Hands-On Microservices with Kubernetes

By: Gigi Sayfan

Overview of this book

Kubernetes is among the most popular open source platforms for automating the deployment, scaling, and operations of application containers across clusters of hosts, providing a container-centric infrastructure. Hands-On Microservices with Kubernetes starts by providing you with in-depth insights into the synergy between Kubernetes and microservices. You will learn how to use Delinkcious, which will serve as a live lab throughout the book to help you understand microservices and Kubernetes concepts in the context of a real-world application. Next, you will get up to speed with setting up a CI/CD pipeline and configuring microservices using Kubernetes ConfigMaps. As you cover later chapters, you will gain hands-on experience in securing microservices and implementing REST, gRPC APIs, and a Delinkcious data store. In addition to this, you’ll explore the Nuclio project, run a serverless task on Kubernetes, and manage and implement data-intensive tests. Toward the concluding chapters, you’ll deploy microservices on Kubernetes and learn to maintain a well-monitored system. Finally, you’ll discover the importance of service meshes and how to incorporate Istio into the Delinkcious cluster. By the end of this book, you’ll have gained the skills you need to implement microservices on Kubernetes with the help of effective tools and best practices.

Summary

In this chapter, we dealt with the very important topic of storage and real-world data persistence. We learned about the Kubernetes storage model, the common storage interface, and StatefulSets. Then, we discussed how to manage relational and non-relational data in Kubernetes and migrated several Delinkcious services to use proper persistent storage through StatefulSets, including how to provide data store endpoints for StatefulSet pods. Finally, we implemented a non-ephemeral data store for the news service using Redis. At this point, you should have a clear idea of how Kubernetes manages storage and is able to choose the proper data stores for your system, as well as integrate them into your Kubernetes cluster and with your services.

In the next chapter, we will explore the exciting domain of serverless computing. We'll consider when the serverless model is useful...
