muresan / kubernetes-testbed

Vagrant Kubernetes testbed, uses ansible and kubeadm to build a cluster.

Kubernetes testbed

This repo has been created as a simple vagrant based testbed to aid familiarizing yourself with Kubernetes

It uses kubeadm to deploy a cluster, the Vagrantfile has a configurable number of managers and workers, but there's no multi-master setup so masters should be 1.

If you change number of workers you will need to vagrant destroy

Prerequisites

• Vagrant >=1.8.6
• Ansible >=2.0
• Virtualbox >=5.0 or libvirt (for libvirt you need VAGRANT_DEFAULT_PROVIDER=libvirt in your env)

Usage

Just do vagrant up

You will end up with 1 manager and 1 worker:

Vagrant Machine Name	K8s Role
m01	Master node
w01	Worker node
w02	Worker node

After vagrant up is done, you should be able to vagrant ssh <machinename> and issue kubectl get node (as root) to see the swarm nodes.
