module: digital_ocean_domain
short_description: Create/delete a DNS domain in DigitalOcean
description:
     - Create/delete a DNS domain in DigitalOcean.
author: "Michael Gregson (@mgregson)"
options:
  state:
    description:
     - Indicate desired state of the target.
    default: present
    choices: ['present', 'absent']
  id:
    description:
     - Numeric, the droplet id you want to operate on.
    aliases: ['droplet_id']
  name:
    description:
     - String, this is the name of the droplet - must be formatted by hostname rules, or the name of a SSH key, or the name of a domain.
  ip:
    description:
     - An 'A' record for '@' ($ORIGIN) will be created with the value 'ip'.  'ip' is an IP version 4 address.
extends_documentation_fragment:
- community.general.digital_ocean.documentation

notes:
  - Environment variables DO_OAUTH_TOKEN can be used for the oauth_token.
  - As of Ansible 1.9.5 and 2.0, Version 2 of the DigitalOcean API is used, this removes C(client_id) and C(api_key) options in favor of C(oauth_token).
  - If you are running Ansible 1.9.4 or earlier you might not be able to use the included version of this module as the API version used has been retired.

requirements:
  - "python >= 2.6"
