# Synapse Docker
|
|
|
|
This Docker image will run Synapse as a single process. It does not provide a database
|
|
server or a TURN server, you should run these separately.
|
|
|
|
## Run
|
|
|
|
We do not currently offer a `latest` image, as this has somewhat undefined semantics.
|
|
We instead release only tagged versions so upgrading between releases is entirely
|
|
within your control.
|
|
|
|
### Using docker-compose (easier)
|
|
|
|
This image is designed to run either with an automatically generated configuration
|
|
file or with a custom configuration that requires manual editing.
|
|
|
|
An easy way to make use of this image is via docker-compose. See the
|
|
[contrib/docker](../contrib/docker)
|
|
section of the synapse project for examples.
|
|
|
|
### Without Compose (harder)
|
|
|
|
If you do not wish to use Compose, you may still run this image using plain
|
|
Docker commands. Note that the following is just a guideline and you may need
|
|
to add parameters to the docker run command to account for the network situation
|
|
with your postgres database.
|
|
|
|
```
|
|
docker run \
|
|
-d \
|
|
--name synapse \
|
|
-v ${DATA_PATH}:/data \
|
|
-e SYNAPSE_SERVER_NAME=my.matrix.host \
|
|
-e SYNAPSE_REPORT_STATS=yes \
|
|
docker.io/matrixdotorg/synapse:latest
|
|
```
|
|
|
|
## Volumes
|
|
|
|
The image expects a single volume, located at ``/data``, that will hold:
|
|
|
|
* 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`` coud 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.
|
|
|
|
## Environment
|
|
|
|
Unless you specify a custom path for the configuration file, a very generic
|
|
file will be generated, based on the following environment settings.
|
|
These are a good starting point for setting up your own deployment.
|
|
|
|
Global settings:
|
|
|
|
* ``UID``, the user id Synapse will run as [default 991]
|
|
* ``GID``, the group id Synapse will run as [default 991]
|
|
* ``SYNAPSE_CONFIG_PATH``, path to a custom config file
|
|
|
|
If ``SYNAPSE_CONFIG_PATH`` is set, you should generate a configuration file
|
|
then customize it manually. No other environment variable is required.
|
|
|
|
Otherwise, a dynamic configuration file will be used. The following environment
|
|
variables are available for configuration:
|
|
|
|
* ``SYNAPSE_SERVER_NAME`` (mandatory), the current server public hostname.
|
|
* ``SYNAPSE_REPORT_STATS``, (mandatory, ``yes`` or ``no``), enable anonymous
|
|
statistics reporting back to the Matrix project which helps us to get funding.
|
|
* ``SYNAPSE_NO_TLS``, set this variable to disable TLS in Synapse (use this if
|
|
you run your own TLS-capable reverse proxy).
|
|
* ``SYNAPSE_ENABLE_REGISTRATION``, set this variable to enable registration on
|
|
the Synapse instance.
|
|
* ``SYNAPSE_ALLOW_GUEST``, set this variable to allow guest joining this server.
|
|
* ``SYNAPSE_EVENT_CACHE_SIZE``, the event cache size [default `10K`].
|
|
* ``SYNAPSE_CACHE_FACTOR``, the cache factor [default `0.5`].
|
|
* ``SYNAPSE_RECAPTCHA_PUBLIC_KEY``, set this variable to the recaptcha public
|
|
key in order to enable recaptcha upon registration.
|
|
* ``SYNAPSE_RECAPTCHA_PRIVATE_KEY``, set this variable to the recaptcha private
|
|
key in order to enable recaptcha upon registration.
|
|
* ``SYNAPSE_TURN_URIS``, set this variable to the coma-separated list of TURN
|
|
uris to enable TURN for this homeserver.
|
|
* ``SYNAPSE_TURN_SECRET``, set this to the TURN shared secret if required.
|
|
* ``SYNAPSE_MAX_UPLOAD_SIZE``, set this variable to change the max upload size [default `10M`].
|
|
|
|
Shared secrets, that will be initialized to random values if not set:
|
|
|
|
* ``SYNAPSE_REGISTRATION_SHARED_SECRET``, secret for registrering users if
|
|
registration is disable.
|
|
* ``SYNAPSE_MACAROON_SECRET_KEY`` secret for signing access tokens
|
|
to the server.
|
|
|
|
Database specific values (will use SQLite if not set):
|
|
|
|
* `POSTGRES_DB` - The database name for the synapse postgres database. [default: `synapse`]
|
|
* `POSTGRES_HOST` - The host of the postgres database if you wish to use postgresql instead of sqlite3. [default: `db` which is useful when using a container on the same docker network in a compose file where the postgres service is called `db`]
|
|
* `POSTGRES_PASSWORD` - The password for the synapse postgres database. **If this is set then postgres will be used instead of sqlite3.** [default: none] **NOTE**: You are highly encouraged to use postgresql! Please use the compose file to make it easier to deploy.
|
|
* `POSTGRES_USER` - The user for the synapse postgres database. [default: `matrix`]
|
|
|
|
Mail server specific values (will not send emails if not set):
|
|
|
|
* ``SYNAPSE_SMTP_HOST``, hostname to the mail server.
|
|
* ``SYNAPSE_SMTP_PORT``, TCP port for accessing the mail server [default ``25``].
|
|
* ``SYNAPSE_SMTP_USER``, username for authenticating against the mail server if any.
|
|
* ``SYNAPSE_SMTP_PASSWORD``, password for authenticating against the mail server if any.
|
|
|
|
## Build
|
|
|
|
Build the docker image with the `docker build` command from the root of the synapse repository.
|
|
|
|
```
|
|
docker build -t docker.io/matrixdotorg/synapse . -f docker/Dockerfile
|
|
```
|
|
|
|
The `-t` option sets the image tag. Official images are tagged `matrixdotorg/synapse:<version>` where `<version>` is the same as the release tag in the synapse git repository.
|
|
|
|
You may have a local Python wheel cache available, in which case copy the relevant
|
|
packages in the ``cache/`` directory at the root of the project.
