ironic.common.trait_based_networking.config_file module

class ironic.common.trait_based_networking.config_file.ConfigFile(filename)

Bases: object

Provides functionality to read TBN configuration files

Basic flow for use goes like:

cf = ConfigFile(“some_tbn_config.yaml”) # File is read(). valid, reasons = cf.validate() if not valid:

# Do something with reasons, like raise an exception and log. return reasons

cf.parse() # If the file is valid, this should parse the config traits = cf.traits() # Get the parsed traits as a list.

parse()

Render contents of configuration file as TBN objects

The result of this method can later be retrieved by calling traits()

read()

Read the YAML YBN configuration file

traits()

Return the parsed traits from the configuration file.

validate()

Check that contents conform to TBN expectations.

Returns:

(valid, reasons): valid is a boolean representing if the

contents passed validation or not, and reasons is a list of strings describing why the contents failed validation if they are not valid.
