Edit descriptions about installation of components (#3842)
* Replace installation command shortcut for the "just" program with the most conservative raw ansible-playbook command

This commit replaces installation command shortcut ("recipe") for the "just" program with the raw ansible-playbook command, so that the shortcut will be added to it later. The command is so conservative that failure of the command will mean something is clearly broken.

* Add description about shortcut command with the "just" program to the ansible-playbook command with "setup-all" and "start" tags

It also explains difference between "just install-all" and "just setup-all" recipes. The explanation is based on docs/playbook-tags.md

* Update raw ansible-playbook command to have it do what "just install-all" or "just setup-all" does

Since "just install-all" or "just setup-all" invokes "ensure-matrix-users-created" as well, it needs adding to the raw ansible-playbook command.

* Remove "ensure-matrix-users-created" from the raw ansible-playbook command which does not need it

Also: update the "just" recipes accordingly. "just install-all" and "just setup-all" run "ensure-matrix-users-created" tag as well, therefore they need to be replaced with "run-tags" recipes to skip "ensure-matrix-users-created"

* Update docs/configuring-playbook-etherpad.md: add ensure-matrix-users-created to the raw ansible-playbook

* Add description about "ensure-matrix-users-created" and create a list with description about shortcut commands with "just"

This commit also fixes list item capitalization and punctuation.

* Replace "run the installation command" with "run the playbook with tags"

Now that shortcut commands for the "just" program are displayed along with the existing "installation command", this commit replaces "run the installation command" with "run the playbook with tags" in order to prevent misunderstanding and confusion.

Setting up Mautrix Signal bridging (optional)

The playbook can install and configure mautrix-signal for you.

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

Note: This revamped version of the mautrix-signal (legacy) may increase the CPU usage of your homeserver.

Prerequisites (optional)

Prepare Postgres database on external Postgres server

If you're running with the Postgres database server integrated by the playbook (which is the default), you don't need to do anything special and can easily proceed with installing.

However, if you're using an external Postgres server, you'd need to manually prepare a Postgres database for this bridge and adjust the variables related to that (matrix_mautrix_signal_database_*).

Enable Appservice Double Puppet

If you want to set up Double Puppeting (hint: you most likely do) for this bridge automatically, you need to have enabled Appservice Double Puppet service for this playbook.

For details about configuring Double Puppeting for this bridge, see the section below: Set up Double Puppeting

Adjusting the playbook configuration

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

matrix_mautrix_signal_enabled: true

There are some additional things you may wish to configure about the bridge before you continue.

By default, any user on your homeserver will be able to use the bridge.

Different levels of permission can be granted to users:

  • relay - Allowed to be relayed through the bridge, no access to commands;
  • user - Use the bridge with puppeting;
  • admin - Use and administer the bridge.

The permissions are following the sequence: nothing < relay < user < admin.

The default permissions are set as follows:

permissions:
  '*': relay
  example.com: user

If you want to augment the preset permissions, you might want to set the additional permissions with the following settings in your vars.yml file:

matrix_mautrix_signal_configuration_extension_yaml: |
  bridge:
    permissions:
      '@YOUR_USERNAME:example.com': admin  

This will add the admin permission to the specific user, while keeping the default permissions.

In case you want to replace the default permissions settings completely, populate the following item within your vars.yml file:

matrix_mautrix_signal_bridge_permissions:
  '@ADMIN:example.com': admin
  '@USER:example.com' : user

You may wish to look at roles/custom/matrix-bridge-mautrix-signal/templates/config.yaml.j2 to find more information on the permissions settings and other options 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 just program are also available: just install-all or just setup-all

    just install-all is useful for maintaining your setup quickly 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. For more information about just shortcuts, take a look at this page: Running just commands

Usage

You then need to start a chat with @signalbot:example.com (where example.com is your base domain, not the matrix. domain).

💡 Set up Double Puppeting

After successfully enabling bridging, you may wish to set up Double Puppeting (hint: you most likely do).

To set it up, you have 2 ways of going about it.

Method 1: automatically, by enabling Appservice Double Puppet

The bridge automatically performs Double Puppeting if Appservice Double Puppet service is configured and enabled on the server for this playbook.

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.

Method 2: manually, by asking each user to provide a working access token

When using this method, each user that wishes to enable Double Puppeting needs to follow the following steps:

  • retrieve a Matrix access token for yourself. Refer to the documentation on how to do that.

  • send the access token to the bot. Example: login-matrix MATRIX_ACCESS_TOKEN_HERE

  • make sure you don't log out the Mautrix-Signal device some time in the future, as that would break the Double Puppeting feature
