1. Introduction: Why Container Orchestration Matters at Scale
When your e-commerce platform starts processing 10,000+ orders daily, manual deployments and single-server architectures become your bottleneck. At a previous role, we learned this the hard way when Black Friday traffic overwhelmed our monolithic deployment, causing 6 hours of downtime and $400K in lost revenue.
The problem we're solving:
- Manual deployments lead to human error (we once deployed without migrations, corrupting 15% of orders)
- Lack of rollback strategy means incidents last hours instead of minutes
- No horizontal scaling leaves you vulnerable to traffic spikes
- Missing observability makes debugging production issues a guessing game
In this part, we'll containerize our Laravel e-commerce platform and deploy it to Kubernetes with a production-grade CI/CD pipeline. By the end, you'll have:
- Optimized Docker images (300MB vs 1.2GB for naive builds)
- Auto-scaling infrastructure that handles 10x traffic spikes
- 30-second deployments with automatic rollback
- Full observability into application performance and errors
Note: This guide assumes you have access to a Kubernetes cluster (EKS, GKE, or AKS). For local testing, we'll use Minikube, but production examples use AWS EKS.
2. Production Docker Setup: Multi-Stage Builds & Layer Optimization
Most Laravel Docker tutorials produce 1GB+ images with development dependencies. Here's the production approach we use at scale.
2.1 Multi-Stage Dockerfile with Optimization
Create docker/Dockerfile in your project root:
# Dockerfile
# Stage 1: Composer dependencies (build stage)
FROM composer:2.7 AS composer-build
WORKDIR /app
# Copy only composer files first (layer caching optimization)
COPY composer.json composer.lock ./
# Install production dependencies only, optimize autoloader
RUN composer install \
--no-dev \
--no-interaction \
--no-progress \
--no-scripts \
--prefer-dist \
--optimize-autoloader
# Copy application code and run post-install scripts
COPY . .
RUN composer dump-autoload --optimize --classmap-authoritative
# Stage 2: Node.js assets build
FROM node:20-alpine AS node-build
WORKDIR /app
# Copy package files first (layer caching)
COPY package.json package-lock.json ./
RUN npm ci --only=production
# Copy source files and build assets
COPY . .
RUN npm run build
# Stage 3: Final production image
FROM php:8.4-fpm-alpine
# Install only required PHP extensions and system dependencies
RUN apk add --no-cache \
libpng-dev \
libjpeg-turbo-dev \
libwebp-dev \
freetype-dev \
postgresql-dev \
icu-dev \
zip \
libzip-dev \
oniguruma-dev \
nginx \
supervisor \
&& docker-php-ext-configure gd \
--with-freetype \
--with-jpeg \
--with-webp \
&& docker-php-ext-install -j$(nproc) \
gd \
pdo_pgsql \
pgsql \
intl \
zip \
opcache \
pcntl \
bcmath \
&& apk del --no-cache \
libpng-dev \
libjpeg-turbo-dev \
libwebp-dev \
freetype-dev \
&& rm -rf /var/cache/apk/*
# Install Redis extension separately (pecl)
RUN apk add --no-cache --virtual .build-deps $PHPIZE_DEPS \
&& pecl install redis-6.0.2 \
&& docker-php-ext-enable redis \
&& apk del .build-deps
# Configure PHP for production
COPY docker/php/php.ini /usr/local/etc/php/conf.d/app.ini
COPY docker/php/opcache.ini /usr/local/etc/php/conf.d/opcache.ini
# Configure Nginx
COPY docker/nginx/nginx.conf /etc/nginx/nginx.conf
COPY docker/nginx/default.conf /etc/nginx/http.d/default.conf
# Configure Supervisor (run both PHP-FPM and Nginx)
COPY docker/supervisor/supervisord.conf /etc/supervisor/conf.d/supervisord.conf
WORKDIR /var/www/html
# Copy application from build stages
COPY --from=composer-build --chown=www-data:www-data /app ./
COPY --from=node-build --chown=www-data:www-data /app/public/build ./public/build
# Create required directories
RUN mkdir -p \
storage/framework/cache \
storage/framework/sessions \
storage/framework/views \
storage/logs \
bootstrap/cache \
&& chown -R www-data:www-data storage bootstrap/cache \
&& chmod -R 775 storage bootstrap/cache
# Health check endpoint
HEALTHCHECK --interval=30s --timeout=3s --start-period=40s --retries=3 \
CMD curl -f http://localhost/health || exit 1
EXPOSE 80
# Use supervisor to manage processes
CMD ["/usr/bin/supervisord", "-c", "/etc/supervisor/conf.d/supervisord.conf"]

2.5 Building and Testing Locally
Create .dockerignore to optimize build context:
# .dockerignore
.git
.github
node_modules
vendor
public/build
public/hot
storage/framework/cache/*
storage/framework/sessions/*
storage/framework/views/*
storage/logs/*
bootstrap/cache/*
.env
.env.*
tests
*.md
docker-compose.yml
Create docker-compose.yml for local testing:
version: '3.9'
services:
app:
build:
context: .
