# This template does not yet work: not all of the software required is installed on NeCTAR images.

# A customization of one of the OpenStack sample templates
# at https://github.com/openstack/heat-templates/ for the NeCTAR environment


description: >
  This template demonstrates how to use OS::Heat::StructuredDeployment
  to apply config via os-apply-config. Note this requires your image to
  be built with the ntp element added (not included in the instructions
  in this repo by default, you'll have to add it and rebuild).
  This example includes additional configuration of cloud-init via
  the user-data in addition to the StructuredDeployment
