Kubernetes Cluster template repository

Need a local Kubernetes cluster to quickly get to tinkering? Worry not, it is a mere vagrant up away.

This repository contains a cluster template to obtain a simple setup from scratch.

Two structure options:

• 1 master node, 3 worker nodes with disks (default)
• 1 master node, 3 worker nodes, 3 storage nodes with disks (enabled from the Vagrantfile)

Pre-requisites

The following need to be installed on the host machine:

• Vagrant
• Ansible
• VirtualBox as a default virtualization provider (libvirt is an alternative)

Starting the cluster

Start the cluster with the current Vagrantfile config:

vagrant up

Access the cluster's master node:

vagrant ssh demo-master-01

To change configuration settings (i.e. number of worker nodes), edit the Vagrantfile as necessary. Options include:

• Asymmetrical storage
• Memory used for VMs by category
• Disabling CNI install
• Changing the virtualization provider

Turn off the cluster and clean up its resources:

vagrant destroy -f

Cluster Features

• Uses the private subnet 192.168.56.0/24 for nodes and 10.244.0.0/16 for pods
• Each node equipped with 2 disks by default - either on workers or dedicated nodes
• Calico as a CNI
• Minimal other installs to leave room for your own!

Using libvirt

libvirt can be used as an alternate virtualization provider.

See Installing libvirt.
