Puppet sdiff module

A puppet module for suppressing diff output based on file and line patterns

Installation:

Install in your puppet master's modulepath as a directory named 'sdiff'. This will use the defaults or hiera if it has been configured.

include sdiff

You will need to add the following to your puppet.conf on each agent

[main]
.
.
.
.
diff=/usr/local/bin/sdiff
diff_args=-u

Usage:

For use with Hiera simply configure the following keys:

sdiff::file_pattern: '\.env'
sdiff::line_pattern: 'MERCHANT_ID=.*\|PRIVATE_KEY=.*\$'

If you want to pass in the values to the module, that is done as below:

class { 'sdiff':
  color        => false,
  file_pattern => '\.env',
  line_pattern => 'MERCHANT_ID=.*\|PRIVATE_KEY=.*\$',
}

When a file pattern is matched, sdiff will change

Suppressing potentially sensitive diff of /var/www/application/shared/config/staging.env vs /tmp/puppet-file20140314-24647-eem4az-0.

Line supression works similar but will only suppress matching lines.
