heat_template_version: 2013-05-23

### A modified copy of
### https://github.com/openstack/heat-templates/tree/master/hot/software-config/example-templates
### Original: example-deploy-sequence.yaml
### Changes: Added some defaults, ie. a NeCTAR image
### It only works with images that have the full Heat software installed on them...
### None of the Nectar images do at the moment :(

###################################################################
# The example is designed to demo how software deployment to handle
# dependencies.
#
# The scenario:
#  deployment_c -- hosted on --> server_a
#  | (explicit depends on via depends_on property)
#  deployment_b -- hosted on --> server_b
#  | (implicit depends on via get_attr in input_values property)
#  deployment_a -- hosted on --> server_a
#
# So the right deployment sequence should be:
#  deployment_a (server_a)
#  -->
#  deployment_b (server_b)
#  -->
#  deployment_c (back to server_a)
#
# How to deploy the sample:
#
# 1. Create on image with element heat-config-script in
# 2. heat stack-create -f example-deploy-sequence.yaml sequence
# 3. heat stack-show sequence
