module: dnsmadeeasy
version_added: "1.3"
short_description: Interface with dnsmadeeasy.com (a DNS hosting service).
description:
- "Manages DNS records via the v2 REST API of the DNS Made Easy service. It handles records only; there is no manipulation of domains or monitor/account support yet. See: U(http://www.dnsmadeeasy.com/services/rest-api/)"
options:
account_key:
description:
- Accout API Key.
required: true
default: null
account_secret:
description:
- Accout Secret Key.
required: true
default: null
domain:
description:
- 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 in "result" regardless of the state argument.
required: false
default: null
record_type:
description:
- Record type.
required: false
choices: [ 'A', 'AAAA', 'CNAME', 'HTTPRED', 'MX', 'NS', 'PTR', 'SRV', 'TXT' ]
default: null
record_value:
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 in 'result' (in other words, this module can be used to fetch a record's current id, type, and ttl)"
required: false
default: null
record_ttl:
description:
- record's "Time to live". Number of seconds the record remains cached in DNS servers.
required: false
default: 1800
state:
description:
- whether the record should exist or not
required: true
choices: [ 'present', 'absent' ]
default: null
notes:
- The DNS Made Easy service requires that machines interacting with the API have the proper time and timezone set. Be sure you are within a few seconds of actual time by using NTP.
- This module returns record(s) in the "result" element when 'state' is set to 'present'. This value can be be registered and used in your playbooks.
requirements: [ urllib, urllib2, hashlib, hmac ]
