DOCUMENTATION = '''
---
module: os_ironic_inspect
short_description: Explicitly triggers baremetal node introspection in ironic.
extends_documentation_fragment: openstack
author: "Julia Kreger (@juliakreger)"
version_added: "2.1"
description:
    - Requests Ironic to set a node into inspect state in order to collect metadata regarding the node.
      This command may be out of band or in-band depending on the ironic driver configuration.
      This is only possible on nodes in 'manageable' and 'available' state.
options:
    mac:
      description:
        - unique mac address that is used to attempt to identify the host.
    uuid:
      description:
        - globally unique identifier (UUID) to identify the host.
    name:
      description:
        - unique name identifier to identify the host in Ironic.
    ironic_url:
      description:
        - If noauth mode is utilized, this is required to be set to the endpoint URL for the Ironic API.
          Use with "auth" and "auth_type" settings set to None.
    timeout:
      description:
        - A timeout in seconds to tell the role to wait for the node to complete introspection if wait is set to True.
      default: 1200
    availability_zone:
      description:
        - Ignored. Present for backwards compatibility

requirements: ["openstacksdk"]
