Application cookbook which manages iptables rules using confd.
The default recipe will install confd, iptables and create a iptables rules file which is created using a custom Chef resource provided by the confd cookbook. The included template is what is passed into confd to generate the iptables rules.
A fixture cookbook is
used to provide integration tests through Test Kitchen. These tests
can be invoked using bin/kitchen test centos-71. To see a list
of all the instances that we test on run bin/kitchen list.
