|
||||
- Manage DNS records via the v2 REST API of the DNS Made Easy service. Records only; no manipulation of domains or monitor/account support yet. See: http://www.dnsmadeeasy.com/services/rest-api/

- Domain to work with. Can be the domain name (e.g. "mydomain.com") or the numeric ID of the domain in DNS Made Easy (e.g. "839989") for faster resolution.
|
||||
required: true
|
||||
default: null
|
||||
|
||||
record_name:
|
||||
description:
|
||||
- Record name (to get/create/delete/update).
|
||||
If record_name is not specified; all records for the domain will be returned as "result" regardless of state argument.

|
||||
record_type:
|
||||
description:
|

- Record value. HTTPRED: <redirection URL>, MX: <priority> <target name>, NS: <name server>, PTR: <target name>, SRV: <priority> <weight> <port> <target name>, TXT: <text value>
|
||||
If record_value is not specified; no changes will be made and the record will be returned as "result" (e.g. can be used to fetch a record's current id, type, and ttl)

|
||||
state:
|
||||
description:
|

- If state is "present", record will be created. If state is "present" and if record exists and values have changed, it will be updated.
|
||||
If state is absent, record will be removed.
|
||||
required: true
|
||||
choices: [ 'present', 'absent' ]
|
||||
default: null
|
||||
|
||||
notes:
|
||||
- The DNS Made Easy service requires that machines interacting with it's API have the proper time + timezone set. Be sure you're within a few seconds of actual GMT by using NTP.
|
||||
- This module returns record(s) as "result" when state == 'present'. It can be be registered and used in your playbooks.
