Puppet supports templates and templating via ERB, which is part of the Ruby standard library and is used for many other projects including Ruby on Rails. While it is a Ruby templating system, you do not need to understand much Ruby to use ERB.
Templates allow you to manage the content of template files, for example configuration files that cannot yet be managed directly by a built-in Puppet type. This might include an Apache configuration file, Samba configuration file, etc.
That looks easy right ? Well to be hones I’m not a Ruby programmer and I don’t know it that well but when I was developing templates I’ve asked guys who do know Ruby and not everything they advised was working.

Unfortunately when this facter variable will be used on Amazon ec2 instance the ip will be the local ip and not the public ip. As I’m quite new to Puppet I read the documentation and write a custom fact for this.
