PHP and Kubernetes: Orchestration and Deployment of Modern Web Applications

The book "PHP and Kubernetes" is a practical guide that merges the world of classic PHP development with modern container orchestration tools. Whether you are a PHP developer looking to take your projects to a new level of fault tolerance and scalability, or a DevOps engineer seeking effective ways to work with legacy code, this book is for you.

What the book is about

The author systematically guides the reader from the basics of containerizing PHP applications to full lifecycle management of services in a Kubernetes cluster. You will learn how to:

• Create lightweight Docker images for PHP (including optimization with Alpine and multi-stage builds).
• Set up a local environment with Minikube or Kind for testing.
• Deploy PHP applications in Kubernetes using Deployment, Service, and Ingress.
• Manage configurations via ConfigMap and Secrets, including handling .env files.
• Ensure persistent data storage (PersistentVolume) for MySQL, Redis, or PHP sessions.
• Scale PHP-FPM horizontally (HPA) and configure load balancing.
• Organize CI/CD pipelines for automatic deployment of PHP projects to Kubernetes.
• Monitor applications with Prometheus and Grafana, and collect logs via Fluentd.

Who it is for

The book is aimed at PHP developers with a basic knowledge of Docker who want to master Kubernetes. It will also be useful for DevOps engineers who need to adapt PHP projects for cloud infrastructure. A solid command of PHP and Linux is sufficient for reading.

What you will learn

• How to properly containerize a monolithic application on Laravel or Symfony.
• Principles of building a microservice architecture in PHP.
• Methods for seamless version updates (Rolling Update) and rollbacks (Rollback).
• How to secure an application using Network Policies and resource limits.
• Real-world cases: from a simple blog to a high-load API.

The book contains many ready-made YAML manifests, Dockerfile examples, and automation scripts. All examples are tested on current versions of PHP 8.x and Kubernetes 1.28+. After reading, you will be able to independently design infrastructure for any PHP project ready for production.

Ideal for those who want to move from "it just works on the server" to "it works reliably in the cloud."
