Getting Started with Minikube: A Beginner's Guide to Kubernetes

Kubernetes has become a cornerstone in the world of container orchestration, enabling developers and operators to manage containerized applications seamlessly. To ease the learning curve and provide a local environment for Kubernetes development, Minikube comes into play. In this tutorial, we'll explore the basic commands and concepts to kickstart your journey with Minikube.

Prerequisites

Before you begin, make sure you have the following tools installed on your machine:

Minikube
kubectl
Docker

Step 1: Start Minikube

Open your terminal and run the following command to start Minikube:

minikube start

This initializes a local Kubernetes cluster within a virtual machine, providing a controlled environment for your development and testing.

Step 2: Check Minikube Status

Verify the status of your Minikube cluster by executing:

minikube status

This command provides information about the health and status of your Minikube cluster.

Step 3: Stop Minikube

When you're done working, stop Minikube to free up resources:

minikube stop
This halts the virtual machine, allowing you to resume your work later.

Step 4: Access Minikube VM

If you need direct access to the Minikube virtual machine, use:

minikube ssh

Default credentials for the Minikube VM are:

Username: docker
Password: tcuser

This grants you access to the VM's filesystem and configurations.

Step 5: Check Kubernetes Versions

To check the Kubernetes control plane and kubectl versions, run:

kubectl version

This ensures compatibility between your local environment and the Kubernetes cluster.

Step 6: Upgrade Kubernetes Versio

If you need to upgrade your Minikube Kubernetes version, use:

minikube start --kubernetes-version=v1.20.0

Replace v1.20.0 with the desired version to keep your Minikube cluster up-to-date.
