Local data types are used to get values directly from SàT: - !sat_conf to retrieve a configuration value - !sat_generate_pwd to generate a password - !sat_param for parameters specified a launch Data can be exposed when an instance is launched, this can be used to specify the port (notably the one used for web), or a generated password.