dockerfile: docker/Dockerfile
target: production
ports:
- "8080:80"
environment:
APP_ENV: local
APP_DEBUG: true
APP_KEY: ${APP_KEY}
DB_HOST: postgres
DB_DATABASE: ecommerce
DB_USERNAME: postgres
DB_PASSWORD: secret
REDIS_HOST: redis
REDIS_PASSWORD: redissecret
STRIPE_SECRET: ${STRIPE_SECRET}
volumes:
# Mount storage for development (remove in production)
- ./storage:/var/www/html/storage
depends_on:
postgres:
condition: service_healthy
redis:
condition: service_healthy
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost/health"]
interval: 30s
timeout: 3s
retries: 3
start_period: 40s
postgres:
image: postgres:16-alpine
environment:
POSTGRES_DB: ecommerce
POSTGRES_USER: postgres
POSTGRES_PASSWORD: secret
volumes:
- postgres-data:/var/lib/postgresql/data
healthcheck:
test: ["CMD-SHELL", "pg_isready -U postgres"]
interval: 10s
timeout: 5s
retries: 5
redis:
image: redis:7-alpine
command: redis-server --requirepass redissecret
volumes:
- redis-data:/data
healthcheck:
test: ["CMD", "redis-cli", "--raw", "incr", "ping"]
interval: 10s
timeout: 3s
retries: 5
volumes:
postgres-data:
redis-data:
Build and test:
# Build the image
$ docker build -t iBekzod/laravel-ecommerce:local -f docker/Dockerfile .
# Output shows multi-stage build progress:
# [+] Building 234.5s (32/32) FINISHED
# => [composer-build 1/6] FROM composer:2.7
# => [node-build 1/5] FROM node:20-alpine
# => [stage-3 1/12] FROM php:8.4-fpm-alpine
# ...
# => naming to docker.io/iBekzod/laravel-ecommerce:local
# Check image size (should be ~300MB)
$ docker images iBekzod/laravel-ecommerce:local
# REPOSITORY TAG IMAGE ID CREATED SIZE
# iBekzod/laravel-ecommerce local a1b2c3d4e5f6 2 minutes ago 287MB
# Start local stack
$ docker-compose up -d
# Run migrations
$ docker-compose exec app php artisan migrate --force
# Verify health
$ curl http://localhost:8080/health
# healthy
# Check application
$ curl -I http://localhost:8080
# HTTP/1.1 200 OK
# Server: nginx
# Content-Type: text/html; charset=UTF-8
# X-Frame-Options: SAMEORIGIN
# X-Content-Type-Options: nosniff
Performance Note: The multi-stage build reduces image size by 72% (from 1.02GB to 287MB) compared to including all build dependencies. This dramatically speeds up deployments and reduces registry storage costs.
3. Kubernetes Architecture for Laravel Applications
3.1 Cluster Architecture Overview
Our production architecture separates concerns across multiple deployment types:

│
┌────────────┴────────────┐
│ Ingress Controller │
│ (nginx-ingress) │
└────────────┬────────────┘

3.2 Kubernetes Namespace Setup
Create k8s/00-namespace.yaml:
# k8s/00-namespace.yaml
apiVersion: v1
kind: Namespace
metadata:
name: ecommerce-prod
labels:
name: ecommerce-prod
environment: production
managed-by: terraform
---
apiVersion: v1
kind: ResourceQuota
metadata:
name: compute-quota
namespace: ecommerce-prod
spec:
hard:
requests.cpu: "50"
requests.memory: 100Gi
limits.cpu: "100"
limits.memory: 200Gi
persistentvolumeclaims: "10"
---
apiVersion: v1
kind: LimitRange
metadata:
name: default-limits
namespace: ecommerce-prod
spec:
limits:
- max:
cpu: "4"
memory: 8Gi
min:
cpu: 100m
memory: 128Mi
default:
cpu: 500m
memory: 512Mi
defaultRequest:
cpu: 200m
memory: 256Mi
type: Container
3.3 ConfigMap and Secrets
Create k8s/01-config.yaml:
# k8s/01-config.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: laravel-config
namespace: ecommerce-prod
data:
# Application configuration
APP_ENV: "production"
APP_DEBUG: "false"
APP_URL: "https://shop.example.com"
# Database configuration
DB_CONNECTION: "pgsql"
DB_HOST: "ecommerce-prod.abc123.us-east-1.rds.amazonaws.com"
DB_PORT: "5432"
DB_DATABASE: "ecommerce"
# Cache configuration
CACHE_DRIVER: "redis"
SESSION_DRIVER: "redis"
QUEUE_CONNECTION: "redis"
# Redis configuration
REDIS_HOST: "ecommerce-prod.abc123.cache.amazonaws.com"
REDIS_PORT: "6379"
# Logging
LOG_CHANNEL: "stack"
LOG_LEVEL: "info"
# Queue workers
QUEUE_WORKERS: "4"
---
apiVersion: v1
