Apply a PowerDNS on Rails macro to a bunch of domains on the command line

_README.md

Bulk macros

Throw this script in the tmp directory of where your PowerDNS on Rails installation lives, make is executable and run like this:

$ ./tmp/apply-macro.rb 1 example.com example.org example.net

It will load the macro with ID 1, and apply it against each domain passed as CLI arguments.

apply-macro.rb

#!/usr/bin/env ruby

# Usage:
# ./tmp/apply-macro.rb MACRO_ID [domains [domain [domain]]]
# Pass all the domains as arguments to the script, or modify the script to read from a file...
