# Kubernetes Autoscaler

[![Build Status](https://travis-ci.org/kubernetes/autoscaler.svg?branch=master)](https://travis-ci.org/kubernetes/autoscaler) [![GoDoc Widget]][GoDoc]

This repository contains autoscaling-related components for Kubernetes.

## What's inside

[Cluster Autoscaler](https://github.com/kubernetes/autoscaler/tree/master/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](https://github.com/kubernetes/autoscaler/tree/master/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 - under development.

[Addon Resizer](https://github.com/kubernetes/autoscaler/tree/master/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.
