Kubernetes multi-node cluster with Vagrant + Virtualbox + Kubeadm

Virtualbox + Vagrant + kubectl have to be installed on the host machine as a prerequisite (see 00-Prerequisites)

All the istructions here after have to be run on the host machine.

Install vagrant plugins

$ vagrant plugin install vagrant-vbguest
$ vagrant plugin install vagrant-reload
$ vagrant plugin install vagrant-hostmanager

If you installed the latest versions of Vagrant (2.2.6) and VirtualBox (6.1.x) you may face compatibility problems. To avoid them you can follow this guide: https://blogs.oracle.com/scoter/getting-vagrant-226-working-with-virtualbox-61-ga

Provision the environent

$ cd vagrant
vagrant$ vagrant up

Test the environment

vagrant$ export KUBECONFIG=$(pwd)/kubeconfig.yaml
vagrant$ kubectl get nodes

NAME     STATUS   ROLES    AGE   VERSION
master   Ready    master   18h   v1.15.3
node1    Ready    <none>   17h   v1.15.3
node2    Ready    <none>   17h   v1.15.3

Download kuberang utility here and test the cluster

vagrant$ ./kuberang
