Kubernetes Setup Using Ansible and Vagrant

A complete local Kubernetes cluster with one master and two workers for testing purposes. Ansible playbooks will be used for provisioning.

Prerequisites

Vagrant : https://www.vagrantup.com/downloads.html
VirtualBox : https://www.virtualbox.org/wiki/Downloads
Ansible: https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

Setup overview

Vagrant up will deploy one master node and two workers using Ubuntu Xenial with 2 CPUs and 1GB of memory with static IPs:

• master 172.16.30.2
• node-1 172.16.30.3
• node-2 172.16.30.4

vagrant status
Current machine states:

master                    running (virtualbox)
node-1                    running (virtualbox)
node-2                    running (virtualbox)

Ansible playbooks will provision all necessary packages, initialize the master and join the nodes to Kubernetes cluster.

The kubernetes cluster have the following features by default:

• Kubernetes control plane (1.13.1)
• Calico networking CNI v3.7
• kubectl bash completion

To setup this cluster:

https://github.com/melina/k8s-homelab.git
cd k8s-homelab
vagrant up

Kubernetes cluster should be up and running:

kubectl get nodes
NAME     STATUS   ROLES    AGE    VERSION
master   Ready    master   115m   v1.13.1
node-1   Ready    <none>   87m    v1.13.1
node-2   Ready    <none>   84m    v1.13.1
