# Helm Chart on Kubernetes

Deploy a Helm chart to an existing Kubernetes cluster with Pulumi in TypeScript, Python, Go, C#, YAML, or HCL.

The Helm Chart template scaffolds a Pulumi project that deploys a [Helm chart](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3) to an existing Kubernetes cluster using Pulumi's [Kubernetes provider](https://www.pulumi.com/registry/packages/kubernetes). The template creates a new namespace in the cluster and installs an Nginx ingress controller as the default chart, so the project deploys end to end out of the box.

## Using this template

To use this template, make sure you've already provisioned a [Kubernetes cluster](https://www.pulumi.com/dev/templates/kubernetes/), [installed Pulumi](https://www.pulumi.com/docs/install/) and [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/), and [configured your kubeconfig file](https://www.pulumi.com/registry/packages/kubernetes/installation-configuration#setup). Then create a new [project](https://www.pulumi.com/docs/iac/concepts/projects/) using the template in the language of your choice:

**TypeScript**

```bash
mkdir my-k8s-app && cd my-k8s-app
pulumi new helm-kubernetes-typescript
```

**Python**

```bash
mkdir my-k8s-app && cd my-k8s-app
pulumi new helm-kubernetes-python
```

**Go**

```bash
mkdir my-k8s-app && cd my-k8s-app
pulumi new helm-kubernetes-go
```

**C#**

```bash
mkdir my-k8s-app && cd my-k8s-app
pulumi new helm-kubernetes-csharp
```

**YAML**

```bash
mkdir my-k8s-app && cd my-k8s-app
pulumi new helm-kubernetes-yaml
```

**HCL**

```bash
mkdir my-k8s-app && cd my-k8s-app
pulumi new helm-kubernetes-hcl
```

Follow the prompts to complete the new-project wizard. When it's done, you'll have a complete Pulumi project that's ready to deploy and configured with the most common settings. Feel free to inspect the code in `index.ts` for a closer look.

## Deploying the project

The template requires no additional configuration. By default, it will install an Nginx ingress controller with Helm. Once the new project is created, you can deploy it with [`pulumi up`](https://www.pulumi.com/docs/iac/cli/commands/pulumi_up):

```bash
$ pulumi up
```

When the deployment completes, Pulumi exports the following [stack output](https://www.pulumi.com/docs/iac/concepts/stacks/#outputs) values:

**`name`**

The name of your new Helm chart deployment.

Output values like these are useful in many ways, most commonly as inputs for other stacks or related cloud resources.

## Customizing the project

Projects created with the Helm Chart template expose the following [configuration](https://www.pulumi.com/docs/iac/concepts/config/) settings:

**TypeScript / Python / Go / C# / YAML**

**`k8sNamespace`**

The name of the namespace to be created in your existing cluster. Defaults to `nginx-ingress`.

**HCL**

**`k8s_namespace`**

The name of the namespace to be created in your existing cluster. Defaults to `nginx-ingress`.

All of these settings are optional and may be adjusted either by editing the stack configuration file directly (by default, `Pulumi.dev.yaml`) or by changing their values with [`pulumi config set`](https://www.pulumi.com/docs/iac/cli/commands/pulumi_config_set):

**TypeScript / Python / Go / C# / YAML**

```bash
$ pulumi config set k8sNamespace my-namespace
$ pulumi up
```

**HCL**

```bash
$ pulumi config set k8s_namespace my-namespace
$ pulumi up
```

You can customize the Helm chart by passing values to it in your Pulumi code. An example of passing a few values to the chart is included in the template for reference.

## Cleaning up

You can cleanly destroy the stack and all of its infrastructure with [`pulumi destroy`](https://www.pulumi.com/docs/iac/cli/commands/pulumi_destroy):

```bash
$ pulumi destroy
```
