgres database.
|
|
|
|
The image also does *not* provide a TURN server.
|
|
|
|
## Volumes
|
|
|
|
By default, the image expects a single volume, located at ``/data``, that will hold:
|
|
|
|
* configuration files;
|
|
* temporary files during uploads;
|
|
* uploaded media and thumbnails;
|
|
* the SQLite database if you do not configure postgres;
|
|
* the appservices configuration.
|
|
|
|
You are free to use separate volumes depending on storage endpoints at your
|
|
disposal. For instance, ``/data/media`` could be stored on a large but low
|
|
performance hdd storage while other files could be stored on high performance
|
|
endpoints.
|
|
|
|
In order to setup an application service, simply create an ``appservices``
|
|
directory in the data volume and write the application service Yaml
|
|
configuration file there. Multiple application services are supported.
|
|
|
|
## Generating a configuration file
|
|
|
|
The first step is to generate a valid config file. To do this, you can run the
|
|
image with the `generate` command line option.
|
|
|
|
You will need to specify values for the `SYNAPSE_SERVER_NAME` and
|
|
`SYNAPSE_REPORT_STATS` environment variable, and mount a docker volume to store
|
|
the configuration on. For example:
|
|
|
|
```
|
|
docker run -it --rm \
|
|
--mount type=volume,src=synapse-data,dst=/data \
|
|
-e SYNAPSE_SERVER_NAME=my.matrix.host \
|
|
-e SYNAPSE_REPORT_STATS=yes \
|
|
matrixdotorg/synapse:latest generate
|
|
```
|
|
|
|
For information on picking a suitable server name, see
|
|
https://github.com/matrix-org/synapse/blob/master/INSTALL.md.
|
|
|
|
The above command will generate a `homeserver.yaml` in (typically)
|
|
`/var/lib/docker/volumes/synapse-data/_data`. You should check this file, and
|
|
customise it to your needs.
|
|
|
|
The following environment variables are supported in `generate` mode:
|
|
|
|
* `SYNAPSE_SERVER_NAME` (mandatory): the server public hostname.
|
|
* `SYNAPSE_REPORT_STATS` (mandatory, `yes` or `no`): whether to enable
|
|
anonymous statistics reporting.
|
|
* `SYNAPSE_CONFIG_DIR`: where additional config files (such as the log config
|
|
and event signing key) will be stored. Defaults to `/data`.
|
|
* `SYNAPSE_CONFIG_PATH`: path to the file to be generated. Defaults to
|
|
`<SYNAPSE_CONFIG_DIR>/homeserver.yaml`.
|
|
* `SYNAPSE_DATA_DIR`: where the generated config will put persistent data
|
|
such as the database and media store. Defaults to `/data`.
|
|
* `UID`, `GID`: the user id and group id to use for creating the data
|
|
directories. Defaults to `991`, `991`.
|
|
|
|
## Running synapse
|
|
|
|
Once you have a valid configuration file, you can start synapse as follows:
|
|
|
|
```
|
|
docker run -d --name synapse \
|
|
--mount type=volume,src=synapse-data,dst=/data \
|
|
-p 8008:8008 \
|
|
matrixdotorg/synapse:latest
|
|
```
|
|
|
|
You can then check that it has started correctly with:
|
|
|
|
```
|
|
docker logs synapse
|
|
```
|
|
|
|
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:
|
|
|
|
* `SYNAPSE_CONFIG_DIR`: where additional config files are stored. Defaults to
|
|
`/data`.
|
|
* `SYNAPSE_CONFIG_PATH`: path to the config file. Defaults to
|
|
`<SYNAPSE_CONFIG_DIR>/homeserver.yaml`.
|
|
* `SYNAPSE_WORKER`: module to execute, used when running synapse with workers.
|
|
Defaults to `synapse.app.homeserver`, which is suitable for non-worker mode.
|
|
* `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`.
|
|
|
|
## TLS support
|
|
|
|
The default configuration exposes a single HTTP port: http://localhost:8008. It
|
|
is suitable for local testing, but for any practical use, you will either need
|
|
to use a reverse proxy, or configure Synapse to expose an HTTPS port.
|
|
|
|
For documentation on using a reverse proxy, see
|
|
https://github.com/matrix-org/synapse/blob/master/docs/reverse_proxy.md.
|
|
|
|
For more information on enabling TLS support in synapse itself, see
|
|
https://github.com/matrix-org/synapse/blob/master/INSTALL.md#tls-certificates. Of
|
|
course, you will need to expose the TLS port from the container with a `-p`
|
|
argument to `docker run`.
|
|
|
|
## Legacy dynamic configuration file support
|
|
|
|
The docker image used to support creating a dynamic configuration file based
|
|
on environment variables. This is no longer supported, and an error will be
|
|
raised if you try to run synapse without a config file.
|
|
|
|
It is, however, possible to generate a static configuration file based on
|
|
the environment variables that were previously used. To do this, run the docker
|
|
container once with the environment variables set, and `migrate_config`
|
|
command line option. For example:
|
|
|
|
```
|
|
docker run -it --rm \
|
|
--mount type=volume,src=synapse-data,dst=/data \
|
|
-e SYNAPSE_SERVER_NAME=my.matrix.host \
|
|
-e SYNAPSE_REPORT_STATS=yes \
|
|
matrixdotorg/synapse:latest migrate_config
|
|
```
|
|
|
|
This will generate the same configuration file as the legacy mode used, and
|
|
will store it in `/data/homeserver.yaml`. You can then use it as shown above at
|
|
[Running synapse](#running-synapse).
|
|
|
|
Note that the defaults used in this configuration file may be different to
|
|
those when generating a new config file with `generate`: for example, TLS is
|
|
enabled by default in this mode. You are encouraged to inspect the generated
|
|
configuration file and edit it to ensure it meets your needs.
|
|
|
|
## Building the image
|
|
|
|
If you need to build the image from a Synapse checkout, use the following `docker
|
|
build` command from the repo's root:
|
|
|
|
```
|
|
docker build -t matrixdotorg/synapse -f docker/Dockerfile .
|
|
```
|
|
|
|
You can choose to build a different docker image by changing the value of the `-f` flag to
|
|
point to another Dockerfile.
