PHP and Kubernetes: Orchestration and Deployment of Modern Applications

The book "PHP and Kubernetes" is a practical guide that bridges the gap between traditional PHP development and modern cloud infrastructure. If you want to migrate your application from shared hosting or VPS to a flexible, scalable Kubernetes platform, this book will be your reliable assistant.

What is this book about?

The author consistently guides the reader from the basics of containerizing PHP applications to the full lifecycle of production operation. You will learn how to properly package PHP code into Docker images, configure Composer autoloading, and handle sessions and caching in a distributed environment. Special attention is paid to typical problems of PHP projects in Kubernetes: state management (stateful applications), handling file uploads, working with queues and background tasks.

Who is this book for?

• PHP developers who want to master modern methods of deploying and scaling their projects.
• DevOps engineers who need to adapt PHP applications for operation in a Kubernetes cluster.
• Team Leads and architects planning migration from a monolith to a microservice architecture.
• Administrators responsible for the stability and performance of high-load PHP projects.

What will you learn?

• How to build a lightweight and secure Docker image for PHP 8.x optimized for production.
• Principles of developing Helm charts for PHP applications: environment variables, secrets, config maps.
• Setting up horizontal pod autoscaling (HPA) based on CPU and memory load.
• Integration of PHP-FPM with Ingress controllers and load balancers.
• Organizing CI/CD pipelines using GitLab CI, Jenkins, or GitHub Actions for automatic deployment to Kubernetes.
• Monitoring and logging: Prometheus + Grafana, centralized log collection via Fluentd or Loki.
• Working with databases (MySQL, PostgreSQL) and Redis in a cluster: StatefulSet, PersistentVolumeClaims.
• Handling background tasks using RabbitMQ or Redis and Kubernetes Jobs/CronJobs.

Why is this book important?

PHP remains one of the most popular web development languages, but it is often considered "unsuitable" for cloud-native architecture. This book debunks that myth by offering proven patterns and ready-made solutions. You will learn to build fault-tolerant, self-healing systems that easily scale under any load — from startup to enterprise solutions.

The book contains numerous practical examples, ready-made Kubernetes manifests, and code templates that can be immediately applied in real projects. Whether you work with Laravel, Symfony, Yii, or any other PHP framework, you will find universal approaches to orchestration here.

After reading, you will be able to confidently design architecture, configure deployment, and manage the lifecycle of PHP applications in Kubernetes, saving resources and increasing service reliability.
