Kubernetes: the simple way

A simple script to bootstrap a kubernetes cluster based on kind and docker.

Prerequisites

Kind uses Docker to create cluster nodes. To install docker, please refer to: https://docs.docker.com/get-docker/

Usage

$ git clone https://github.com/abousselmi/k8s-kind.git
$ cd k8s-kind
$ sudo ./k8s-kind.sh -m start

Usage: ./k8s-kind.sh OPTION COMMAND

Options:
  -m      bootstrap a multi node cluster
  -s      bootstrap a single node cluster

Commands:
  start   setup kubernetes cluster
  stop    remove the current cluster
  help    print usage

Example:
  To bootstrap a multi node ckuster, you can do:
  sudo ./k8s-kind.sh -m start
