Kubernetes Cluster Setup with Kind: Complete Local Development Guide

Introduction

Kind (Kubernetes IN Docker) is a tool for running local Kubernetes clusters using Docker containers as nodes. It’s perfect for local development, testing, and CI/CD pipelines. In this comprehensive guide, I’ll show you how to set up and use Kind for your Kubernetes development workflow.

What is Kind?

Kind is a tool designed to run Kubernetes clusters locally using Docker container “nodes”. Originally designed for testing Kubernetes itself, it’s now widely used for:

Local development and testing
CI/CD pipelines
Learning Kubernetes
Testing Kubernetes configurations

Key Features:

Fast cluster creation (< 1 minute)
Multi-node clusters support
Supports all Kubernetes versions
Minimal resource requirements
Easy cleanup

Prerequisites

Before we begin, ensure you have:

Docker installed and running
kubectl installed
Basic understanding of Kubernetes concepts
Terminal/command-line access

Installation verification:

docker --version
kubectl version --client

Installing Kind

macOS

# Using Homebrew
brew install kind

# Or using curl
curl -Lo ./kind https://kind.sigs.k8s.io/dl/latest/kind-darwin-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

Linux

# For AMD64 / x86_64
curl -Lo ./kind https://kind.sigs.k8s.io/dl/latest/kind-linux-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

# For ARM64
curl -Lo ./kind https://kind.sigs.k8s.io/dl/latest/kind-linux-arm64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

Windows

# Using Chocolatey
choco install kind

# Or download from GitHub releases
# https://github.com/kubernetes-sigs/kind/releases

Verify installation:

kind version

Creating Your First Cluster

Basic Single-Node Cluster

The simplest way to create a cluster:

kind create cluster

This creates a single-node cluster named “kind” by default.

Verify cluster:

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

Expected output:

NAME                 STATUS   ROLES           AGE   VERSION
kind-control-plane   Ready    control-plane   1m    v1.27.3

Creating a Named Cluster

kind create cluster --name my-cluster

List all clusters:

kind get clusters

Switch between clusters:

kubectl config use-context kind-my-cluster

Multi-Node Cluster Configuration

For more realistic testing, create a multi-node cluster using a configuration file.

Create Configuration File

Create kind-config.yaml:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
  - role: worker
  - role: worker
  - role: worker

Create cluster:

kind create cluster --name multi-node --config kind-config.yaml

Verify nodes:

kubectl get nodes

Output:

NAME                       STATUS   ROLES           AGE   VERSION
multi-node-control-plane   Ready    control-plane   2m    v1.27.3
multi-node-worker          Ready    <none>          2m    v1.27.3
multi-node-worker2         Ready    <none>          2m    v1.27.3
multi-node-worker3         Ready    <none>          2m    v1.27.3

Advanced Configuration

High Availability Control Plane

Create an HA cluster with multiple control plane nodes:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
  - role: control-plane
  - role: control-plane
  - role: worker
  - role: worker

Port Mapping for Services

Expose services on your host machine:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
    extraPortMappings:
      - containerPort: 30000
        hostPort: 30000
        protocol: TCP
      - containerPort: 30001
        hostPort: 30001
        protocol: TCP
  - role: worker

This allows you to access NodePort services at localhost:30000 and localhost:30001.

Custom Kubernetes Version

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
    image: kindest/node:v1.27.3@sha256:...
  - role: worker
    image: kindest/node:v1.27.3@sha256:...

Find available versions:

# Visit: https://github.com/kubernetes-sigs/kind/releases

Loading Local Docker Images

One of Kind’s best features is loading local images without pushing to a registry.

Build your image:

docker build -t my-app:latest .

Load into Kind cluster:

kind load docker-image my-app:latest --name my-cluster

Use in deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: my-app:latest
        imagePullPolicy: Never  # Important!

Setting Up Ingress

Install NGINX Ingress Controller

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml

Wait for ingress to be ready:

kubectl wait --namespace ingress-nginx \
  --for=condition=ready pod \
  --selector=app.kubernetes.io/component=controller \
  --timeout=90s

Create Ingress-Ready Cluster

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
    kubeadmConfigPatches:
      - |
        kind: InitConfiguration
        nodeRegistration:
          kubeletExtraArgs:
            node-labels: "ingress-ready=true"
    extraPortMappings:
      - containerPort: 80
        hostPort: 80
        protocol: TCP
      - containerPort: 443
        hostPort: 443
        protocol: TCP

Create cluster:

kind create cluster --config kind-ingress-config.yaml

Test ingress:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
spec:
  rules:
  - host: localhost
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: my-service
            port:
              number: 80

Access at: http://localhost

Persistent Storage

Kind supports persistent volumes using local storage.

Create StorageClass:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

Create PersistentVolume:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: local-pv
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  storageClassName: local-storage
  hostPath:
    path: /tmp/data

Cluster Management

Viewing Cluster Info

# Get cluster details
kind get clusters

# Get kubeconfig
kind get kubeconfig --name my-cluster

# Export kubeconfig
kind export kubeconfig --name my-cluster

Deleting Clusters

# Delete specific cluster
kind delete cluster --name my-cluster

# Delete all clusters
kind delete clusters --all

Best Practices

1. Use Configuration Files

Store cluster configs in version control
Makes cluster recreation consistent
Easy to share with team

2. Resource Management

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
  - role: control-plane
  - role: worker
    # Limit resources if needed
    extraMounts:
      - hostPath: /path/to/data
        containerPath: /data

3. Clean Up Regularly

# Remove unused clusters
kind delete cluster --name old-cluster

# Clean up Docker resources
docker system prune -a

4. Use Specific Versions

Pin Kubernetes versions in config
Ensures consistency across environments
Easier troubleshooting

5. Automate with Scripts

#!/bin/bash
# setup-kind.sh

# Create cluster
kind create cluster --name dev --config kind-config.yaml

# Install ingress
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml

# Wait for ingress
kubectl wait --namespace ingress-nginx \
  --for=condition=ready pod \
  --selector=app.kubernetes.io/component=controller \
  --timeout=90s

echo "Cluster ready!"

Troubleshooting

Cluster Won’t Start

# Check Docker is running
docker ps

# Check Docker resources
docker system df

# View Kind logs
kind create cluster --verbosity=3

Can’t Access Services

# Verify port mappings
docker ps

# Check service endpoints
kubectl get endpoints

# Test from within cluster
kubectl run test --image=busybox -it --rm -- wget -O- http://service-name

Image Pull Issues

# Verify image is loaded
docker exec -it kind-control-plane crictl images

# Reload image
kind load docker-image my-image:tag --name cluster-name

    steps:
      - uses: actions/checkout@v2
      
      - name: Create Kind cluster
        uses: helm/kind-action@v1.5.0
        with:
          cluster_name: test-cluster
      
      - name: Test deployment
        run: |
          kubectl apply -f k8s/
          kubectl wait --for=condition=ready pod -l app=myapp
          kubectl get pods
