## What it is
A single-file shell script that installs Kubernetes high-availability clusters based on kubeadm with one command, including server initialization and optional addon components. It supports offline deployment, cluster upgrades, certificate renewal, and adding or removing nodes.

## Use cases
- install a kubernetes HA cluster with one command
- deploy k8s without ansible or python dependencies
- set up a kubernetes cluster in an air-gapped offline environment
- add or remove worker nodes from an existing kubeadm cluster
- renew kubernetes cluster certificates
- install ingress, network, storage, and monitoring addons alongside k8s
- initialize servers for kubernetes with kernel and sysctl tuning

## When to choose
- you want a lightweight, dependency-free shell script instead of ansible playbooks
- you need fast one-command kubeadm-based HA cluster deployment
- you must install kubernetes on servers without internet access using offline packages
- you want bundled installation of common addons like calico, ingress, and dashboard

## When to avoid
- you need declarative, idempotent infrastructure management at scale
- your environment requires managed kubernetes or gitops workflows
- you need support for operating systems outside the supported centos/debian/ubuntu list
- you prefer tools like kubespray, k3s, or kubeadm directly with custom automation
