Practical Microservices with Dapr and .NET - Second Edition

By: Davide Bedin

Overview of this book

This second edition 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 simplifies development while allowing you to work with multiple languages and platforms. Following a C# sample, you'll understand how Dapr's runtime, 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 for building 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. With a focus on deploying the Dapr sample application to an Azure Kubernetes Service cluster and to the Azure Container Apps serverless platform, you’ll see how to expose the Dapr application with NGINX, YARP, and Azure API Management. By the end of this book, you'll be able to write microservices easily by implementing industry best practices to solve problems related to distributed systems.

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 architects and developers, we usually mainly focus on defining and implementing a solution. However, it is 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 cluster and...
