Hi All, I'm converting a few heat service templates that have been working ok with puppet3 modules to run with Puppet 4, and am wondering if there is a way to pass an "undefined" default via heat to allow "default" values (eg params.pp) of the puppet modules to be used? The previous (puppet 3 working) way of passing an empty string in heat doesn't work, since Puppet 4 interprets this now as the actual setting. Thanks, Wojciech. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-dev/attachments/20180323/44650d3e/attachment.html>
