Cloudtopiaa Orchestration Service

The Orchestration service provides a template-based orchestration for describing a cloud application by running OpenStack API calls to generate running cloud applications. The software integrates other core components of OpenStack into a one-file template system. The templates allow you to create most OpenStack resource types such as instances, floating IPs, volumes, security groups, and users. It also provides advanced functionality such as instance high availability, instance auto-scaling, and nested stacks. This enables OpenStack core projects to receive a larger user base.

The service allows deployers to integrate with the Orchestration service directly or through custom plug-ins.

Launch an instance

In environments that include the Orchestration service, you can create a stack that launches an instance.

Create a template

The Orchestration service uses templates to describe stacks. To learn about the template language, see the Template Guide.

• Create the demo-template.yml file with the following content:

heat_template_version: 2015-10-15
description: Launch a basic instance with CirrOS image using the
           'm1.tiny' flavor, 'mykey' key,  and one network.

parameters:
NetID:
  type: string
  description: Network ID to use for the instance.

resources:
server:
  type: OS::Nova::Server
  properties:
    image: cirros
    flavor: m1.tiny
    key_name: mykey
    networks:
    - network: { get_param: NetID }

outputs:
instance_name:
  description: Name of the instance.
  value: { get_attr: [ server, name ] }
instance_ip:
  description: IP address of the instance.
  value: { get_attr: [ server, first_address ] }
