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 edition. + +An easy way to make use of this image is via docker-compose, see the (https://github.com/matrix-org/synapse/tree/develop/contrib/docker)[contrib] 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. + +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. diff --git a/docker/conf/homeserver.yaml b/docker/conf/homeserver.yaml new file mode 100644 index 0000000000..6bc25bb45f --- /dev/null +++ b/docker/conf/homeserver.yaml @@ -0,0 +1,219 @@ +# vim:ft=yaml + +## TLS ## + +tls_certificate_path: "/data/{{ SYNAPSE_SERVER_NAME }}.tls.crt" +tls_private_key_path: "/data/{{ SYNAPSE_SERVER_NAME }}.tls.key" +tls_dh_params_path: "/data/{{ SYNAPSE_SERVER_NAME }}.tls.dh" +no_tls: {{ "True" if SYNAPSE_NO_TLS else "False" }} +tls_fingerprints: [] + +## Server ## + +server_name: "{{ SYNAPSE_SERVER_NAME }}" +pid_file: /homeserver.pid +web_client: False +soft_file_limit: 0 + +## Ports ## + +listeners: + {% if not SYNAPSE_NO_TLS %} + -
