Setting up matrix-registration-bot (optional)

The playbook can install and configure matrix-registration-bot for you.

The bot allows you to easily create and manage registration tokens. It can be used for an invitation-based server, where you invite someone by sending them a registration token. They can register as normal but have to provide a valid registration token in a final step of the registration.

See the project's documentation to learn what it does and why it might be useful to you.

Registering the bot user

By default, the playbook will set use the bot with a username like this: @bot.matrix-registration-bot:DOMAIN.

(to use a different username, adjust the matrix_bot_matrix_registration_bot_matrix_user_id_localpart variable).

You need to register the bot user manually before setting up the bot. You can use the playbook to register a new user:

ansible-playbook -i inventory/hosts setup.yml --extra-vars='username=bot.matrix-registration-bot password=PASSWORD_FOR_THE_BOT admin=yes' --tags=register-user

Choose a strong password for the bot. You can generate a good password with a command like this: pwgen -s 64 1.

Obtaining an admin access token

In order to use the bot you need to add an admin user's access token token to the configuration. Refer to the documentation on how to obtain an access token.

Adjusting the playbook configuration

Add the following configuration to your inventory/host_vars/matrix.DOMAIN/vars.yml file:

matrix_bot_matrix_registration_bot_enabled: true
# Token obtained via logging into the bot account (see above)
matrix_bot_matrix_registration_bot_bot_access_token: "syt_bW9hbm9z_XXXXXXXXXXXXXr_2kuzbE"

# Enables registration
matrix_synapse_enable_registration: true

# Restrict registration to users with a token
matrix_synapse_registration_requires_token: true

Installing

After configuring the playbook, run the installation command again:

ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start

Usage

To use the bot, create a non-encrypted room and invite @bot.matrix-registration-bot:DOMAIN (where DOMAIN is your base domain, not the matrix. domain).

In this room send help and the bot will reply with all options.

You can also refer to the upstream Usage documentation. If you have any questions, or if you need help setting it up, read the troublshooting guide or join #matrix-registration-bot:hyteck.de.
