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.

Performing pre-installation tasks

Before we move on to the installation of Istio, there are a few pre-installation tasks that we need to carry out. These include downloading the source code and validating the environment. We will learn how to carry out these tasks in this section.

Downloading the source code

We will be installing Istio in the istio-system namespace and will grant a cluster-admin role to it. This is just for convenience purposes and is not a requirement. The granular permissions, as per the Kubernetes administrator, can be applied to the required namespace for you to install Istio in your actual production environment.

You can download a specific version of Istio from https://github.com/istio/istio/releases...
