Where to find existing templates

There are several repositories where you can find existing HOT templates.

The OpenStack Heat Templates repository contains example templates demonstrating core Heat functionality, related image-building templates, and template-related scripts and conversion tools.

Rackspace has provided a set of Heat templates at the RCB Ops repository that can be used by cloud operators to launch applications, templates for building a multi-node OpenStack cluster, as well as templates for CI development. Heat templates for deployment of Magento, Hadoop, MongoDB, ELK, Drupal and more can be found here.
