# Modules are expected to have the following attributes.
|
|
# 1. A required 'handle' method which takes the following params.
|
|
# a) The name will not be this files name, but instead
|
|
# the name specified in configuration (which is the name
|
|
# which will be used to find this module).
|
|
# b) A configuration object that is the result of the merging
|
|
# of cloud configs configuration with legacy configuration
|
|
# as well as any datasource provided configuration
|
|
# c) A cloud object that can be used to access various
|
|
# datasource and paths for the given distro and data provided
|
|
# by the various datasource instance types.
|
|
# d) A argument list that may or may not be empty to this module.
|
|
# Typically those are from module configuration where the module
|
|
# is defined with some extra configuration that will eventually
|
|
# be translated from yaml into arguments to this module.
|
|
# 2. A optional 'frequency' that defines how often this module should be ran.
|
|
# Typically one of PER_INSTANCE, PER_ALWAYS, PER_ONCE. If not
|
|
# provided PER_INSTANCE will be assumed.
|
|
# See settings.py for these constants.
|
|
# 3. A optional 'distros' array/set/tuple that defines the known distros
|
|
# this module will work with (if not all of them). This is used to write
|
|
# a warning out if a module is being ran on a untested distribution for
|
|
# informational purposes. If non existent all distros are assumed and
|
|
# no warning occurs.
