15 Kubernetes Horizontal Pod Autoscaler

Kubernetes Horizontal Pod Autoscaler (HPA) allows automatic scaling (up and down) of the Oracle Identity Governance (OIG) servers. If load increases then extra OIG servers will be started as required, up to the value configuredManagedServerCount defined when the domain was created. Similarly, if load decreases, OIG servers will be automatically shutdown.

For more information on HPA, see Horizontal Pod Autoscaling.

The instructions below show you how to configure and run an HPA to scale an OIG cluster (governancedomain-oim-cluster), based on CPU utilization or memory resource metrics. If required, you can also perform the following for the governancedomain-soa-cluster.

Note:

If you enable HPA and then decide you want to start,stop, or scale OIG servers manually as per Scaling OIG Pods, it is recommended to delete HPA beforehand as per Deleting HPA.
