# Heat - Vertical Scaling
## Getting started
1. Clone project
2. Go to the project directory
3. Create `.env` file
> * PORT
> * OPENSTACK_USERNAME
> * OPENSTACK_PASSWORD
> * OPENSTACK_USER_DOMAIN_ID
> * OPENSTACK_PROJECT_NAME
> * OPENSTACK_PROJECT_DOMAIN_ID
5. Run `npm start`
6. Create a heat template
7. Define a scaling resource using `OS::Heat::AutoScalingGroup`
8. Define an alarm and set the URL of this service to alarm's actions(alarm_action, ok_action, ...)
## Request parameters
- **action**: `up` or `down`
- **flavors**: List of flavors id or name
- **group**: Scaling resource's name
- **cooldown**: Cooldown period, in seconds (default: 0)
