Basic Heat templates for AutoScaling

Eg. #1. deploy a simple stack to create a VM and attach to an existing Volume.

NOTE: to create a new Volume, use Horizon dashboard or use CLI:

• $ nova help volume-attach
• $ nova volume-attach 'SERVER' 'VOLUME' 'DEVICE'

Eg. #2. deploy a simple stack to create a VM and a Volume to attach

Eg. #3. deploy an autoscale stack to apply

• stress a node (eg, $ cat /dev/zero > /dev/null )
• verify Ceilometer metrics
• confirm the instantiation of new nodes
• stop the stress load on the node
• confirm the stop of the instantiated nodes due to stress

ffs - deploy an AutoScale NLB with Floating IP

2. Adapt customized parameters to your platform, eg: keypair, images, flavors

• $ nova keypair-list list
• $ openstack image list
• $ openstack flavor list
