module: gcdns_record
short_description: Creates or removes resource records in Google Cloud DNS
description:
- Creates or removes resource records in Google Cloud DNS.
version_added: "2.2"
author: "William Albert (@walbert947)"
requirements:
- "python >= 2.6"
- "apache-libcloud >= 0.19.0"
options:
state:
description:
- Whether the given resource record should or should not be present.
required: false
choices: ["present", "absent"]
default: "present"
record:
description:
- The fully-qualified domain name of the resource record.
required: true
aliases: ['name']
zone:
description:
- The DNS domain name of the zone (e.g., example.com).
- One of either I(zone) or I(zone_id) must be specified as an
option, or the module will fail.
- If both I(zone) and I(zone_id) are specifed, I(zone_id) will be
used.
required: false
zone_id:
description:
- The Google Cloud ID of the zone (e.g., example-com).
- One of either I(zone) or I(zone_id) must be specified as an
option, or the module will fail.
- These usually take the form of domain names with the dots replaced
with dashes. A zone ID will never have any dots in it.
- I(zone_id) can be faster than I(zone) in projects with a large
number of zones.
- If both I(zone) and I(zone_id) are specifed, I(zone_id) will be
used.
required: false
type:
description:
- The type of resource record to add.
required: true
choices: [ 'A', 'AAAA', 'CNAME', 'SRV', 'TXT', 'SOA', 'NS', 'MX', 'SPF', 'PTR' ]
record_data:
description:
- The record_data to use for the resource record.
- I(record_data) must be specified if I(state) is C(present) or
I(overwrite) is C(True), or the module will fail.
- Valid record_data vary based on the record's I(type). In addition,
resource records that contain a DNS domain name in the value
field (e.g., CNAME, PTR, SRV, .etc) MUST include a trailing dot
in the value.
- Individual string record_data for TXT records must be enclosed in
double quotes.
- For resource records that have the same name but different
record_data (e.g., multiple A records), they must be defined as
multiple list entries in a single record.
required: false
aliases: ['value']
ttl:
description:
- The amount of time in seconds that a resource record will remain
cached by a caching resolver.
required: false
default: 300
overwrite:
description:
- Whether an attempt to overwrite an existing record should succeed
or fail. The behavior of this option depends on I(state).
- If I(state) is C(present) and I(overwrite) is C(True), this
module will replace an existing resource record of the same name
with the provided I(record_data). If I(state) is C(present) and
I(overwrite) is C(False), this module will fail if there is an
existing resource record with the same name and type, but
different resource data.
- If I(state) is C(absent) and I(overwrite) is C(True), this
module will remove the given resource record unconditionally.
If I(state) is C(absent) and I(overwrite) is C(False), this
module will fail if the provided record_data do not match exactly
with the existing resource record's record_data.
required: false
choices: [True, False]
default: False
service_account_email:
description:
- The e-mail address for a service account with access to Google
Cloud DNS.
required: false
default: null
pem_file:
description:
- The path to the PEM file associated with the service account
email.
- This option is deprecated and may be removed in a future release.
Use I(credentials_file) instead.
required: false
default: null
credentials_file:
description:
- The path to the JSON file associated with the service account
email.
required: false
default: null
project_id:
description:
- The Google Cloud Platform project ID to use.
required: false
default: null
notes:
- See also M(gcdns_zone).
- This modules's underlying library does not support in-place updates for
DNS resource records. Instead, resource records are quickly deleted and
recreated.
- SOA records are technically supported, but their functionality is limited
to verifying that a zone's existing SOA record matches a pre-determined
value. The SOA record cannot be updated.
- Root NS records cannot be updated.
- NAPTR records are not supported.
