[1] Deploy Instances with Heat services and templates. The example below is on the Controle Node.
# create a template for test

root@dlp ~(keystone)#
vi sample-stack.yml
heat_template_version: 2016-10-14

description: Heat Sample Template

parameters:
  ImageID:
    type: string
    description: Image used to boot a server
  NetID:
    type: string
    description: Network ID for the server

resources:
  server1:
    type: OS::Nova::Server
    properties:
      name: "Heat_Deployed_Server"
      image: { get_param: ImageID }
      flavor: "m1.small"
      networks:
      - network: { get_param: NetID }

outputs:
  server1_private_ip:
    description: IP address of the server in the private network
    value: { get_attr: [ server1, first_address ] }
