# Helm

This quickstart will show you how to deploy Pomerium with Helm. For the purpose of this guide, we will be using Google's Kubernetes Engine. However, there are many other ways to work with Kubernetes:

- [Google Kubernetes Engine (GKE)](https://cloud.google.com/kubernetes-engine/)
- [Azure Kubernetes Service](https://azure.microsoft.com/en-us/services/kubernetes-service/)
- [Amazon Elastic Kubernetes Service (Amazon EKS)](https://aws.amazon.com/eks/)
- [OpenShift Kubernetes](https://www.openshift.com/learn/topics/kubernetes/)
- Or locally, with [minikube](https://kubernetes.io/docs/setup/minikube/)

Most of the following steps should be very similar using any other provider, but may require additional tweaks. 


## Prerequisites

- A [Google Cloud Account](https://console.cloud.google.com/)
- A configured [identity provider]
- Install [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
- Install the [Google Cloud SDK](https://cloud.google.com/kubernetes-engine/docs/quickstart)
- Install [helm](https://helm.sh/docs/using_helm/)

## Download

Retrieve the latest copy of pomerium's source-code by cloning the repository.

```bash
git clone https://github.com/pomerium/pomerium.git $HOME/pomerium
```

## Configure

Edit the the install command in the [helm_gke.sh script ][./scripts/helm_gke.sh] to match your [identity provider] settings.


Generate a wild-card TLS certificate. If you don't have one handy, the included [script] generates one from [LetsEncrypt].

## Run

Run [./scripts/helm_gke.sh] which will:

1. Provision a new cluster
2. Create authenticate, authorize, and proxy [deployments](https://cloud.google.com/kubernetes-engine/docs/concepts/deployment).
3. Provision and apply authenticate, authorize, and proxy [services](https://cloud.google.com/kubernetes-engine/docs/concepts/service).
4. Configure an ingress, Google's default load balancer.

```bash
sh ./scripts/helm_gke.sh
```

You should see roughly the following in your terminal. Note, provisioning does take a few minutes.

And if you check out Google's Kubernetes Engine dashboard you'll see something like:

## Navigate

Open a browser and navigate to `httpbin.corp.example.com`.

You should see something like the following in your browser.
