  • Set up minikube

• For production purpose, you can set up a Kubernetes cluster in one of the following ways:

  • Bootstrap your own cluster by following instructions in Installing Kubernetes with deployment tools in the Kubernetes documentation.

  • Provision a Kubernetes cluster from popular Cloud vendors:

    • Amazon Elastic Kubernetes Service
    • Microsoft Azure Kubernetes Service
    • IBM Cloud Kubernetes Service
    • Google Cloud Kubernetes Engine

kubectl tool

You need kubectl CLI tool installed on your local computer where you want to manage the Kubernetes cluster. For instructions on how to install the kubectl tool, see Install Tools in the Kubernetes documentation.
