Swift (iOS/macOS) and Kubernetes: Deployment and Orchestration of Mobile Servers

The book "Swift (iOS/macOS) and Kubernetes" is a practical guide for developers who want to master the deployment and orchestration of server-side Swift applications in a Kubernetes environment. Unlike most materials focused on Java or Go, this book is entirely dedicated to the Swift ecosystem: from creating a server-side API on Kitura or Vapor to full-fledged cluster management.

The book is divided into three logical blocks:

• Swift Basics in the Cloud: setting up a server environment, working with Docker containers for Swift (Linux and macOS), creating microservices.
• Kubernetes for the Swift Developer: deploying pods, services, configuring ConfigMap and Secrets, working with Helm charts, managing traffic via Ingress.
• DevOps and Monitoring: CI/CD pipelines for Swift (GitHub Actions + Kubernetes), logging, metrics (Prometheus + Grafana), autoscaling.

Who is this book for?

• iOS/macOS developers transitioning to server-side development with Swift.
• DevOps engineers wanting to learn the specifics of Swift applications.
• Full-stack developers working with Vapor or Kitura.

What you will learn:

• How to package a Swift application into a Docker image smaller than 50 MB.
• How to configure horizontal pod autoscaling based on load.
• How to set up zero-downtime deployment for Swift services.
• How to use SwiftNIO for high-performance networking in Kubernetes.
• How to integrate Kubernetes with Xcode Cloud and TestFlight.

The book contains over 40 practical examples, ready-to-use YAML manifests, and Helm templates. All examples were tested on Kubernetes 1.28+ and Swift 5.9+.

Whether you are developing a backend for a mobile application or creating a cloud service in Swift, this guide will be your navigator in the world of cloud orchestration.
