# Prerequisites

## Google Cloud Platform

This tutorial leverages the [Google Cloud Platform](https://cloud.google.com/) to streamline provisioning of the compute infrastructure required to bootstrap a Kubernetes cluster from the ground up. [Sign up](https://cloud.google.com/free/) for $300 in free credits.

[Estimated cost](https://cloud.google.com/products/calculator/#id=78df6ced-9c50-48f8-a670-bc5003f2ddaa) to run this tutorial: $0.22 per hour ($5.39 per day).

> The compute resources required for this tutorial exceed the Google Cloud Platform free tier.

## Google Cloud Platform SDK

### Install the Google Cloud SDK

Follow the Google Cloud SDK [documentation](https://cloud.google.com/sdk/) to install and configure the `gcloud` command line utility.

Verify the Google Cloud SDK version is 183.0.0 or higher:

```
gcloud version
```

### Set a Default Compute Region and Zone

This tutorial assumes a default compute region and zone have been configured.

If you are using the `gcloud` command-line tool for the first time `init` is the easiest way to do this:

```
gcloud init
```

Otherwise set a default compute region:

```
gcloud config set compute/region us-west1
```

Set a default compute zone:

```
gcloud config set compute/zone us-west1-c
```

> Use the `gcloud compute zones list` command to view additional regions and zones.
