## Run
### 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](https://github.com/matrix-org/synapse/tree/master/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 \
--mount type=volume,src=synapse-data,dst=/data \
-e SYNAPSE_SERVER_NAME=my.matrix.host \
-e SYNAPSE_REPORT_STATS=yes \
-p 8448:8448 \
matrixdotorg/synapse:latest
```
## Volumes
The image expects a single volume, located at ``/data``, that will hold:
By default, the image expects a single volume, located at ``/data``, that will hold:

directory in the data volume and write the application service Yaml
configuration file there. Multiple application services are supported.
## TLS certificates
## Generating a configuration file
Synapse requires a valid TLS certificate. You can do one of the following:
The first step is to genearte a valid config file. To do this, you can run the
image with the `generate` commandline option.
* Provide your own certificate and key (as
`${DATA_PATH}/${SYNAPSE_SERVER_NAME}.tls.crt` and
`${DATA_PATH}/${SYNAPSE_SERVER_NAME}.tls.key`, or elsewhere by providing an
entire config as `${SYNAPSE_CONFIG_PATH}`). In this case, you should forward
traffic to port 8448 in the container, for example with `-p 443:8448`.
* Use a reverse proxy to terminate incoming TLS, and forward the plain http
traffic to port 8008 in the container. In this case you should set `-e
SYNAPSE_NO_TLS=1`.
* Use the ACME (Let's Encrypt) support built into Synapse. This requires
`${SYNAPSE_SERVER_NAME}` port 80 to be forwarded to port 8009 in the
container, for example with `-p 80:8009`. To enable it in the docker
container, set `-e SYNAPSE_ACME=1`.
If you don't do any of these, Synapse will fail to start with an error similar to:
synapse.config._base.ConfigError: Error accessing file '/data/<server_name>.tls.crt' (config for tls_certificate): No such file or directory
## 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: see [Generating a config
file](#generating-a-config-file).
Otherwise, a dynamic configuration file will be used.
### Environment variables used to build a dynamic configuration file
The following environment variables are used to build the configuration file
when ``SYNAPSE_CONFIG_PATH`` is not set.
* ``SYNAPSE_SERVER_NAME`` (mandatory), the 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`, (accepts `true`, `false`, `on`, `off`, `1`, `0`, `yes`, `no`]): disable
TLS in Synapse (use this if you run your own TLS-capable reverse proxy). Defaults
to `false` (ie, TLS is enabled by default).
* ``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_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`].
* ``SYNAPSE_ACME``: set this to enable the ACME certificate renewal support.
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:
`synapse`]
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.
### Generating a config file
It is possible to generate a basic configuration file for use with
`SYNAPSE_CONFIG_PATH` using the `generate` commandline option. You will need to
specify values for `SYNAPSE_CONFIG_PATH`, `SYNAPSE_SERVER_NAME` and
`SYNAPSE_REPORT_STATS`, and mount a docker volume to store the data on. For
example:
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_CONFIG_PATH=/data/homeserver.yaml \
-e SYNAPSE_SERVER_NAME=my.matrix.host \
-e SYNAPSE_REPORT_STATS=yes \
matrixdotorg/synapse:latest generate
```
This will generate a `homeserver.yaml` in (typically)
`/var/lib/docker/volumes/synapse-data/_data`, which you can then customise and
use with:
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 datatase 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 \
-e SYNAPSE_CONFIG_PATH=/data/homeserver.yaml \
-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`.
* `UID`, `GID`: the user and group id to run Synapse as. Defaults to `991`, `991`.
## 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.rst.
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
For backwards-compatibility only, the docker image supports creating a dynamic
configuration file based on environment variables. This is now deprecated, but
is enabled when the `SYNAPSE_SERVER_NAME` variable is set (and `generate` is
not given).
To migrate from a dynamic configuration file to a static one, run the docker
container once with the environment variables set, and `migrate_config`
commandline 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, but
will store it in `/data/homeserver.yaml` instead of a temporary location. You
can then use it as shown above at [Running synapse](#running-synapse).
