Using Vagrant with Multi-Node MicroK8S to experiment with Kubernetes

This script (using Vagrant) is used to build a pair of Ubuntu based virtual machines that have the MicroK8S setup of Kubernetes.

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

Please note that this script relies on the fact that Vagrant transfers files in /vagrant to the host file system, which we can then use to setup the second node.

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.
