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.

Alternatives to Istio

Istio has a lot of momentum, but it's not necessarily the best service mesh for you. Let's take a look at some other service meshes and consider their attributes.

Linkerd 2.0

Buoyant is the company that coined the term Service Mesh in 2016 and came out with the first service mesh – Linkerd. It was based on Twitter's Finagle and was implemented in Scala. Since then, Buoyant developed a new service mesh that focused on Kubernetes, called Conduit (which was implemented in Rust and Go), and later (in July 2018) renamed it to Linkerd 2.0. It is a CNCF project like Istio. Linkerd 2.0 also uses sidecar containers that can be automatically or manually injected.

Due to its lightweight design...
