Swift (iOS/macOS) and Kubernetes: Deploying and Orchestrating Mobile Backends

The book "Swift (iOS/macOS) and Kubernetes" is the first practical guide in Russian that connects the world of mobile development in Swift with modern practices for managing containerized applications. If you are an iOS/macOS developer who wants to independently deploy backends for your applications, or a DevOps engineer seeking to understand the specifics of Swift services — this book is for you.

What is this book about?

The book starts with the basics: you will get acquainted with the server-side Swift ecosystem (Vapor, Kitura frameworks) and the basic concepts of containerization. Then, step by step, you will learn how to:

• Containerize Swift applications — create lightweight Docker images for iOS/macOS backends, taking into account the specifics of compilation for different architectures.
• Deploy a Kubernetes cluster — configure local Minikube, cloud solutions (Yandex Cloud, AWS EKS), and manage pods with Swift services.
• Organize CI/CD — automate the build, testing, and deployment of Swift code using GitHub Actions and GitLab CI.
• Scale and monitor — configure horizontal pod autoscaling (HPA), logging (ELK), and metrics (Prometheus + Grafana) for Swift microservices.
• Work with databases — connect PostgreSQL, Redis, and other storage systems to Swift applications in Kubernetes.

Who is this book for?

• iOS/macOS developers who want to master server-side development in Swift and independently deploy backends.
• DevOps engineers interested in the specifics of the Swift ecosystem in the context of Kubernetes.
• Team Leads and architects planning to implement a microservice architecture in Swift.

What will you learn?

• How to build a minimal Docker image for a Swift application (up to 50 MB in size).
• How to configure an Ingress controller for routing traffic to Swift services.
• How to manage secrets and configurations (ConfigMaps, Secrets) in Kubernetes.
• How to organize zero-downtime deployment for mobile backends.
• How to write Helm charts for Swift projects.

The book contains many ready-made code examples, Dockerfile files, and Kubernetes manifests that can be adapted for your projects. All examples have been tested on current versions of Swift 5.9+, Docker 24+, and Kubernetes 1.28+.

Note: Reading the book requires a basic knowledge of Swift and a general understanding of what containers are. Experience with Kubernetes is not required — all concepts are explained from scratch.
