About

Kubernetes is an open-source platform for automating deployment, scaling, and operations of application containers across clusters of hosts that provides container-centric infrastructure.

Learn how to:

  • Install Minikube
  • Run locally on Minikube 
  • Install Kubectl
  • Use the Kubectl CLI

Also, see why you’ll need more than Kubernetes for DevOps. Created by Red Hat’s own Daniel Oh for your ease.

Excerpt

To administer and interact with any given Kubernetes cluster (local or remote), you must set up your kubeconfig file. By default, kubectl con guration lives at ~/.kube/config

You can also create a cluster in your local machine via Minikube (See section 3: Running Locally via Minikube)
