About
This guide was created following the awesome Kubernetes The Hard Way by Kelsey Hightower. It's a lot of copy pasting, so all credit to him.
I consulted Prabhat Sharma adaption of Kubernetes The Hard Way (AWS)
This guide also makes use of Terraform to automatically deploy the infrastructure and Ansible to provision it.
There are some shell and asible scripts provided to fully automate the whole process.
Kubernetes The Hard Way
This tutorial walks you through setting up Kubernetes the hard way. This guide is not for people looking for a fully automated command to bring up a Kubernetes cluster. If that's you then check out Google Kubernetes Engine, AWS Elastic Container Service for Kubernetes or the Getting Started Guides.
Kubernetes The Hard Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.
The results of this tutorial should not be viewed as production ready, and may receive limited support from the community, but don't let that stop you from learning!
Target Audience
The target audience for this tutorial is someone planning to support a production Kubernetes cluster and wants to understand how everything fits together.
