mkzone

mkzone generates bind zone files from yaml files.

The easiest way to learn how to use it is to look at the example yaml files. There are three in total covering a domain "example.com" and both IPv4 and IPv6 reverse zone files.

Forward zones

These are fairly straight forward:

origin: example.com.
ttl: 1h

soa:
    ns: ns.example.com.
    user: root.example.com.

records:
    - type: NS
      value: ns.example.com.

    - type: MX
      priority: 10
      value: mx.example.com.

    - type: A
      host: ns
      value: 203.0.113.1

    - type: AAAA
      host: ns
      value: 2001:db8::1

    - type: A
      host: mx
      value: 203.0.113.2

    - type: AAAA
      host: mx
      value: 2001:db8::2

    - type: A
      host: '@'
      value: 203.0.113.3

    - type: AAAA
      host: '@'
      value: 2001:db8::3

    - type: CNAME
      host: www
      value: example.com.

This example shows all the current record types supported at the moment. Once catch is that @ symbols need to be quoted. Could possibly avoid this somehow.

Reverse zones

Reverse zones are indicated by type: reverse:

origin: 203.0.113.0/24
ttl: 1h
type: reverse

soa:
    ns: ns.example.com.
    user: root.example.com.

records:
    - type: NS
      value: ns.example.com.

    - type: PTR
      host: ns.example.com.
      value: 203.0.113.1

    - type: PTR
      host: mx.example.com.
      value: 203.0.113.2

    - type: PTR
      host: example.com.
      value: 203.0.113.3

Reverse zones are processed a little differently. The origin needs to be in CIDR format. That is include the netmask. mkzone uses this to calculate the correct origin and host entries. Run ./mkzone examples/reverse.ip4.yml and you will get the idea.

Requirements

mkzone is written in Python 3. It also uses the ipaddress module which is only included in Python 3.3.2+ and only on a provisional basis. If your distro doesn't package Python 3.3.2+ try pyenv or something similar.
