Dnsmasq Local Cookbook

Installs Dnsmasq with an opinionated default configuration geared toward
localhost-only improved DNS reliability.

Requirements

This cookbook currently supports Ubuntu only.

At least for the time being, it supports Chef 11+, at the expense of some
additional complexity to maintain backwards compatibility.

Usage

Set the attributes you wish and add the default recipe to your run list, or
create a recipe of your own that implements the included Chef resources.

Recipes

default

Installs and configures Dnsmasq in an attribute-driven fashion.

Attributes

default

default['dnsmasq_local']['config'] = {}

Any key+value can be set under this namespace and it will be merged into the
default Dnsmasq config.

Any config key that contains a hyphen (e.g. cache-size) should be set in
attributes with an underscore (e.g. cache_size).

Any Dnsmasq setting that is a boolean key with no value (e.g. proxy_dnssec)
can be set to true or false to be enabled or disabled, respectively.
