short_description: Loads and executes an inventory plugin specified in a YAML config
|
|
description:
|
|
- By whitelisting C(auto) as the final inventory plugin, any YAML inventory config file with a
|
|
C(plugin) key at its root will automatically cause the named plugin to be loaded and executed with that
|
|
config. This effectively provides automatic whitelisting of all installed/accessible inventory plugins.
|
|
- To disable this behavior, remove C(auto) from the C(INVENTORY_ENABLED) config element.

EXAMPLES = '''
|
|
# This plugin is not intended for direct use; it is a fallback mechanism for automatic whitelisting of

# all installed inventory plugins.
