Practical Microservices with Dapr and .NET

By: Davide Bedin

Overview of this book

Over the last decade, there has been a huge shift from heavily coded monolithic applications to finer, self-contained microservices. Dapr is a new, open source project by Microsoft that provides proven techniques and best practices for developing modern applications. It offers platform-agnostic features for running your applications on public cloud, on-premises, and even on edge devices. This book will help you get to grips with microservice architectures and how to manage application complexities with Dapr in no time. You'll understand how Dapr offers ease of implementation while allowing you to work with multiple languages and platforms. You'll also understand how Dapr's runtime, services, building blocks, and software development kits (SDKs) help you to simplify the creation of resilient and portable microservices. Dapr provides an event-driven runtime that supports the essential features you need to build microservices, including service invocation, state management, and publish/subscribe messaging. You'll explore all of those in addition to various other advanced features with this practical guide to learning Dapr. By the end of this book, you'll be able to write microservices easily using your choice of language or framework by implementing industry best practices to solve problems related to distributed systems.

Deploying a Dapr application to Kubernetes

The service code for our Dapr application is now complete. However, we must package it so that it can be deployed to Kubernetes in a suitable manner. Our first objective is to publish these services as Docker containers.

The sample that’s available for this chapter, C:\Repos\dapr-samples\chapter08, is aligned with the status we reached at the end of Chapter 7, Using Actors. To recap, the following are the Dapr applications that comprise our overall solution:

  • sample.microservice.order
  • sample.microservice.reservation.service
  • sample.microservice.reservationactor.service
  • sample.microservice.customization
  • sample.microservice.shipping

There are other projects in this chapter’s folder. However, the previous list only represents the Dapr applications that need to be built as Docker images, which, for simplicity, are contained in separate folders with the same names and with matching .proj ASP.NET project...
