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.

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
