## What it is
Documentation and Vagrant-based installers for deploying Kubernetes clusters on CoreOS Container Linux, including single-node, multi-node, and bare-metal setups. The project is explicitly deprecated and superseded by Tectonic Installer and kube-aws.

## Use cases
- set up a kubernetes cluster on coreos container linux
- run a local multi-node kubernetes cluster with vagrant
- install kubernetes on bare metal
- learn how to deploy kubernetes with TLS and DNS configured
- run kubernetes conformance tests

## When to choose
- studying historical CoreOS Kubernetes deployment approaches
- referencing legacy cluster setup patterns

## When to avoid
- deploying a new production Kubernetes cluster
- wanting maintained or up-to-date tooling
- needing ongoing cluster maintenance and updates

## Facets
- artifact type: infra-config
- maturity: abandoned
- function: container-orchestration, deployment, documentation, infrastructure-as-code
- domain: cloud-computing, documentation
- platform: cloud, self-hosted
- tags: kubernetes, coreos, vagrant, cluster-setup, deprecated, containers, devops, linux, docker
