How it works...

minikube is suitable for setting up Kubernetes on your macOS with the following command, which downloads and starts a Kubernetes VM stet, and then configures the kubectl configuration (~/.kube/config):

//use --vm-driver=hyperkit to specify to use hyperkit
$ /usr/local/bin/minikube start --vm-driver=hyperkit

//check whether .kube/config is configured or not
$ cat ~/.kube/config 
apiVersion: v1
clusters:
- cluster:
    certificate-authority: /Users/saito/.minikube/ca.crt
    server: https://192.168.64.26:8443
  name: minikube
contexts:
- context:
    cluster: minikube
    user: minikube
  name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
  user:
    as-user-extra: {}
    client-certificate: /Users/saito/.minikube/client.crt
    client-key: /Users/saito/.minikube/client.key

After getting all the necessary packages, perform the following steps:

1. Wait for a few minutes for the Kubernetes cluster setup to complete.
2. Use kubectl version to check the Kubernetes master version and kubectl get cs to see the component status.
3. Also, use the kubectl get nodes command to check whether the Kubernetes node is ready or not:

//it shows kubectl (Client) is 1.10.1, and Kubernetes master (Server) is 1.10.0
$ /usr/local/bin/kubectl version --short
Client Version: v1.10.1
Server Version: v1.10.0


//get cs will shows Component Status
$ kubectl get cs
NAME                 STATUS    MESSAGE              ERROR
controller-manager   Healthy   ok                   
scheduler            Healthy   ok                   
etcd-0               Healthy   {"health": "true"}   


//Kubernetes node (minikube) is ready
$ /usr/local/bin/kubectl get nodes
NAME       STATUS    ROLES     AGE       VERSION
minikube  Ready  master 2m v1.10.0

1. Now you can start to use Kubernetes on your machine. The following sections describe how to use the kubectl command to manipulate Docker containers.
2. Note that, in some cases, you may need to maintain the Kubernetes cluster, such as starting/stopping the VM or completely deleting it. The following commands  maintain the minikube environment:

For example, minikube starts a dashboard (the Kubernetes UI) by the default. If you want to access the dashboard, type minikube dashboard; it then opens your default browser and connects the Kubernetes UI, as illustrated in the following screenshot:
