Official images are tagged `matrix-org/synapse:` where `` is the same as the release tag in the synapse git repository. + +## Configure + +Synapse provides a command for generating homeserver configuration files. These are a good starting point for setting up your own deployment. + +The documentation below will refer to a `CONFIG_PATH` shell variable. This is a path to a directory where synapse configuration will be stored. It needs to be mapped into the container as a volume at `/synapse/config/` as can be seen in the example `docker run` command. + +Docker container environment variables: +* `GENERATE_CONFIG` - Set this to any non-empty string, such as `yes`, to trigger generation of configuration files. Existing files in the `CONFIG_PATH` will **not** be overwritten. +* `POSTGRES_DATABASE` - 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: `postgres` which is useful when using a container on the same docker network in a compose file where the postgres service is called `postgres`] **NOTE**: `localhost` and `127.0.0.1` refer to the container itself unless running the container with `host` networking. +* `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: `postgres`] +* `REPORT_STATS` - Whether to send anonymous usage statistics back to the Matrix project which helps us to get funding! Must be `yes` or `no`. [default: `yes`] +* `SERVER_NAME` - The domain used for the Matrix homeserver. If you intend to run this synapse instance on a public domain, use that domain.

As it is so easy to use postgresql, when using Docker containers, this is not documented to somewhat discourage it. Choose a `POSTGRES_PASSWORD` instead. + +### Docker Compose + +A `docker-compose.yaml` file is included to ease deployment of the basic synapse and postgres setup. Remember to set a `POSTGRES_PASSWORD` when generating your configuration above.
