Use ignore_changes to let Terraform know that the number of replicas is controlled by the autoscaler, and the deployment can safely ignore changes in replica count. Continuing the example above, we would modify our Terraform config to: resource "kubernetes_deployment" "my_deployment" {. metadata {.target: type: Utilization. averageUtilization: 60. Which according to the docs: With this metric the HPA controller will keep the average utilization of the pods in the scaling target at 60%. Utilization is the ratio between the current usage of resource to the requested resources of the pod. So, I'm not understanding something here.Kubernetes HPA custom scaling rules. I have a master-slave-like deployment, when the first pod starts (master node) it will be running on more powerful nodes and slaves on less powerful ones. I am doing it using affinity/anti-affinity.

Kubernetes HPA (Horizontal Pod Autoscaler) and VPA (Vertical Pod Autoscaler) are both tools used to automatically adjust the resources allocated to pods in a Kubernetes cluster. However, they differ in their approach and the resources they manage. The HPA adjusts the number of replicas of a pod based on the demand and ...
