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.

Technical requirements

To complete the exercises in this chapter, you will need a VM and the Kubernetes environment. We will continue to use the same environment that we used to learn about Istio and Linkerd.

Check if the keepalived pods are showing READY 1/1 and that their STATUS is Running:

$ kubectl -n keepalived get pods
The keepalived load balancer was installed in Chapter 9, Installing Istio.

To follow the examples in this chapter, you need to clone the scripts from GitHub:

$ cd ~/ # Switch to home directory
$ git clone https://github.com/servicemeshbook/consul.git
$ cd consul
$ git checkout 1.6.1
$ cd scripts
Consul is open source and is maintained at https://github.com/hashicorp/consul. Its home page is https://www.consul.io and is supported by Hashicorp.
