# nginx-ingress

[nginx-ingress](https://github.com/kubernetes/ingress/tree/master/controllers/nginx) is an Ingress controller that uses ConfigMap to store the nginx configuration.

To use, add the `kubernetes.io/ingress.class: nginx` annotation to your Ingress resources.

## TL;DR;

```console
$ helm install stable/nginx-ingress
```

## Introduction

This chart bootstraps an nginx-ingress deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

## Prerequisites
  - Kubernetes 1.4+ with Beta APIs enabled

## Installing the Chart

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

```console
$ helm install --name my-release stable/nginx-ingress
```

The command deploys nginx-ingress on the Kubernetes cluster in the default configuration. The [configuration](#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.

## Configuration

The following tables lists the configurable parameters of the nginx-ingress chart and their default values.

```console
$ helm install stable/nginx-ingress --name my-release \
    --set controller.stats.enabled=true
```

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
$ helm install stable/nginx-ingress --name my-release -f values.yaml
```

> **Tip**: You can use the default [values.yaml](values.yaml)
