C# (.NET) and Kubernetes: From Monolith to Microservices

The book "C# (.NET) and Kubernetes" is a practical guide for developers who want to master modern approaches to deploying and managing .NET applications in a container environment. The author, Alexey Petrov, a senior developer with 10 years of experience, shares proven techniques and best practices that will help you transition from a monolithic architecture to scalable microservices.

What is this book about?

The book covers the full lifecycle of working with .NET applications in Kubernetes:

• Containerization Basics — creating Docker images for .NET applications, optimizing size and security.
• Deployment in Kubernetes — configuring Pods, Deployments, Services, and Ingress controllers for .NET services.
• Configuration Management — using ConfigMaps and Secrets to store settings and sensitive data.
• Scaling and Load Balancing — horizontal scaling (HPA), working with StatefulSets, and load distribution.
• CI/CD for .NET — automating build, testing, and deployment using GitHub Actions, Azure DevOps, and Helm charts.
• Monitoring and Logging — integration with Prometheus, Grafana, and the ELK stack for tracking the state of .NET applications.
• Security — configuring RBAC, network policies, and secrets to protect .NET microservices.

Who is this book for?

The book will be useful for:

• C# developers who want to learn Kubernetes and container technologies.
• DevOps engineers working with .NET projects and looking for ways to automate deployment.
• Architects planning a transition from a monolith to a microservices architecture on the .NET platform.
• Team leads who want to implement modern CI/CD and orchestration practices in their teams.

What will the reader learn?

After reading the book, you will be able to:

• Create Docker images for .NET applications and publish them to container registries.
• Configure a Kubernetes cluster for deploying .NET services.
• Automate deployment using Helm charts and GitOps approaches.
• Set up monitoring and logging for .NET microservices.
• Ensure application fault tolerance and scaling.
• Apply security best practices in a container environment.

The book contains numerous practical examples, ready-to-use configurations, and step-by-step instructions. All examples are based on current versions of .NET 8 and Kubernetes 1.28+.

Who is it not suitable for? The book assumes basic knowledge of C# and .NET, as well as an understanding of Docker principles. If you have never worked with containers, it is recommended to first learn the basics of Docker.