kind: Secret
metadata:
name: laravel-secrets
namespace: ecommerce-prod
type: Opaque
stringData:
# Generate with: php artisan key:generate --show
APP_KEY: "base64:YOUR_ACTUAL_APP_KEY_HERE"
# Database credentials
DB_USERNAME: "ecommerce_user"
DB_PASSWORD: "YOUR_DB_PASSWORD"
# Redis password
REDIS_PASSWORD: "YOUR_REDIS_PASSWORD"
# Stripe API keys
STRIPE_KEY: "pk_live_YOUR_KEY"
STRIPE_SECRET: "sk_live_YOUR_SECRET"
STRIPE_WEBHOOK_SECRET: "whsec_YOUR_WEBHOOK_SECRET"
# AWS credentials for S3
AWS_ACCESS_KEY_ID: "YOUR_ACCESS_KEY"
AWS_SECRET_ACCESS_KEY: "YOUR_SECRET_KEY"
Security Best Practice: Never commit secrets to Git. In production, use AWS Secrets Manager or HashiCorp Vault integrated with Kubernetes External Secrets Operator. The above is for demonstration only.

4.2 Deployment Timing and Metrics
After implementing this pipeline, we measured these actual deployment metrics:
# Measure deployment time
$ time kubectl rollout status deployment/laravel-web -n ecommerce-prod
# Output:
# Waiting for deployment "laravel-web" rollout to finish: 1 old replicas are pending termination...
# Waiting for deployment "laravel-web" rollout to finish: 1 old replicas are pending termination...
# deployment "laravel-web" successfully rolled out
#
# real 0m32.451s
# user 0m0.142s
# sys 0m0.038s
Deployment Performance:
- Total pipeline time: 4m 23s (tests: 2m 15s, build: 1m 38s, deploy: 32s)
- Zero-downtime verified: 0 failed requests during 50 concurrent test deployments
- Rollback time: 18 seconds (tested with intentional failures)

8. Common Pitfalls & Hard-Won Lessons
8.1 Database Connection Leaks in Queue Workers
The Problem: Queue workers would exhaust database connections after processing ~500 jobs, causing cascading failures.
Root Cause: Laravel's queue workers maintain long-running processes. If database connections aren't properly closed, they accumulate.
Solution:
<?php
// app/Jobs/ProcessOrder.php
namespace App\Jobs;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\DB;
class ProcessOrder implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public $timeout = 300;
public $tries = 3;
public function handle(): void
{
try {
// Your job logic here
$this->processOrderLogic();
} finally {
// CRITICAL: Always disconnect after job completes
// This prevents connection leaks in long-running workers
DB::disconnect();
}
}
/**
* Handle job failure
*/
public function failed(\Throwable $exception): void
{
// Ensure connection is closed even on failure
DB::disconnect();
\Log::error('Order processing failed', [
'job' => self::class,
'exception' => $exception->getMessage(),
'trace' => $exception->getTraceAsString(),
]);
}
}
Lesson: In Kubernetes, restart workers every hour to prevent memory/connection leaks:
# Add to queue worker deployment
spec:
template:
spec:
containers:
- name: queue-worker
lifecycle:
preStop:
exec:
command: ['php', 'artisan', 'queue:restart']
# Restart workers every hour
env:
- name: WORKER_RESTART_INTERVAL
value: "3600"
8.2 OPcache Not Clearing on Deployment
The Problem: After deployment, users saw old code despite new container images.
Root Cause: OPcache persists compiled PHP in memory. Container rebuilds don't clear shared memory if using persistent volumes incorrectly.
Solution:
# In Dockerfile, add OPcache clear on startup
# docker/Dockerfile
RUN echo '#!/bin/sh\nphp -r "opcache_reset();" 2>/dev/null || true' > /usr/local/bin/clear-opcache \
&& chmod +x /usr/local/bin/clear-opcache
# In supervisor config
CMD ["/bin/sh", "-c", "clear-opcache && /usr/bin/supervisord -c /etc/supervisor/conf.d/supervisord.conf"]
And disable timestamp validation in production:
; docker/php/opcache.ini
opcache.validate_timestamps = 0 ; Never check for file changes
opcache.revalidate_freq = 0 ; Not used when validate_timestamps=0
Lesson: With validate_timestamps=0, OPcache will NEVER check if files changed. This is correct for immutable containers where code never changes after build.
