description:
  Heat WordPress template to support F18, using only Heat OpenStack-native
  resource types, and without the requirement for heat-cfntools in the image.
  WordPress is web software you can use to create a beautiful website or blog.
  This template installs a single-instance WordPress deployment using a local
  MySQL database to store the data.

parameters:

  key_name:
