DDNS Ansible Playbook

Ansible playbook to orchestrate the deployment of a Docker-based Dynamic DNS solution, built on top of two separeted containers: a ISC DHCP container and a BIND container. Both containers may be hosted by the same or differente hosts.

How to use it

1. Either configure the existing or create your own hosts file following the example:

[dhcp]
dhcp.lan.example.com

[dns]
dns.lan.example.com

Note that the servers must run Ubuntu Server x86_64 12.04 or newer.

2. Configure the variables inside the following files:

• group_vars/all;

• group_vars/dhcp;

• group_vars/dns.

3. Generate a shared key to your DDNS deployment (you will need bind9utils installed in order to do that):

dnssec-keygen -a HMAC-MD5 -b 128 -r /dev/urandom -n USER DDNS_UPDATE
grep DDNS_UPDATE Kddns_update.*.key | cut -d' ' -f7

4. Now, store the key inside a environment variable called DDNS_SECRET, and run the playbook as usual:

DDNS_SECRET=<generated key> ansible-playbook -i <path to hosts file> --ask-become-pass site.yml
