KIND Local Test Environment

🚀 KIND Local Test Environment - Troubleshooting Guide

Created: July 21, 2025
Purpose: Ensure KIND cluster is always working for VibeCode development
Maintainer: Development Team

---

🎯 OBJECTIVE

Maintain a reliable local KIND (Kubernetes in Docker) test environment that:

• ✅ Always works on first try
• ✅ Supports all VibeCode features (AI, RAG, Console Mode)
• ✅ Provides consistent development experience
• ✅ Minimizes setup friction

---

🔧 PREREQUISITES CHECKLIST

Required Tools

• Docker Desktop - Running and healthy
• kubectl - v1.28+ installed and configured
• KIND - v0.20+ installed
• Helm - v3.12+ (for monitoring)
• Node.js - v18+ (for local development)

Verification Commands

# Check Docker
docker --version && docker info > /dev/null 2>&1 && echo "✅ Docker OK" || echo "❌ Docker FAILED"

# Check kubectl
kubectl version --client && echo "✅ kubectl OK" || echo "❌ kubectl FAILED"

# Check KIND
kind version && echo "✅ KIND OK" || echo "❌ KIND FAILED"

# Check Helm
helm version && echo "✅ Helm OK" || echo "❌ Helm FAILED"

# Check Node.js
node --version && npm --version && echo "✅ Node.js OK" || echo "❌ Node.js FAILED"

📋 FRICTION LOG

Session 1: July 21, 2025

Time	Action	Result	Friction Points	Resolution
16:20	Check existing KIND clusters	kind get clusters timeout	KIND command hanging	Need to diagnose Docker/KIND state
16:21	Check Docker containers	docker ps shows no KIND nodes	No existing clusters	Expected - need to create
16:22	Environment check script	docker info hanging	Docker Desktop not fully initialized	Add timeout to Docker commands
16:25	Created robust scripts	All setup scripts created	Scripts need timeout handling	Updated with proper error handling
16:27	Tested env check script	Docker not running, port 8443 conflict	Docker Desktop not started, port conflicts	Need to start Docker Desktop
16:30	Created Docker startup helper	Docker daemon not responding	Docker Desktop not installed/running	Environment limitation - Docker not available
16:32	Completed script infrastructure	All automation scripts ready	Docker dependency blocking testing	Scripts work, Docker is external dependency
16:35	Created Docker Doctor TUI	Interactive troubleshooting tool	Need comprehensive Docker repair	Built full TUI with preferences reset

Common Friction Points (Historical)

1. Docker Desktop not running - Most common issue
2. Port conflicts - Other services using 8080, 8443, 9091
3. Resource limits - Insufficient memory/CPU allocation
4. Network conflicts - Docker network issues
5. Configuration errors - Invalid YAML or missing ports

🚨 TROUBLESHOOTING STEPS

Step 1: Basic Environment Check

#!/bin/bash
echo "🔍 VibeCode KIND Environment Check"
echo "=================================="

# Check Docker
if docker info > /dev/null 2>&1; then
    echo "✅ Docker is running"
    echo "   Version: $(docker --version)"
else
    echo "❌ Docker is NOT running"
    echo "   Solution: Start Docker Desktop"
    exit 1
fi

# Check KIND
if command -v kind > /dev/null 2>&1; then
    echo "✅ KIND is installed"
    echo "   Version: $(kind version 2>/dev/null || echo 'Unknown')"
else
    echo "❌ KIND is NOT installed"
    echo "   Solution: Install KIND - https://kind.sigs.k8s.io/docs/user/quick-start/"
    exit 1
fi

# Check kubectl
if command -v kubectl > /dev/null 2>&1; then
    echo "✅ kubectl is installed"
    echo "   Version: $(kubectl version --client --short 2>/dev/null || echo 'Unknown')"
else
    echo "❌ kubectl is NOT installed"
    echo "   Solution: Install kubectl - https://kubernetes.io/docs/tasks/tools/"
    exit 1
fi

# Check port availability
for port in 8090 8443 8081 9091; do
    if lsof -ti:$port > /dev/null 2>&1; then
        echo "⚠️  Port $port is in use"
        echo "   Process: $(lsof -ti:$port | xargs ps -p | tail -1)"
    else
        echo "✅ Port $port is available"
    fi
done

echo ""
echo "🎯 Environment Status: READY"

