Hi all:
I have a problem about openstack autoscaling by template! I have added 4 network in my sysytem (from horizon web portal):
Int_1 172.168.1.0/24;
Int_2 172.168.0.0/24;
subnet_heat_one 80.80.80.0/24;
ext_subnet 10.144.146.0/23;
I wrote autoscaling template and want to test autoscaling function and the template as follow:
HeatTemplateFormatVersion: '2012-12-12'
Description: Creates an autoscaling wordpress application using Ceilometer.

Type: String
Default: m1.small
AllowedValues: [m1.tiny, m1.small, m1.medium, m1.large, m1.xlarge]
ConstraintDescription: must be a valid EC2 instance type.
