Local development multi node Kubernetes Cluster for macOS made very simple
This project is not maintained anymore, please use minikube instead
Kube-Cluster for macOS is a status bar app
which allows in an easy way to bootstrap and control multi-node (master+ two nodes) Kubernetes cluster on three CoreOS VMs.
It leverages macOS native Hypervisor virtualisation framework of using corectl command line tool, so there are no needs to use VirtualBox or any other virtualisation software anymore.
Includes: Helm Classic / Helm v2 - The Kubernetes Package Manager and an option from shell to install Deis Workflow on top of Kubernetes: $ install_deis
Kube-Cluster App can be used together with CoreOS VM App which allows to build Docker containers and both apps have access to the same local Docker registry hosted by Corectl App.
App's menu looks as per image below:

file and drag the App e.g. to your Desktop. Start the Kube-Cluster

will run, then follow the instructions there.TL;DR

cli as well. Cli resides in ~/kube-cluster/bin
folder and has simple commands: kcluster start|stop|status|ip
. Just copy the kcluster
to your shell pre-set path.The install will do the following:

folder in the user's home folder e.g /Users/someuser/kube-cluster
corectl
to initialise VMfleetctl, kubectl, helm and deis
clients to ~/kube-cluster/bin/
~/kube-cluster/fleet
, this allows very easy updates to fleet units if needed.xxx-data.img
will be created and mounted to VMs as /data
for these mount binds and other folders:/data/var/lib/docker -> /var/lib/docker
/data/var/lib/rkt -> /var/lib/rkt
/var/lib/kubelet sym linked to /data/kubelet
/data/opt/bin
/data/var/lib/etcd2
/data/kubernetes
Just start Kube-Cluster
application and you will find a small icon with the Kubernetes logo in the Status Bar.

and OS Shell
OS Shell (terminal) will have such environment set:1) kubernetes master - export KUBERNETES_MASTER=http://192.168.64.xxx:8080
2) etcd endpoint - export ETCDCTL_PEERS=http://192.168.64.xxx:2379
3) fleetctl endpoint - export FLEETCTL_ENDPOINT=http://192.168.64.xxx:2379
4) fleetctl driver - export FLEETCTL_DRIVER=etcd
5) Path to ~/kube-cluster/bin where fleetctl, helmc, deis and kubectl are stored
Updates/Update Kubernetes to latest stable version

allows you to insatll any Kubernetes version available on github.com.Updates/Update macOS fleetctl, helmc and deis clients
will update fleetctl to the same versions as Kube-Cluster Master runs and helmc and deis to the latest versions.SSH to k8smaster01 and k8snode-01/02
