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.

Rationale

On my Windows machine, I wanted to follow the advice of a colleague and run MicroK8S to experiment with Kubernetes. I followed the advice on MicroK8S, and tried to use Multipass and found that it recommends using Hyper-V on Windows Hosts. Unfortunately, on my machine, I also use VirtualBox for some machines I've worked with, so I'm unable to use the Hyper-V based MultiPass. Multipass does allow a VirtualBox backend, however, it doesn't then bridge an interface, nor does it allow port forwarding.

Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.define "microk8s" do |microk8s|
    microk8s.vm.box = "ubuntu/bionic64"
    microk8s.vm.hostname = "microk8s"
    microk8s.vm.network "public_network", 
      use_dhcp_assigned_default_route: true

    microk8s.vm.provider "virtualbox" do |vb|
      vb.name = "microk8s"
      vb.memory = 4096
      vb.cpus = 2
    end
    
    microk8s.vm.provision "shell", inline: <<-EOF
      snap install microk8s --classic
      snap install docker
      microk8s.status --wait-ready
      microk8s.enable dns dashboard registry
      usermod -a -G microk8s vagrant
      echo "alias kubectl='microk8s.kubectl'" > /home/vagrant/.bash_aliases
      chown vagrant:vagrant /home/vagrant/.bash_aliases
      echo "alias kubectl='microk8s.kubectl'" > /root/.bash_aliases
      chown root:root /root/.bash_aliases
    EOF
  end
end
