Create an Intro guide for Kubernetes

[gcharters]

A static guide to describe OL and Kubernetes - a simple getting started.

Please strongly consider doing this using the IBM Cloud Private Community Edition. I would assume you would talk about using the helm chart that we already have for Open Liberty which is at: https://github.ibm.com/IBMPrivateCloud/charts/tree/master/stable/ibm-open-liberty. You could talk about building out a docker image via MicroClimate (the MSB part) but that might be a separate story.

Thank you, @herness. We will take this into consideration.

Eric's ask will also be addressed in ibm-cloud-architecture/refarch-cloudnative-kubernetes#78

@herness The primary focus of this guide will be to help developers understand how to deploy an applications to a kube runtime. That will focus on helm charts and similar. The particular kube runtime is not of critical importance to the learning activity. While IBM Cloud Private Community Edition could be used as the Kube runtime for the guide as it is not an open source project the Open Liberty guide won't focus on it. As Ian has indicated the use of Liberty technology in IBM Cloud Private will be covered through other avenues.

We still have mixed results from user testing though using Docker for Mac and Windows -- thanks to @irobins for the pointer -- does simplify prereq setup.

Upon further discussions and re-working, we will reorganize our efforts and split the work into the below:

• Kube Intro: Focussing on Kube; an introduction to it that is relevant to developers
• Kube + MP Config: How to externalize your config with MP and use them in a Kube env
• Kube + MP Health: How to report health statuses with MP and integrate with Kube

We believe the latter 2 guides are what will be useful to developers. We will focus the guides on what is relevant to developers and where MP and Kube intersect.

Repurposing this issue for a "Kube Intro" guide. "Kube + MP Config" and "Kube + MP Health" will be tracked by #173 and #174 respectively.
