Linkerd on Kubernetes

Understand how to use service mesh architecture to efficiently manage and protect cloud native microservices of examples that cover security, observability, reliability, and traffic control

Key Features

Learn how to use Linkerd effectively and efficiently in Kubernetes
Increase the reliability and deployment of microservices within Linkerd
Learn Linkerd architecture and how it works and setting it up in your Kubernetes cluster

Book DescriptionWith the growth of containers, kubernetes, and microservices, understanding of Linkerd has become a necessity. This book will give you a solid understanding of how service mesh eases operational management and handles the east-to-west traffic of API calls with microservice in the kubernetes cluster with hands-on examples.

This book starts with service mesh fundamentals: what is a service and how does it work. Next, you will learn what makes Linkerd unique, its architecture, and the specific protocol it uses. It will detail the usage of the control and data planes as well as sidecar proxies. With these concepts in place, you will be ready to deploy Linkerd into Kubernetes and deploy services into the service mesh. Further, you will also learn how to use Linkerd to secure your services with zero trust networking, add observability, increase reliability, and control network traffic. The book aims to provide a step-by-step guide to using Linkerd. You will discover each concept is provided in a logical, organized manner that builds on the previously covered one. With an active opensource project, this book cannot cover all possible advanced use cases but focuses on the core architecture and components.

By end of this book, you will be familiar with Linkerd's capabilities and deploy it into any Kubernetes environment.

What you will learn

Deep dive into Linkerd architecture along with the different components
Get Linkerd up and running in a k3d and minikube cluster
Add microservices with zero downtime into Linkerd with hands-on examples
Learn to inject annotations into microservice deployment manifests
