Chapter 3. Using the heat service for autoscaling After you deploy the services required to provide autoscaling in the overcloud, you must configure the overcloud environment so that the Orchestration service (heat) can manage instances for autoscaling. Prerequisites A deployed overcloud. For more information, see Section 2.2, "Deploying the overcloud for autoscaling" . Procedure Section 3.1, "Creating the generic archive policy for autoscaling" Section 3.2, "Configuring a heat template for automatically scaling instances" Section 3.3, "Preparing the standalone deployment for autoscaling" Section 3.4, "Creating the stack deployment for autoscaling" 3.1. Creating the generic archive policy for autoscaling After you deploy the services for autoscaling in the overcloud, you must configure the overcloud environment so that the Orchestration service (heat) can manage the instances for autoscaling. Prerequisites You have deployed an overcloud that has autoscaling services. For more information, see Section 2.1, "Configuring the overcloud for autoscaling" . Procedure Log in to your environment as the stack user. For standalone environments, set the OS_CLOUD environment variable: [stack@standalone ~]USD export OS_CLOUD=standalone For director environments source the stackrc file: [stack@undercloud ~]USD source ~/stackrc Create the archive policy defined in USDHOME/templates/autoscaling/parameters-autoscaling.yaml : USD openstack metric archive-policy create generic \ --back-window 0 \ --definition timespan:'4:00:00',granularity:'0:01:00',points:240 \ --aggregation-method 'rate:mean' \ --aggregation-method 'mean' Verification Verify that the archive policy was created: USD openstack metric archive-policy show generic +---------------------+--------------------------------------------------------+ | Field | Value | +---------------------+--------------------------------------------------------+ | aggregation_methods | mean, rate:mean | | back_window | 0 | | definition | - timespan: 4:00:00, granularity: 0:01:00, points: 240 | | name | generic | +---------------------+--------------------------------------------------------+ 3.2. Configuring a heat template for automatically scaling instances You can configure an Orchestration service (heat) template to create the instances, and configure alarms that create and scale instances when triggered. Note This procedure uses example values that you must change to suit your environment. Prerequisites You have deployed the overcloud with the autoscaling services. For more information, see Section 2.2, "Deploying the overcloud for autoscaling" . You have configured the overcloud with an archive policy for autoscaling telemetry storage. For more information, see Section 3.1, "Creating the generic archive policy for autoscaling" . Procedure Log in to your environment as the stack user. USD source ~/overcloudrc Create a directory to hold the instance configuration for the autoscaling group: USD mkdir -p USDHOME/templates/autoscaling/vnf/ Create an instance configuration template, for example, USDHOME/templates/autoscaling/vnf/instance.yaml .

Preparing the standalone deployment for autoscaling To test the deployment of a stack for an autoscaled instance in a pre-production environment, you can deploy the stack by using a standalone deployment. You can use this procedure to test the deployment with a standalone environment. In a production environment, the deployment commands are different.
