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

We will go through the Istio install process using three different methods:

  • Install using the helm template to generate the YAML file
  • Install using helm and tiller
  • Install through a demo profile using the kubectl apply command

Installing Istio using the helm template

Helm is a package manager that gives options to install a software package using either a URI, TGZ file, or a directory. Since we downloaded Istio from GitHub, we will use the directory as an input to the helm command.

If using the helm template command, we need to make sure that we create a Custom Resource Definition (CRD) first:

  1. Create the istio-system namespace, which will be used by Istio:
$ kubectl create namespace istio-system
namespace...
