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, 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!
This guide is based on original Kubernetes The Hard Way guide which leverage Google Cloud Platform.
The main differences are:
- AWS instead of GCP
- docker instead of container-d
- kubernetes 1.9.7 instead of 1.9.0
- one master and one worker, no load balancers
The target audience for this tutorial is someone planning to support a production Kubernetes cluster and wants to understand how everything fits together.
Kubernetes The Hard Way guides you through bootstrapping a highly available Kubernetes cluster with end-to-end encryption between components and RBAC authentication. Because not everyone have publicly available domain, we will build GOSSIP-only cluster.
- Kubernetes 1.9.7
- Docker Runtime 18.03.1-ce
- CNI Container Networking 0.6.0
- etcd 3.3.4
This tutorial assumes you have access to the AWS Cloud. While AWS is used for basic infrastructure requirements the lessons learned in this tutorial can be applied to other platforms.
