It does not provide a +database server or a TURN server, you should run these separately. + +If you run a Postgres server, you should simply include it in the same Compose +project or set the proper environment variables and the image will automatically +use that server. + +## Build + +Build the docker image with the `docker build` command from the root of the synapse repository. + +``` +docker build -t docker.io/matrixdotorg/synapse . +``` + +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. + +## Run + +This image is designed to run either with an automatically generated configuration +file or with a custom configuration that requires manual edition. + +### Automated configuration + +It is recommended that you use Docker Compose to run your containers, including +this image and a Postgres server. A sample ``docker-compose.yml`` is provided, +including example labels for reverse proxying and other artifacts. + +Read the section about environment variables and set at least mandatory variables, +then run the server: + +``` +docker-compose up -d +``` + +If secrets are not specified in the environment variables, they will be generated +as part of the startup. Please ensure these secrets are kept between launches of the +Docker container, as their loss may require users to log in again. + +### Manual configuration + +A sample ``docker-compose.yml`` is provided, including example labels for +reverse proxying and other artifacts. The docker-compose file is an example, +please comment/uncomment sections that are not suitable for your usecase. + +Specify a ``SYNAPSE_CONFIG_PATH``, preferably to a persistent path, +to use manual configuration. To generate a fresh ``homeserver.yaml``, simply run: + +``` +docker-compose run --rm -e SYNAPSE_SERVER_NAME=my.matrix.host synapse generate +``` + +Then, customize your configuration and run the server: + +``` +docker-compose up -d +``` + +### Without Compose + +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.
