gRPC Go for Professionals

Overview of this book

In recent years, the popularity of microservice architecture has surged, bringing forth a new set of requirements. Among these, efficient communication between the different services takes center stage, and that's where gRPC shines. This book will take you through creating gRPC servers and clients in an efficient, secure, and scalable way. However, communication is just one aspect of microservices, so this book goes beyond that to show you how to deploy your application on Kubernetes and configure other tools that are needed for making your application more resilient. With these tools at your disposal, you’ll be ready to get started with using gRPC in a microservice architecture. In gRPC Go for Professionals, you'll explore core concepts such as message transmission and the role of Protobuf in serialization and deserialization. Through a step-by-step implementation of a TODO list API, you’ll see the different features of gRPC in action. You’ll then learn different approaches for testing your services and debugging your API endpoints. Finally, you’ll get to grips with deploying the application services via Docker images and Kubernetes.

Prerequisites

You can find the code for this chapter at https://github.com/PacktPublishing/gRPC-Go-for-Professionals/tree/main/chapter3. During this chapter, I will be using protoc to generate Go code out of .proto files. This means that you need to make sure you have protoc installed. You can download a zip file from the Releases page of the Protobuf GitHub repository (https://github.com/protocolbuffers/protobuf/releases); uncompress it and follow the readme.txt instructions (note: we do intend to use Well-Known Types in the future so make sure you also install the includes). On top of protoc, you are going to need two protoc plugins: protoc-gen-go and protoc-gen-go-grpc. The former generates Protobuf code, and the latter generates gRPC code. To add them, you can simply run the following commands:

$ go install google.golang.org/protobuf/cmd/protoc-gen-go
  @latest
$ go install google.golang.org/grpc/cmd/protoc-gen-go-
  grpc@latest

And finally, make sure...
