dnsupdate

New in version 0.9.

This module performs dynamic DNS updates as per RFC 2136.

parameter	required	default	choices	comments
a	no			The rdata for the A resource record type (i.e. an IPv4 address)
domain	yes			domain name to update (e.g. www)
zone	yes			name of the authoritative zone (e.g. example.com)
keyalgo	no	hmac-md5	hmac-md5 hmac-sha1 hmac-sha224 hmac-sha256 hmac-sha384 hmac-sha512	TSIG key algorithm
mname	yes			address of the master server to which to send the update to. This module does not currently determine the mname from the zone's SOA record.
aaaa	no			The rdata for the AAAA resource record type (i.e. an IPv6 address)
secret	yes			secret TSIG key blob (base-64 encoded)
keyname	yes			name of the TSIG key required to perform updates
ttl	yes	3600		Time to Live for the RR.
txt	no			The rdata for the TXT resource record type. Space-separated strings are encoded as per DNS rules.
cname	no			The rdata for the CNAME resource record type (e.g. example.com)
rtype	no			The type of DNS resource record to operate on
rdata	no			The rdata for the resource record specified by the rtype option
op	no	add	add delete replace	Operation to perform. add adds the specified RR to the RRset, del deletes the specified RRset and replace replaces the RRset with the RRs. If the operation is delete, the value of the RR is not verified as the whole RRset is deleted from the DNS.

• Example from Ansible Playbooks

local_action: dnsupdate keyname="mykey1"
           secret="xxxxxxxxxx=="
           mname=192.168.1.10
           zone=example.org
           domain=www
           a=${ec2_ip_address}
           op=add

Notes

This module requires dnspython (http://www.dnspython.org/), and it will typically be run as a local_action so as to not push the secret TSIG key all over the show.
