Reasons to upgrade to k8s 1.30
Container resource based autoscaling
Container resource based autoscaling is now promoted to stable https://github.com/kubernetes/enhancements/issues/1610 Horizontal Pod Autoscaler examines the total resource usage of the entire pod i.e. sum of all containers and scale pods based on average CPU or memory usage. Container resource based autoscaling feature allows HPA to scale workloads based on the resource usage of individual containers within a pod, instead of the aggregated usage of all containers in the pod
Aggregated Discovery
If you use Helm & Flux, you should consider upgrading to Kubernetes 1.30 which now offers GA Aggregated Discovery. This is particularly useful on clusters with many CRDs, where the number of API calls Helm SDK will decrease substantially.
