Configuring Synapse (optional)

By default, this playbook configures the Synapse Matrix server, so that it works for the general case. If that's enough for you, you can skip this document.

The playbook provides lots of customization variables you could use to change Synapse's settings.

Their defaults are defined in roles/matrix-synapse/defaults/main.yml and they ultimately end up in the generated /matrix/synapse/config/homeserver.yaml file (on the server). This file is generated from the roles/matrix-synapse/templates/synapse/homeserver.yaml.j2 template.

If there's an existing variable which controls a setting you wish to change, you can simply define that variable in your configuration file (inventory/host_vars/matrix.<your-domain>/vars.yml) and re-run the playbook to apply the changes.

Alternatively, if there is no pre-defined variable for a Synapse setting you wish to change:

• you can either request a variable to be created (or you can submit such a contribution yourself). Keep in mind that it's probably not a good idea to create variables for each one of Synapse's various settings that rarely get used.

• or, you can extend and override the default configuration (homeserver.yaml.j2) by making use of the matrix_synapse_configuration_extension_yaml variable. You can find information about this in roles/matrix-synapse/defaults/main.yml.

• or, if extending the configuration is still not powerful enough for your needs, you can override the configuration completely using matrix_synapse_configuration (or matrix_synapse_configuration_yaml). You can find information about this in roles/matrix-synapse/defaults/main.yml.

Synapse Admin

Certain Synapse administration tasks (managing users and rooms, etc.) can be performed via a web user-interace, if you install Synapse Admin.
