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 Linkerd

In this chapter, we will install the Linkerd command-line interface (CLI) and then install the control plane. We will install a demo application and inject a Linkerd sidecar proxy after it is connected to show you how to enable a sidecar proxy for existing applications. Then, we will install the nginx ingress controller and create an Ingress route to access this microservice from outside the Kubernetes cluster. We will install Buoyant's booksapp microservice and enable automatic sidecar injection so that proxies get injected while a new application is being installed. Then, we'll create an Ingress rule to route the traffic to the booksapp microservice.

In a nutshell, we will cover the following topics in this chapter:

  • Installing Linkerd's CLI using the latest version
  • Installing the control plane
  • Defining cluster-wide roles and permissions
  • Validating...
