In every Kubernetes installation, there is support for an HPA resource and associated controller by default. The HPA control loop continuously monitors the configured metric, compares it with the target value of that metric, and then decides to increase or decrease the number of replica pods to achieve the target value.Solution. 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 {.In Kubernetes, a Service is a method for exposing a network application that is running as one or more Pods in your cluster.

Any HPA target can be scaled based on the resource usage of the pods in the scaling target.When defining the pod specification the resource requests like cpu and memory shouldbe specified. This is used to determine the resource utilization and used by the HPA controllerto scale the target up or down. That means that pods does not have any cpu resources assigned to them. Without resources assigned HPA cannot make scaling decisions. Try adding some resources to pods like this: spec: containers: - resources: requests: memory: "64Mi". cpu: "250m".In this article, you'll learn how to configure Keda to deploy a Kubernetes HPA that uses Prometheus metrics..
