ZonedNS

What is it?

ZonedNS is a plugin for a CoreDNS that provides authoritative resolving using MySQL as a backend. The only real difference from other plugins is specific to A/AAAA mapping: it assumes you have certain "deployment zones", with fixed set of A/AAAA records, and domain names can be mapped to these zones ONLY.

How to use?

1. Follow CoreDNS build instructions, and add zonedns:github.com/raver119/zonedns to plugin.cfg
2. Provide MySQL credentials, i.e. via ENV in your K8S deployment description.

   DB_HOST="localhost"
   DB_USERNAME="xxxx"
   DB_PASSWORD="yyyyy"
   DB_NAME="database"
   

3. Add the plugin to your Corefile. I.e.:

.:1053 {
   cache 3600
   zonedns
}

In your management application:

1. Import the API package into your application: zonedns:github.com/raver119/zonedns-go-api
2. Use ZoneStorage or ZoneReader implementation to fetch/add/remove/update records/domains/zones in your app

Requirements:

• CoreDNS
• MySQL 8.x+
• Golang 1.13+
