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 Consul

Consul is very simple to install. It is a single Go binary that acts as a client and as well as a server. You can include Consul by provisioning VMs or bare metal servers. We will use the Consul Helm chart to show the installation process in a Kubernetes environment.

In this chapter, you will learn how to install the Consul agent in a VM and look at the Consul installation procedure in a Kubernetes cluster. The Consul service mesh is very easy to form in a Kubernetes environment using the Consul Connect feature, which enables automatic injection of the sidecar proxy for existing and new applications. However, it is slightly more complex to build the service mesh in a VM or bare-metal environments for Consul.

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

  • Installing Consul in a VM
  • Installing Consul in Kubernetes
