We will need two tools on the client machine: the Cloud Flare SSL tool to generate the different certificates, and the Kubernetes client, kubectl, to manage the Kubernetes cluster. If you don't have a Linux desktop, you can use the HAProxy machine to do the same thing. I will use my Linux desktop as a client machine to generate all the necessary certificates, but also to manage the Kubernetes cluster. This range will be 10.30.0.0/16, but it is only internal to Kubernetes. We also need three Kubernetes master nodes. We will assign the IP 10.10.40.93 to this machine. The first machine needed is the machine on which the HAProxy load balancer will be installed. The machines will all be configured on the same network, 10.10.40.0/24, and this network needs to have access to the Internet. This tutorial will go through the steps allowing to work around this limitation.įor this lab, we will use a standard Ubuntu 16.04 installation as a base image for the seven machines needed.

One of these limitations is that it doesn't support multi-master (high availability) configuration. It is currently a work in progress and it has some limitations.

It is designed to help with the deployment of Kubernetes. Kubeadm is a tool which is part of the Kubernetes project.
