# Cloudinary-staging Chart packaged by Indiegogo
2+
3+
The Cloudinary-staging application is responsible for proxying the Cloudinary images in our Staging environment.
4+
5+
## TL;DR
6+
7+
```bash
8+
$ helm repo add indiegogo https://charts.indiegogo.com
9+
$ helm install my-release indiegogo/cloudinary-staging
10+
```
11+
12+
## Introduction
13+
14+
This chart bootstraps a Cloudinary-staging deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
15+
16+
## Prerequisites
17+
18+
- Kubernetes 1.12+
19+
- Helm 3.6.2
20+
21+
## Installing the Chart
22+
23+
To install the chart with the release name `my-release`:
24+
25+
```bash
26+
$ helm install my-release indiegogo/cloudinary-staging
27+
```
28+
29+
The command deploys Cloudinary-staging on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
30+
31+
> **Tip**: List all releases using `helm list`
32+
33+
## Uninstalling the Chart
34+
35+
To uninstall/delete the `my-release` deployment:
36+
37+
```bash
38+
$ helm uninstall my-release
39+
```
40+
41+
> NOTE: If you used `-n namespace` when you installed the chart, be sure to use it again when you uninstall the chart, otherwise the associated dependency Kubernetes resources will not be deleted:
42+
43+
```bash
44+
$ helm uninstall -n namespace my-release
45+
```
46+
47+
The command removes all the Kubernetes components associated with the chart and deletes the release.
48+
49+
