##Usage

The simplest way to use this module is:

include consul_template

Or to specify parameters:

class { 'consul_template':
    service_enable   => false
    log_level        => 'debug',
    init_style       => 'upstart',
    consul_wait      => '5s:30s',
    consul_max_stale => '1s'
}

Watch files

To declare a file that you wish to populate from Consul key-values, you use the watch define. This requires a source .ctmpl file and the file on-disk that you want to update.

consul_template::watch { 'common':
    template      => 'data/common.json.ctmpl.erb',
    template_vars => {
        'var1' => 'foo',
        'var2' => 'bar',
    },
    destination   => '/tmp/common.json',
    command       => 'true',
}

##Limitations

Depends on the JSON gem, or a modern ruby.
