prosody/files/prosody.cfg.lua

+-- Prosody Example Configuration File
+--
+-- Information on configuring Prosody can be found on our
+-- website at http://prosody.im/doc/configure
+--
+-- Tip: You can check that the syntax of this file is correct
+-- when you have finished by running: luac -p prosody.cfg.lua
+-- If there are any errors, it will let you know what and where
+-- they are, otherwise it will keep quiet.
+--
+-- The only thing left to do is rename this file to remove the .dist ending, and fill in the
+-- blanks. Good luck, and happy Jabbering!
+
+
+
+
+------ Additional config files ------
+-- For organizational purposes you may prefer to add VirtualHost and
+-- Component definitions in their own config files. This line includes
+-- all config files in /etc/prosody/conf.d/
+
+Include "conf.d/*.cfg.lua"

+---------- Server-wide settings ----------
+-- Settings in this section apply to the whole server and are the default settings
+-- for any virtual hosts
+
+-- This is a (by default, empty) list of accounts that are admins
+-- for the server. Note that you must create the accounts separately
+-- (see http://prosody.im/doc/creating_accounts for info)
+-- Example: admins = { "user1@example.com", "user2@example.net" }
+admins = { {{ prosody_admin_accounts | join(",") }} }
+

+-- For more information see: http://prosody.im/doc/libevent

+
+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see http://prosody.im/doc/components
+

+{% for component in prosody_components %}

+{% endfor %}
+{% endif %}
+-- Set up a SOCKS5 bytestream proxy for server-proxied file transfers:
+--Component "proxy.example.com" "proxy65"
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info
+-- see: http://prosody.im/doc/components#adding_an_external_component
+--
+--Component "gateway.example.com"
