# Revision history [back]

I think what you're asking is how to pass parameters to an included sub-template.

When you call the sub-template, add some properties after the type. For instance, modifying your example:

scaleup_group:
type: OS::Heat::AutoScalingGroup
properties:
cooldown: 60
desired_capacity: 2
max_size: 5
min_size: 1
resource:
type: http://192.168.0.1/autoscaling/centos.yaml
properties:
flavor: m3.large


Or, of course, you could pass a user-supplied parameter using something like: flavor: {get_param: flavor}
