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.

Chapter 8: Deploying to Kubernetes

In this chapter, we will shift our focus to the Kubernetes hosting mode known as Dapr. First, we will learn how to prepare our sample projects so that they can be deployed in a containerized form, before moving on to preparing Dapr in the Azure Kubernetes Service cluster.

This chapter will help us gain visibility of the production-ready environment for a solution based on Dapr: a Kubernetes cluster.

In this chapter, we will cover the following topics:

  • Setting up Kubernetes
  • Setting up Dapr on Kubernetes
  • Deploying a Dapr application to Kubernetes
  • Exposing Dapr applications to external clients

As developers and architects, we mainly focus on defining and implementing a solution. However, it is equally as important to understand the implications of the deployment options and how these can influence our design choices, as well as impact our overall solution architecture.

Our first objective is to provision the Kubernetes...
