Create Kubernetes Cluster using Kubespray

This repository will create a Kubernetes Cluster, using Kubespray, so it can be used for a Lab Environment.

It will create 4 VMs:

• node0[1-3]: 1 k8s master and 2 worker nodes (2 vcpu and 4GB RAM each)
• controller: controller node (2 vcpu, 2GB RAM)

kubectl binary will be installed on the controller node.

This repository was tested using

Quick Start

Check the variables defined on the .env file.

NOTE: The bootstrap uses the ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub, so if you don't have these files, you need to create using:

ssh-keygen -t rsa

To create the k8s cluster just run:

vagrant up
vagrant provision --provision-with k8s

You can now connect to the controller node and use kubectl using:

vagrant ssh controller

kubectl cluster-info