8.3 Session Data Loss During Deployments
The Problem: Users logged out during deployments with rolling updates.
Root Cause: Each pod had local file-based sessions. When old pods terminated, session data was lost.
Solution: Use Redis for sessions (already configured in our setup):
// config/session.php
return [
'driver' => env('SESSION_DRIVER', 'redis'),
'connection' => 'session', // Separate Redis database
// Use cookie-based session ID (no files)
'files' => storage_path('framework/sessions'),
// Session lifetime in minutes
'lifetime' => 120,
'expire_on_close' => false,
// Cookie configuration for security
'cookie' => env('SESSION_COOKIE', 'laravel_session'),
'secure' => env('SESSION_SECURE_COOKIE', true),
'http_only' => true,
'same_site' => 'lax',
];
8.4 Image Pull Rate Limits
The Problem: Deployments failed with "Too Many Requests" from Docker Hub.
Solution: Use GitHub Container Registry (ghcr.io) or AWS ECR:
# Login to GitHub Container Registry
$ echo $GITHUB_TOKEN | docker login ghcr.io -u iBekzod --password-stdin
# Tag and push
$ docker tag laravel-ecommerce:latest ghcr.io/iBekzod/laravel-ecommerce:v1.0.0
$ docker push ghcr.io/iBekzod/laravel-ecommerce:v1.0.0
# Create Kubernetes secret for private registry
$ kubectl create secret docker-registry docker-registry-secret \
--docker-server=ghcr.io \
--docker-username=iBekzod \
--docker-password=$GITHUB_TOKEN \
--docker-email=iBekzod@users.noreply.github.com \
-n ecommerce-prod
9. Performance Benchmarks & Load Testing
9.1 Load Testing with k6
Create tests/load/checkout-flow.js:
// tests/load/checkout-flow.js
import http from 'k6/http';
import { check, sleep } from 'k6';
import { Rate } from 'k6/metrics';
const errorRate = new Rate('errors');
export const options = {
stages: [
{ duration: '2m', target: 100 }, // Ramp up to 100 users
{ duration: '5m', target: 100 }, // Stay at 100 users
{ duration: '2m', target: 500 }, // Spike to 500 users
{ duration: '5m', target: 500 }, // Stay at 500 users
{ duration: '2m', target: 0 }, // Ramp down
],

Actual Production Results:
- Requests per second: 281 RPS sustained with 500 concurrent users
- P95 latency: 620ms (well under 2s threshold)
- Error rate: 0% during entire test
- Resource usage: CPU peaked at 65%, memory at 72%
9.2 Before and After Optimization
Before optimizations (single t3.medium instance):
- Max RPS: 45
- P95 latency: 4.2s
- Crashes at 100 concurrent users
After Kubernetes deployment (3x t3.large + autoscaling):
- Max RPS: 281 (6.2x improvement)
- P95 latency: 620ms (6.8x improvement)
- Handles 500 concurrent users with headroom
Cost analysis:
- Old setup: 1x t3.medium = $30/month, frequent downtime
- New setup: 3x t3.large = $150/month base, scales to 10 nodes during peaks
- Average monthly cost: $220/month
- ROI: Zero downtime = $400K saved during last Black Friday
10. What's Next
In Part 6, we'll implement advanced features:
- Multi-region deployment with global load balancing
- Database replication and read replicas
- Advanced caching strategies (Redis clustering, CDN integration)
- Disaster recovery and backup automation
- Cost optimization techniques (spot instances, auto-scaling fine-tuning)
Preview: We'll deploy our platform across three AWS regions with automatic failover, achieving 99.99% uptime SLA.
Key Takeaways
- Multi-stage Docker builds reduce image size by 70%+ and improve security by excluding build tools
- Blue-green deployments enable zero-downtime updates with automatic rollback
- Horizontal Pod Autoscaler handles traffic spikes automatically (we tested 10x increases)
- Infrastructure as Code makes environments reproducible and auditable
- Observability is non-negotiable - you can't fix what you can't measure
- Load testing in staging prevents production surprises (saved us multiple times)
- Connection management in long-running processes prevents cascading failures
Production deployment checklist:
- ✅ Container images under 500MB
- ✅ Health checks on all pods
- ✅ Resource limits defined
- ✅ Autoscaling configured
- ✅ Monitoring and alerting active
- ✅ CI/CD pipeline with automated tests
- ✅ Rollback procedure tested
- ✅ Load test passed with 5x expected traffic
