I created a deployment and defined a hpa rule for it: kubectl autoscale deployment my_deployment --min 6 --max 30 --cpu-percent 80. I want to run a command that editing the --min value, without remove and re-create a new hpa rule.Since kubernetes 1.16 there is a feature gate called HPAScaleToZero which enables setting minReplicas to 0 for HorizontalPodAutoscaler resources when using custom or external metrics. ... It can work alongside an HPA: when scaled to zero, the HPA ignores the Deployment; once scaled back to one, the HPA may scale up further. Share.There are at least two good reasons explaining why it may not work: The current stable version, which only includes support for CPU autoscaling, can be found in the autoscaling/v1 API version. The beta version, which includes support for scaling on memory and custom metrics, can be found in autoscaling/v2beta2.The HPA will maintain a minimum of 1 replica and a maximum of 10 replicas. To implement HPA in Kubernetes, you need to create a HorizontalPodAutoscaler object that references the Deployment you want to scale. You also need to specify the scaling metric and target utilization or value. Here’s an example of creating an HPA object for a Deployment:Want to stream video from your laptop onto your TV?

Behind the scenes, KEDA acts to monitor the event source and feed that data to Kubernetes and the HPA (Horizontal Pod Autoscaler) to drive the rapid scale of a resource. Each replica of a resource is actively pulling items from the event source. KEDA also supports the scaling behavior that we configure in Horizontal Pod Autoscaler.Mar 5, 2024 · A ReplicaSet is defined with fields, including a selector that specifies how to identify Pods it can acquire, a number of replicas indicating how many Pods it should be maintaining, and a pod template specifying the data of new Pods it should create to meet the number of replicas criteria. Kubernetes HPA Limitations. HPA can’t be used along with Vertical Pod Autoscaler based on CPU or Memory metrics.
