Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

Overview of this book

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment. You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability. By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

Installing Istio

So far, in this section of this book, we have learned about control and data plane concepts. We then deployed the demo application for Istio in our Kubernetes environment. In this chapter, we will go through the three installation methods of Istio and enable the demo application to use Istio through automatic sidecar injection. We will then show both the automatic and manual ways of injecting a sidecar in to each microservice for the Bookinfo demo application.

The package installation procedure in Kubernetes is going through a transformation—starting with Helm (the client) and Tiller (the server) and then the operator-based install. At the time of writing, the Istio operator based-install is evolving. We will focus on helm install and you will learn about the pre-packaged Istio profile-based installation.

In a nutshell, we will be carrying out the following...