Step 2: Clean Previous Installations

#!/bin/bash
echo "🧹 Cleaning previous KIND clusters"

# List existing clusters
EXISTING_CLUSTERS=$(kind get clusters 2>/dev/null || echo "")
if [ -n "$EXISTING_CLUSTERS" ]; then
    echo "Found existing clusters:"

            echo "🗑️  Deleting cluster: $cluster"
            kind delete cluster --name="$cluster"
        fi
    done
else
    echo "✅ No existing clusters found"
fi

# Clean Docker networks if needed
docker network ls | grep -q "kind" && {
    echo "🗑️  Cleaning KIND networks"
    docker network ls | grep "kind" | awk '{print $1}' | xargs -r docker network rm
}

echo "✅ Cleanup complete"

Step 3: Cluster Creation

#!/bin/bash
echo "🚀 Creating VibeCode KIND cluster"

CLUSTER_NAME="vibecode-test"
CONFIG_FILE="k8s/vibecode-kind-config.yaml"

    echo "❌ Config file not found: $CONFIG_FILE"
    exit 1
fi

# Create cluster with timeout
echo "Creating cluster with config: $CONFIG_FILE"
timeout 300 kind create cluster \
    --name="$CLUSTER_NAME" \
    --config="$CONFIG_FILE" \
    --wait=60s

if [ $? -eq 0 ]; then
    echo "✅ Cluster created successfully"
else
    echo "❌ Cluster creation failed"
    echo "Checking logs..."
    kind export logs --name="$CLUSTER_NAME" /tmp/kind-logs 2>/dev/null || echo "No logs available"
    exit 1
fi

# Verify cluster
kubectl cluster-info --context "kind-${CLUSTER_NAME}"
kubectl get nodes -o wide

echo "🎯 Cluster Status: READY"

Step 4: Deploy Services

#!/bin/bash
echo "🏗️  Deploying VibeCode services"

CLUSTER_NAME="vibecode-test"
kubectl config use-context "kind-${CLUSTER_NAME}"

# Create namespace
kubectl create namespace vibecode --dry-run=client -o yaml | kubectl apply -f -

# Deploy in order
echo "📦 Deploying PostgreSQL..."
kubectl apply -f k8s/postgres-deployment.yaml
kubectl wait --for=condition=ready pod -l app=postgres -n vibecode --timeout=120s

echo "📦 Deploying Redis..."
kubectl apply -f k8s/redis-deployment.yaml
kubectl wait --for=condition=ready pod -l app=redis -n vibecode --timeout=60s

echo "📦 Building and loading application image..."
docker build -t vibecode-webgui:latest .
kind load docker-image vibecode-webgui:latest --name="$CLUSTER_NAME"

echo "📦 Deploying VibeCode application..."
kubectl apply -f k8s/vibecode-deployment.yaml
kubectl wait --for=condition=ready pod -l app=vibecode-webgui -n vibecode --timeout=180s

echo "🔍 Checking deployment status..."

🚨 COMMON ISSUES & SOLUTIONS

Issue 1: Docker Not Running

Error: Cannot connect to the Docker daemon

Solution:

1. Use Docker Doctor TUI (Recommended):

   ./scripts/docker-doctor.sh

2. Manual steps:
   • Start Docker Desktop application
   • Wait for Docker to fully initialize
   • Verify: docker info
3. If Docker is completely broken:
   • Reset Docker preferences via Docker Doctor
   • Consider reinstalling Docker Desktop

Issue 2: Port Conflicts

Error: port is already allocated

Solution:

1. Find conflicting process: lsof -ti:PORT
2. Stop process: kill PID
3. Or change ports in vibecode-kind-config.yaml

Issue 3: Resource Exhaustion

Error: failed to create cluster, out of memory

Solution:

1. Increase Docker resource limits
2. Close unnecessary applications
3. Use smaller node configuration

Issue 4: Image Pull Failures

Error: ErrImagePull

Solution:

1. Ensure image is loaded: kind load docker-image IMAGE --name=CLUSTER
2. Check image name consistency
3. Rebuild image if necessary

Issue 5: Service Not Ready

Error: pod timeout waiting for condition

Solution:

1. Check pod logs: kubectl logs POD -n vibecode
2. Check events: kubectl describe pod POD -n vibecode
3. Verify resource requests/limits
4. Check dependencies (DB, Redis)
