Getting Started with Minikube: Your Local Kubernetes Playground

Kubernetes is the industry standard for container orchestration, but setting up a full cluster can be complex. Minikube makes it simple—letting you run a local Kubernetes cluster on your laptop or workstation. In this guide, you’ll learn how to install Minikube and deploy your very first app.

What is Minikube?

Minikube is a tool that lets you run a single-node Kubernetes cluster locally. It’s perfect for learning, prototyping, and development before deploying to a real production cluster.

Prerequisites

Operating System: Linux, macOS, or Windows
Virtualization: Enable VT-x/AMD-v in your BIOS if you want to use a VM driver
Package Managers: Homebrew (macOS), Chocolatey (Windows), or apt/yum (Linux)

1. Install Kubectl

Kubectl is the command-line tool to interact with Kubernetes clusters.

On Linux:

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
kubectl version --client

On macOS:

brew install kubectl
kubectl version --client

On Windows:

choco install kubernetes-cli
kubectl version --client

2. Install Minikube

On Linux:

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube version

On macOS:

brew install minikube
minikube version

On Windows:

choco install minikube
minikube version

3. Start Minikube Cluster

minikube start

This command will download a VM image and set up your cluster.
By default, it uses the Docker driver if available; you can specify another driver if needed (e.g., --driver=virtualbox).

4. Verify Your Cluster

Check the status:

minikube status

Check cluster info:

kubectl cluster-info

5. Deploy Your First App

Let’s deploy a simple Hello World app to your Minikube cluster.

Create a Deployment:

kubectl create deployment hello-minikube --image=kicbase/echo-server:1.0

Expose the Deployment as a Service:

kubectl expose deployment hello-minikube --type=NodePort --port=8080

View the App in Your Browser:

minikube service hello-minikube

This command opens the app in your default browser.

6. Useful Minikube Commands

View all pods:
```
  kubectl get pods
```
View all services:
```
  kubectl get svc
```
SSH into the minikube VM:
```
  minikube ssh
```
Stop Minikube:
```
  minikube stop
```
Delete the cluster:
```
  minikube delete
```

7. Troubleshooting Tips

If minikube start fails, try specifying a driver: minikube start --driver=docker or minikube start --driver=virtualbox
If you use Windows, make sure Hyper-V or VirtualBox is installed and enabled.
Use minikube logs to troubleshoot startup problems.
