+lib_dyn
+=========
+
+A role containing the dyn_record module for managing DNS records through Dyn's
+API
+
+Requirements
+------------
+
+The module requires the `dyn` python module for interacting with the Dyn API.
+https://github.com/dyninc/dyn-python
+
+Example Playbook
+----------------
+
+To make sure the `dyn_record` module is available for use include the role
+before it is used.
+
+ - hosts: servers
+ roles:
+ - lib_dyn

+short_description: Manage records in the Dyn Managed DNS service.
+description:
+ - "Manages DNS records via the REST API of the Dyn Managed DNS service. It
+ - "handles records only; there is no manipulation of zones or account support"
+ - "yet. See: U(https://help.dyn.com/dns-api-knowledge-base/)"
+options:
+ state:
+ description:
+ -"Whether the record should be c(present) or c(absent). Optionally the"
+ - "state c(list) can be used to return the current value of a record."
+ required: true
+ choices: [ 'present', 'absent', 'list' ]
+ default: present
+
+ customer_name:
+ description:
+ - "The Dyn customer name for your account. If not set the value of the"
+ - "c(DYNECT_CUSTOMER_NAME) environment variable is used."
+ required: false
+ default: nil

+ - "c(DYNECT_USER_NAME) environment variable is used."
+ required: false

+
+ user_password:
+ description:
+ - "The Dyn user's password to log in with. If not set the value of the"
+ - "c(DYNECT_PASSWORD) environment variable is used."
+ required: false

+ required: true
+ default: null
+
+ record_fqdn:
+ description:
+ - "Fully qualified domain name of the record name to get, create, delete,"
+ - "or update."
+ required: true
+ default: null
+
+ record_type:
+ description:
+ - "Record type."
+ required: true
+ choices: [ 'A', 'AAAA', 'CNAME', 'PTR', 'TXT' ]
+ default: null
+
+ record_value:
+ description:
+ - "Record value. If record_value is not specified; no changes will be"
+ - "made and the module will fail"
+ required: false
+ default: null
+
+ record_ttl:
+ description:
+ - 'Record's "Time to live". Number of seconds the record remains cached'
+ - 'in DNS servers or c(0) to use the default TTL for the zone.'
+ required: false
+ default: 0
+
+notes:
+ - The module makes a broad assumption that there will be only one record per "node" (FQDN).
+ - 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.
