DNScode

Simplifying DNS Zone management

---

About

DNScode is a project to help simplify DNS zone management, when using plain text files with servers like BIND and NSD. It provides a framework for programmatically generating zone files with Python, allowing for more flexability, compared to other DNS as code solutions.

Installation

 bash
# Create working directory
mkdir dnsproject
cd dnsproject
 
# Create virtual envrionment (optional, but highly recomended)
python3 -m venv .venv
source .venv/bin/activate
 
# Install the dnscode package
pip install dnscode

Usage

Import the dnscode package into a python script, create a zone object, then add records into the zone. Records can be added either via helper functions in the dnscode.Zone class, or by manually creating record objects and adding them through dnscode.Zone.add(). Both methods are shown in the example below.

Once the zone is setup, you can save it as a text file using dnscode.Zone.save_file(). Currently, it also outputs to to STDOUT. See https://code.minecraftchest1.us/minecraftchest1/dnscode/issues/5 for details.

import dnscode
 
zone = dnscode.Zone(origin='example.com')               # Create zone object
zone.new_SOA(mname='ns1.minecraftchest1.us.',           # Create SOA
    rname='admin.minecraftchest1.us.',
    refresh=onemonth, retry=oneday, ttl=oneday)
zone.new_A(name='myhost', ttl=3600, host='0.0.0.0')     #New A record
zone.new_AAAA(name='myhost', ttl-3600, hosts='::1')
# More helper functions in the docs
 
cname = dnscode.CNAME(name='mycname', ttl=60, host='example.com')
# More record objects in the docs.
zone.add(cname)
 
zone.save_file('example.zone')
