module: hwc_vpc_private_ip
description:
    - vpc private ip management.
short_description: Creates a resource of Vpc/PrivateIP in Huawei Cloud
notes:
    - If O(id) option is provided, it takes precedence over O(subnet_id), O(ip_address) for private ip selection.
    - O(subnet_id), O(ip_address) are used for private ip selection. If more than one private ip with this options exists, execution is aborted.
    - No parameter support updating. If one of option is changed, the module will create a new resource.
version_added: '0.2.0'
author: Huawei Inc. (@huaweicloud)
requirements:
    - keystoneauth1 >= 3.6.0
