# Kubernetes The Hard Way

This tutorial will walk you through setting up Kubernetes the hard way. This guide is not for people looking for a fully automated command to bring up a Kubernetes cluster. If that's you then check out [Google Container Engine](https://cloud.google.com/container-engine), or the [Getting Started Guides](http://kubernetes.io/docs/getting-started-guides/).

This tutorial is optimized for learning, which means taking the long route to help people understand each task required to bootstrap a Kubernetes cluster. This tutorial can be completed on the following platforms:

* [Google Compute Engine](https://cloud.google.com/compute)
* [Amazon EC2](https://aws.amazon.com/ec2)
* [Microsoft Azure](https://azure.microsoft.com)


> The results of this tutorial should not be viewed as production ready, and may receive limited support from the community, but don't let that prevent you from learning!

## Target Audience

The target audience for this tutorial is someone planning to support a production Kubernetes cluster and wants to understand how everything fits together. After completing this tutorial I encourage you to automate away the manual steps presented in this guide.

* This tutorial is for educational purposes only. There is much more configuration required for a production ready cluster.

## Cluster Details

* Kubernetes 1.3.6
* Docker 1.11.2
* [CNI Based Networking](https://github.com/containernetworking/cni)
* Secure communication between all components (etcd, control plane, workers)
* Default Service Account and Secrets


### What's Missing

The resulting cluster will be missing the following items:

* [Cluster add-ons](https://github.com/kubernetes/kubernetes/tree/master/cluster/addons)
* [Logging](http://kubernetes.io/docs/user-guide/logging)
* [No Cloud Provider Integration](http://kubernetes.io/docs/getting-started-guides/)

### Assumptions

GCP

* The us-central1 region will be used

```
gcloud config set compute/region us-central1
```

AWS

* The us-west-2 region will be used

Azure

* The "west us" region will be used

## Platforms

This tutorial assumes you have access to one of the following:

* [Google Cloud Platform](https://cloud.google.com) and the [Google Cloud SDK](https://cloud.google.com/sdk/) (125.0.0+)
* [Amazon Web Services](https://aws.amazon.com), the [AWS CLI](https://aws.amazon.com/cli) (1.10.63+), and [jq](https://stedolan.github.io/jq) (1.5+)
* [Microsoft Azure](https://azure.microsoft.com), the [Azure CLI](https://azure.microsoft.com/en-us/documentation/articles/xplat-cli-install/) (0.10.1+), and [jq](https://stedolan.github.io/jq) (1.5+)

## Labs

While GCP, AWS or Azure will be used for basic infrastructure needs, the things learned in this tutorial apply to every platform.
