Setting up a Generic Mautrix Bridge (optional)

The playbook can install and configure various mautrix bridges (twitter, facebook, instagram, signal, hangouts, googlechat, etc.), as well as many other (non-mautrix) bridges. This is a common guide for configuring mautrix bridges.

You can see each bridge's features at in the ROADMAP.md file in its corresponding mautrix repository.

Adjusting the playbook configuration

To enable the bridge, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

# Replace SERVICENAME with one of: twitter, facebook, instagram, ..
matrix_mautrix_SERVICENAME_enabled: true

There are some additional things you may wish to configure about the bridge before you continue. Each bridge may have additional requirements besides _enabled: true. For example, the mautrix-telegram bridge (our documentation page about it is here) requires the matrix_mautrix_telegram_api_id and matrix_mautrix_telegram_api_hash variables to be defined. Refer to each bridge's individual documentation page for details about enabling bridges.

To configure a user as an administrator for all bridges, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

matrix_admin: "@alice:{{ matrix_domain }}"

Alternatively (more verbose, but allows multiple admins to be configured), you can do the same on a per-bridge basis with:

matrix_mautrix_SERVICENAME_configuration_extension_yaml: |
  bridge:
    permissions:
      '@alice:{{ matrix_domain }}': admin  

encryption

Encryption support is off by default. If you would like to enable encryption, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

for all bridges with encryption support:

matrix_bridges_encryption_enabled: true
matrix_bridges_encryption_default: true

Alternatively, for a specific bridge:

matrix_mautrix_SERVICENAME_bridge_encryption_enabled: true
matrix_mautrix_SERVICENAME_bridge_encryption_default: true

relay mode

Relay mode is off by default. If you would like to enable relay mode, add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file:

for all bridges with relay mode support:

matrix_bridges_relay_enabled: true

Alternatively, for a specific bridge:

matrix_mautrix_SERVICENAME_configuration_extension_yaml: |
  bridge:
    relay:
      enabled: true  

You can only have one matrix_mautrix_SERVICENAME_configuration_extension_yaml definition in vars.yml per bridge, so if you need multiple pieces of configuration there, just merge them like this:

matrix_mautrix_SERVICENAME_configuration_extension_yaml: |
  bridge:
    permissions:
      '@alice:{{ matrix_domain }}': admin
    encryption:
      allow: true
      default: true  

Setting the bot's username

matrix_mautrix_SERVICENAME_appservice_bot_username: "BOTNAME"

Can be used to set the username for the bridge.

Discovering additional configuration options

You may wish to look at roles/custom/matrix-bridge-mautrix-SERVICENAME/templates/config.yaml.j2 and roles/custom/matrix-bridge-mautrix-SERVICENAME/defaults/main.yml to find other things you would like to configure.

Installing

After configuring the playbook, run it with playbook tags as below:

ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,ensure-matrix-users-created,start

Notes:

• The ensure-matrix-users-created playbook tag makes the playbook automatically create the bot's user account.

• The shortcut commands with the just program are also available: just install-all or just setup-all

  just install-all is useful for maintaining your setup quickly (2x-5x faster than just setup-all) when its components remain unchanged. If you adjust your vars.yml to remove other components, you'd need to run just setup-all, or these components will still remain installed.

Set up Double Puppeting

To set up Double Puppeting enable the Appservice Double Puppet service for this playbook.

The bridge automatically performs Double Puppeting if Shared Secret Auth is configured and enabled on the server for this playbook by adding

matrix_appservice_double_puppet_enabled: true

This is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.

Controlling the logging level

matrix_mautrix_SERVICENAME_logging_level: WARN

to vars.yml to control the logging level, where you may replace WARN with one of the following to control the verbosity of the logs generated: TRACE, DEBUG, INFO, WARN, ERROR, or FATAL.

If you have issues with a service, and are requesting support, the higher levels of logging will generally be more helpful.

Usage

To use the bridge, you need to start a chat with @SERVICENAMEbot:example.com (where example.com is your base domain, not the matrix. domain).

Send login to the bridge bot to get started. You can learn more here about authentication from the bridge's official documentation on Authentication: https://docs.mau.fi/bridges/python/SERVICENAME/authentication.html

If you run into trouble, check the Troubleshooting section below.

Troubleshooting

For troubleshooting information with a specific bridge, please see the playbook documentation about it (some other document in in docs/) and the upstream (mautrix) bridge documentation for that specific bridge.

Reporting bridge bugs should happen upstream, in the corresponding mautrix repository, not to us.
