module: ovirt_external_provider_facts
short_description: Retrieve information about one or more oVirt/RHV external providers
author: "Ondra Machacek (@machacekondra)"
deprecated:
    removed_in: 3.0.0  # was Ansible 2.13
    why: When migrating to collection we decided to use only _info modules.
    alternative: Use M(ovirt.ovirt.ovirt_external_provider_info) instead.
description:
    - "Retrieve information about one or more oVirt/RHV external providers."
notes:
    - "This module returns a variable C(ovirt_external_providers), which
       contains a list of external_providers. You need to register the result with
       the I(register) keyword to use it."
options:
    type:
        description:
            - "Type of the external provider."
        choices: ['os_image', 'os_network', 'os_volume', 'foreman']
        required: true
        type: str
    name:
        description:
            - "Name of the external provider, can be used as glob expression."
        type: str
extends_documentation_fragment:
- community.general.ovirt_facts

'''

EXAMPLES = '''
# Examples don't contain auth parameter for simplicity,
# look at ovirt_auth module to see how to reuse authentication:

- name: Gather information about all image external providers named glance
  ovirt_external_provider_info:
    type: os_image
    name: glance
  register: result

- name: Print gathered information
  ansible.builtin.debug:
