git stash on a true branch
# 1. Store the "stash" on a branch
git checkout -b my-stashing-branch ## checkout, creating the branch
git add <the files to 'stash'>
git commit -m "comment" ## you now have the files on a branch
git push -u origin my-stashing-branch ## and saved in your central repo (GitHub)
# 2. Use your "stash" branch somewhere else.
git checkout somewhere-else
git merge my-stashing-branch --no-commit --no-ff ## origin/my-stashing-branch if new clone.

Local non-cloud cluster

This document describes how to run a Kraken Kubernetes cluster locally using Terraform, Vagrant, and Samsung vagrant and coreos providers.

The difference between running on a cloud environment (AWS) and locally is that instead of building a container and having that container connect to AWS (or other cloud) and running all the steps and possessing all the necessary software (Ansible, AWS client, terraform, terraform drivers, etc) the local host will run all of these steps and use a local hypervisor (Virtualbox by default) and use Samsung's terraform execute provider to run vagrant and provide it the necessary arguments for setting up the machines the cluster will run on. It should be noted that a docker container still runs on every virtual machine for the provisioning of that machine the same way the EC2 AMIs run docker to do the same.

OS X

On OS X, brew is the means of obtaining Terraform and other components:

Kraken - Local 'cluster' on Linux using VirtualBox

The following documents using Kraken to create a Kubernetes 'cluster' on a Linux host (Ubuntu 15.10) using VirtualBox+Vagrant as the technology to form the cluster, (of virtual machines).

Starting Point

Install Ubuntu 15.10 (Wily Werewolf) on a host that is capable of running VirtualBox to create virtual machines.
