 # Install Vagrant on your Mac: https://www.vagrantup.com/

 # Here is the version I use
 $ vagrant --version
 Vagrant 1.8.1

 # Virtualbox (vbox) is the default Vagrant provider, so it should be installed with Vagrant.
 # I use vbox v5.0.16. If you need to install vbox, follow these directions: https://www.virtualbox.org/

 # Copy the Vagrant file in this gist to your laptop.
 # From the directory containing the Vagrant file, run:
 $ vagrant up

 # Note: You may be prompted to update your box. If so, do:
 $ vagrant box update

 # After your vagrant box completes the build is ready, ssh to it:
 $ vagrant ssh

 # Now you are ready to use kubeadm to configure the server.
 # Perform these steps:
 sudo su
 kubeadm init
 kubectl taint nodes --all dedicated-
 kubectl apply -f https://git.io/weave-kube

 # Ref: kubeadm guide: http://kubernetes.io/docs/getting-started-guides/kubeadm/
 #
 # Notes:
 # 1. You only need 1 vbox server for development purposes.
 # 2. Taint command is used, since there is only one node
 # 3. Make note of the kubeadm join command at the end of kubeadm init, in case you want to add nodes in future.
 #
 # Ensure everything comes up
