Kubernetes Autoscaler
This repository contains autoscaling-related components for Kubernetes.
What's inside
Cluster Autoscaler - a component that automatically adjusts the size of a Kubernetes Cluster so that all pods have a place to run and there are no unneeded nodes. Works with GCP, AWS and Azure. Version 1.0 (GA) was released with kubernetes 1.8.
Vertical Pod Autoscaler - a set of components that automatically adjust the amount of CPU and memory requested by pods running in the Kubernetes Cluster. Current state - beta.
Addon Resizer - a simplified version of vertical pod autoscaler that modifies resource requests of a deployment based on the number of nodes in the Kubernetes Cluster. Current state - beta.
