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.

Setting up Dapr on Kubernetes

At this stage, a Kubernetes cluster (specifically, AKS on Azure) is ready to accommodate our workload. We need to install Dapr before we can move on to the preparation phase for our applications.

In Chapter 1, Introducing Dapr, we used the dapr init CLI command to initialize Dapr in our development environment. We’ll use it again here to initialize Dapr in Kubernetes, but we will add the -k parameter:

PS C:\Repos\dapr-samples\chapter09> dapr init -k

Deploying the Dapr control plane to your cluster...
Success! Dapr has been installed to namespace dapr-system.
To verify, run `dapr status -k' in your terminal.
