Introduction

This chart bootstraps an kube-downscaler deployment on a Kubernetes cluster using the Helm package manager.

Enable helm incubator repository

bash

helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator

Installing the Chart

To install the chart with the release name my-release into kube-system:

bash

helm install incubator/kube-downscaler --name my-release --namespace kube-system

The command deploys kube-downscaler on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

console

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.
