Using Vagrant with MicroK8S to experiment with Kubernetes

This Virtual Machine (using Vagrant) to build an Ubuntu based virtual machine that has the MicroK8S setup of Kubernetes.

It also installs docker, and sets up aliases for kubectl in line with the MicroK8S documentation.

Initially this should be functionally similar to MiniKube.

If you want a multi-node similar environment, here's a similar repository.

1. create a new repository in Github, don't add a readme or anything.

2. clone it on your computer

3. add the original repository (the one you want to fork) as upstream source.

   git remote add upstream [url]

4. fetch and merge upstream.

#Understanding closures, callbacks and promises

For a code newbie like myself, callbacks, closures and promises are scary JavaScript concepts.

10 months into my full-time dev career, and I would struggle to explain these words to a peer.

So I decided it was time to face my fears, and try to get my head around each concept.

Here are the notes from my initial reading. I'll continue to refine them as my understanding improves.

function cd {
    # Run the system CD command on the parameters that were passed in
    builtin cd "$@"
    # Check if the directory we are in now is a git directory
    if [ -d ".git" ]; then
        # If so, check to see that there are no uncommitted files
        if [ $(git status --porcelain 2>/dev/null| egrep "^(M| M)" | wc -l) ]; then
            # Rebase our current branch with upstream/master
            git fetch upstream && git rebase upstream/master
