16 Kubernetes Horizontal Pod Autoscaler

Kubernetes Horizontal Pod Autoscaler (HPA) allows automatic scaling (up and down) of the Oracle Access Management (OAM) servers. If load increases then extra OAM servers will be started as required, up to the value configuredManagedServerCount defined when the domain was created. Similarly, if load decreases, OAM 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 OAM cluster (accessdomain-oam-cluster), based on CPU utilization or memory resource metrics. If required, you can also perform the following for the accessdomain-policy-cluster.

Note:

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