Kubernetes KIND Cluster Setup

This guide walks you through installing and configuring a local Kubernetes cluster using kind (Kubernetes IN Docker).

---

Clone the repo:

git clone https://github.com/vanessasara/kubernetes-practice.git
cd k8s-in

1. Auto Dependencies Installation

Just run this file this make sure that your setup is ready to go with Docker, kind cluster and kubectl. Don't worry if docker is not installed it will install automatically.

# Install kubectl (Linux amd64)
./install.sh

Verify:

kubectl version --client --output=yaml
kind version

---

2. Create a KIND Cluster

Use a minimal single-node cluster or a multi-node config.

Single-node (control-plane only)

kind create cluster --name demo

Multi-node (1 control-plane + 2 workers)

Create or just run kind-config.yaml:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
    image: kindest/node:v1.33.1
  - role: worker
    image: kindest/node:v1.33.1
  - role: worker
    image: kindest/node:v1.33.1

Then:

kind create cluster --config kind-config.yml --name k8s-cluster

---

3. Verify Cluster

kubectl cluster-info --context kind-k8s-cluster
kubectl get nodes

Expected:

NAME                       STATUS   ROLES           AGE   VERSION
k8s-cluster-control-plane  Ready    control-plane   1m    v1.33.1
k8s-cluster-worker         Ready    <none>          1m    v1.33.1
k8s-cluster-worker2        Ready    <none>          1m    v1.33.1

🎉 CONGRATS!! you're ready to go with Kind cluster

🧭 Minikube Installation Guide for Ubuntu

This guide provides step-by-step instructions for installing Minikube on Ubuntu. Minikube allows you to run a single-node Kubernetes cluster locally for development and testing purposes.

---

🧰 Pre-requisites

Ensure the following before proceeding:

• Ubuntu OS

• sudo privileges

• Internet access

• Virtualization support enabled Check with:

  egrep -c '(vmx|svm)' /proc/cpuinfo

  • 0 = disabled
  • 1 = enabled

---

⚙️ Step 1: Update System Packages

Update your package lists to make sure you are getting the latest version and dependencies.

sudo apt update

---

📦 Step 2: Install Required Packages

Install some basic required packages.

sudo apt install -y curl wget apt-transport-https

---

🐳 Step 3: Install Docker

Minikube can run a Kubernetes cluster either in a VM or locally via Docker. This guide demonstrates the Docker method.

sudo apt install -y docker.io

Start and enable Docker.

sudo systemctl enable --now docker

Add current user to docker group (to use docker without root):

sudo usermod -aG docker $USER && newgrp docker

Now, logout (use exit command) and connect again.

---

🚀 Step 4: Install Minikube

First, download the Minikube binary using curl:

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

Make it executable and move it into your path:

chmod +x minikube
sudo mv minikube /usr/local/bin/

---

🧩 Step 5: Install kubectl

Download kubectl, which is a Kubernetes command-line tool.

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

Make it executable and move it into your path:

chmod +x kubectl
sudo mv kubectl /usr/local/bin/

---

🏗️ Step 6: Start Minikube

Now, you can start Minikube with the following command:

minikube start --driver=docker --vm=true

This command will start a single-node Kubernetes cluster inside a Docker container.

---

🔍 Step 7: Check Cluster Status

Check the cluster status with:

minikube status

You can also use kubectl to interact with your cluster:

kubectl get nodes

---

🛑 Step 8: Stop Minikube

When you are done, you can stop the Minikube cluster with:

minikube stop

---

🧹 Optional: Delete Minikube Cluster

If you wish to delete the Minikube cluster entirely, you can do so with:

minikube delete

---

🎉 Conclusion

That’s it! You’ve successfully installed Minikube on Ubuntu, and you can now start deploying Kubernetes applications for development and testing.
