Kubernetes with minikube

Minikube is the easiest way to get yourself a dev friendly kubernetes setup. You can get download it from here and get yourself a kubernetes node by doing just minikube start

Of course, you need to have Virtualbox installed on your host machine.

Once you get minikube binary, some immediate checks you can do

  $ minikube start
  Starting local Kubernetes cluster...
  Kubectl is now configured to use the cluster.

  $ minikube status
  minikubeVM: Running
  localkube: Running

  $ minikube ip
  192.168.99.104

  $ minikube dashboard
  Opening kubernetes dashboard in default browser...

However, it installs boot2docker based docker host on your Virtualbox. If you prefer CoreOS like me, you can install it by running minikube start --iso-url=https://github.com/coreos/minikube-iso/releases/download/v0.0.4/minikube-v0.0.4.iso

You can also ssh into your minikube VM by running minikube ssh

minikube also lets you configure your docker environment easily so that you can connect to minikube’s docker daemon directly from your host machine.

  $ minikube docker-env
  export DOCKER_TLS_VERIFY="1"
  export DOCKER_HOST="tcp://192.168.99.104:2376"
  export DOCKER_CERT_PATH="/Users/karteek/.minikube/certs"
  export DOCKER_API_VERSION="1.23"
  # Run this command to configure your shell:
  # eval $(minikube docker-env)

And it configures kubectl automatically for you. So, you can start playing around with your kubernetes node immediately with in matter of minutes.

  $ kubectl get nodes
  NAME       STATUS    AGE
  minikube   Ready     3d

  $ kubectl cluster-info
  Kubernetes master is running at https://192.168.99.104:8443
  kubernetes-dashboard is running at https://192.168.99.104:8443/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard

  To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
