This is a BOSH release for spinning Kubernetes 1.12.0, using BOSH to orchestrate the "physical" nodes that comprise the various roles of a Kubernetes cluster (master and worker).

This is, at present, an investigative project, wherein I am attempting to learn how to assemble a working, highly-available Kubernetes cluster from first principles.

I am following Kelsey Hightower's Kubernetes the Hard Way write-up.

I am aware of other efforts to BOSH-ify Kubernetes, like kubo. This project does not aim to replace those other projects in any way, and if you find joy in using those projects, please continue using them.

This repository comes with some sample manifests to illustrate how one might configure a k8s deployment in the wild.

• tinynetes - A single-VM instance, all-in-one k8s "cluster", suitable for experimentation or CI/CD.

  

• labernetes - A multi-node cluster of combined master+worker nodes, suitable for shared lab exercises.

  

• prodernetes - A proper cluster with master and worker nodes on separate VMs, allowing one to scale the workers separately from the control plane. All aspects of the control plane are co-located (etcd, api, scheduler, and cmgr). Suitable for (possibly) some real-world prod use.

  

• hugernetes - A REALLY BIG CLUSTER that splits the etcd component out onto its own multi-node cluster, leaving the control plane VMs to run api, scheduler, and the controller manager. Suitable for (possibly) some real-world prod use.

  

These are found in the manifests/ directory, and can be deployed without further pre-processing (no Spruce... yet).

I am not currently accepting unrequested PR's or other contributions to this repository. As I said, this is a personal project, for exploring the world of Kubernetes through the lens of a BOSH director.

If you find this, and manage to get it to work for you, great! I'd love to hear from you, of your successes and struggles.
