# Kubernetes Downscaler

This is a helm chart for [kube-downscaler](https://codeberg.org/hjacobs/kube-downscaler) deployment.

Please refer to the [official documentation](https://codeberg.org/hjacobs/kube-downscaler#user-content-command-line-options) for its usage.

## Adding Our Chart Repository

To add the Hahow charts for your local client, run helm repo add:

```console

$ helm repo add hahow https://hahow-helm-charts.storage.googleapis.com/

```

## Installing the Chart

To install the chart with the release name `my-release`:

```console

$ helm install my-release hahow/kube-downscaler

```

The command deploys postgres exporter on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.

## 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.
