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.

What does Istio bring to the table?

Istio is a service mesh that was originally developed by Google, IBM, and Lyft. It was introduced in mid-2017 and took off like a rocket. It brings a coherent model with a control and data plane, is built around the Envoy proxy, has a lot of momentum, and already serves as the foundation for additional projects. It is, of course, open source and a Cloud Native Computing Foundation (CNCF) project. In Kubernetes, each Envoy proxy is injected as a sidecar container to each pod that participates in the mesh.

Let's explore the Istio architecture, and then dive into the services that it provides.
