Ansible Role for BIND DNS

This role is for setting up and managing BIND, which is a DNS server. Unlike other BIND roles for Ansible, this one uses Jinja templates for the zone database files instead of just copying files without changes. This feature is especially helpful for testing.

Requirements

This role works with Ansible version 2.4.0.0 and above and requires Ubuntu Server 14.04 or 16.04 on the systems where it will be used.

Role Variables

You can customize this role by changing the variables below. Check defaults/main.yml for the default values.

The main variable is the zones list. It outlines the zones served by BIND and the source template files used to create the zone database files.

zones:
  - {name: 'example.com', template_source: 'templates/db.example.com.j2'}
  - {name: 'example.net', template_source: 'templates/db.example.net.j2'}

The forwarders variable lists which servers will help resolve queries that this server is not responsible for.

forwarders:
  - 192.0.2.1
  - 203.0.113.1

The zone_transfer_peers variable indicates which other DNS servers can perform zone transfers from this server. Include any secondary name servers for the domains listed.

zone_transfer_peers:
  - 192.0.2.2
  - 203.0.113.2

Dependencies

This role does not depend on other Ansible roles.
