Hpa kubernetes
So the pod will ask for 200m of cpu (0.2 of each core). After that they run hpa with a target cpu of 50%: kubectl autoscale deployment php-apache --cpu-percent=50 --min=1 --max=10. Which mean that the desired milli-core is 200m * 0.5 = 100m. They make a load test and put up a 305% load.HPA Architecture. Introduction.

Jul 19, 2021 · Cluster Autoscaling (CA) manages the number of nodes in a cluster. It monitors the number of idle pods, or unscheduled pods sitting in the pending state, and uses that information to determine the appropriate cluster size. Horizontal Pod Autoscaling (HPA) adds more pods and replicas based on events like sustained CPU spikes. Oct 9, 2023 · Horizontal scaling is the most basic autoscaling pattern in Kubernetes. HPA sets two parameters: the target utilization level and the minimum or maximum number of replicas allowed. When the utilization of a pod exceeds the target, HPA will automatically scale up the number of replicas to handle the increased load.
