ubuntu@monasca-heat:~$ openstack orchestration template validate -t autoscaling.yaml
Environment:
event_sinks: []
parameter_defaults: {}
parameters: {}
resource_registry:
resources: {}
Description: 'Example of using monasca resources for auto-scale testing. In this template,
sample scale-group is created with given nova instance to auto-scale when cpu utilization
varies between 15 to 50 percent for 3 times consequently.
'
Parameters:
flavor:
Default: m1.nano
Description: Flavor for the instances to be created
Label: flavor
NoEcho: 'false'
Type: String
image:
Description: Name or ID of the image to use for the instances.
Label: image
NoEcho: 'false'
Type: String- Check flavor, image, and security_group IDs
