module: rax_dns_record
short_description: Manage DNS records on Rackspace Cloud DNS
description:
- Manage DNS records on Rackspace Cloud DNS
version_added: 1.5
options:
comment:
description:
- Brief description of the domain. Maximum length of 160 characters
data:
description:
- IP address for A/AAAA record, FQDN for CNAME/MX/NS, or text data for
SRV/TXT
required: True
domain:
description:
- Domain name to create the record in. This is an invalid option when
type=PTR
loadbalancer:
description:
- Load Balancer ID to create a PTR record for. Only used with type=PTR
version_added: 1.7
name:
description:
- FQDN record name to create
required: True
priority:
description:
- Required for MX and SRV records, but forbidden for other record types.
If specified, must be an integer from 0 to 65535.
server:
description:
- Server ID to create a PTR record for. Only used with type=PTR
version_added: 1.7
state:
description:
- Indicate desired state of the resource
choices:
- present
- absent
default: present
ttl:
description:
- Time to live of record in seconds
default: 3600
type:
description:
- DNS record type
choices:
- A
- AAAA
- CNAME
- MX
- NS
- SRV
- TXT
- PTR
required: true
notes:
- "It is recommended that plays utilizing this module be run with
C(serial: 1) to avoid exceeding the API request limit imposed by
the Rackspace CloudDNS API"
- To manipulate a C(PTR) record either C(loadbalancer) or C(server) must be
supplied
- As of version 1.7, the C(type) field is required and no longer defaults to an C(A) record.
- C(PTR) record support was added in version 1.7
