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.

Other Kubernetes serverless frameworks

AWS Lambda functions made serverless functions in the cloud very popular. Kubernetes is not a fully-fledged serverless function primitive, but it gets pretty close with the Job and CronJob resources. In addition to this, a plethora of serverless function solutions were developed by the community (Nuclio being one of them). Here are some of the more popular and mature options that we will see in the following subsections:

  • Kubernetes Jobs and CronJobs
  • KNative
  • Fission
  • Kubeless
  • OpenFaas

Kubernetes Jobs and CronJobs

Kubernetes deployments and services are all about creating a set of long-running pods that are supposed to run indefinitely. A Kubernetes Job is all about running one or more...
