Hands-On Microservices with Kubernetes

By: Gigi Sayfan

Overview of this book

Kubernetes is among the most popular open source platforms for automating the deployment, scaling, and operations of application containers across clusters of hosts, providing a container-centric infrastructure. Hands-On Microservices with Kubernetes starts by providing you with in-depth insights into the synergy between Kubernetes and microservices. You will learn how to use Delinkcious, which will serve as a live lab throughout the book to help you understand microservices and Kubernetes concepts in the context of a real-world application. Next, you will get up to speed with setting up a CI/CD pipeline and configuring microservices using Kubernetes ConfigMaps. As you cover later chapters, you will gain hands-on experience in securing microservices and implementing REST, gRPC APIs, and a Delinkcious data store. In addition to this, you’ll explore the Nuclio project, run a serverless task on Kubernetes, and manage and implement data-intensive tests. Toward the concluding chapters, you’ll deploy microservices on Kubernetes and learn to maintain a well-monitored system. Finally, you’ll discover the importance of service meshes and how to incorporate Istio into the Delinkcious cluster. By the end of this book, you’ll have gained the skills you need to implement microservices on Kubernetes with the help of effective tools and best practices.

Serverless link checking with Nuclio

Before we dive into LinkManager and close the loop of link checking in Delinkcious, let's get familiar with Nuclio (https://nuclio.io/) and explore how it provides a serverless function solution that works very well for Delinkcious.

A quick introduction to Nuclio

Nuclio is a polished, open source platform for high-performance serverless functions. It was developed by Iguazio and supports multiple platforms, such as Docker, Kubernetes, GKE, and Iguazio itself. We obviously care about Kubernetes, but it's interesting to note that Nuclio can be used on other platforms too. It has the following features:

  • It can build functions from the source code or provide your own container.
  • It...
