## What it is
The official installer CLI for provisioning OpenShift 4.x Kubernetes clusters across many platforms including AWS, Azure, GCP, bare metal, vSphere, and OpenStack. It guides users through interactive prompts or an install-config.yaml to create a fully configured cluster.

## Use cases
- install an openshift 4 cluster on aws
- provision openshift on bare metal
- deploy kubernetes cluster on vsphere
- create openshift cluster from install-config.yaml
- automated openshift cluster provisioning in ci
- install openshift on openstack or gcp

## When to choose
- you need to stand up a complete OpenShift 4.x cluster on a supported cloud or virtualization platform
- you want an opinionated, supported installer that handles infrastructure provisioning and bootstrap automatically
- you need repeatable, scriptable cluster installs via install-config.yaml

## When to avoid
- you only need vanilla upstream Kubernetes without OpenShift features
- your target platform is not among the supported providers
- you want a lightweight tool to manage already-running clusters rather than install new ones
