module: nios_zone
version_added: "2.5"
author: "Peter Sprygada (@privateip)"
short_description: Configure Infoblox NIOS DNS zones
description:
  - Adds and/or removes instances of DNS zone objects from
    Infoblox NIOS servers.  This module manages NIOS C(zone_auth) objects
    using the Infoblox WAPI interface over REST.
requirements:
  - infoblox-client
extends_documentation_fragment: nios
options:
  fqdn:
    description:
      - Specifies the qualified domain name to either add or remove from
        the NIOS instance based on the configured C(state) value.
    required: true
    aliases:
      - name
  view:
    description:
      - Configures the DNS view name for the configured resource.  The
        specified DNS zone must already exist on the running NIOS instance
        prior to configuring zones.
    required: true
    default: default
    aliases:
      - dns_view
  grid_primary:
    description:
      - Configures the grid primary servers for this zone.
    suboptions:
      name:
        description:
          - The name of the grid primary server
  grid_secondaries:
    description:
      - Configures the grid secondary servers for this zone.
    suboptions:
      name:
        description:
          - The name of the grid secondary server
  ns_group:
    version_added: "2.6"
    description:
      - Configures the name server group for this zone. Name server group is
        mutually exclusive with grid primary and grid secondaries.
  restart_if_needed:
    version_added: "2.6"
    description:
      - If set to true, causes the NIOS DNS service to restart and load the
        new zone configuration
    type: bool
  zone_format:
    version_added: "2.7"
    description:
      - Create an authorative Reverse-Mapping Zone which is an area of network
        space for which one or more name servers-primary and secondary-have the
        responsibility to respond to address-to-name queries. It supports
        reverse-mapping zones for both IPv4 and IPv6 addresses.
    default: FORWARD
  extattrs:
    description:
      - Allows for the configuration of Extensible Attributes on the
        instance of the object.  This argument accepts a set of key / value
        pairs for configuration.
  comment:
    description:
      - Configures a text string comment to be associated with the instance
        of this object.  The provided text string will be configured on the
        object instance.
  state:
    description:
      - Configures the intended state of the instance of the object on
        the NIOS server.  When this value is set to C(present), the object
        is configured on the device and when this value is set to C(absent)
        the value is removed (if necessary) from the device.
    default: present
    choices:
      - present
      - absent
