Ansible Bind

• Manage bind config files. Zonefiles must be managed somewhere else.
• This role will solely copy the masterfiles from bind_lookup_zones.
• Build slaves from master without configuring zones.

Configuration:

Lookup path for master zone files on local ansible machine, relative to playbook.

bind_lookup_zones: path/to/zones_dir

ACLs

  some_random_networks:
    - 8.0.0.0/8
    - 169.254.0.0/16

Zones are defined as dict. The key is used as domain name.

• secondary is optional.
• type is defaulted to "master".
• When type is set to "slave", the secondary property is used as master.
