Serverless Architectures with Kubernetes

By: Onur Yılmaz, Sathsara Sarathchandra

Overview of this book

Kubernetes has established itself as the standard platform for container management, orchestration, and deployment. By learning Kubernetes, you’ll be able to design your own serverless architecture by implementing the function-as-a-service (FaaS) model. After an accelerated, hands-on overview of the serverless architecture and various Kubernetes concepts, you’ll cover a wide range of real-world development challenges faced by real-world developers, and explore various techniques to overcome them. You’ll learn how to create production-ready Kubernetes clusters and run serverless applications on them. You'll see how Kubernetes platforms and serverless frameworks such as Kubeless, Apache OpenWhisk and OpenFaaS provide the tooling to help you develop serverless applications on Kubernetes. You'll also learn ways to select the appropriate framework for your upcoming project. By the end of this book, you’ll have the skills and confidence to design your own serverless applications using the power and flexibility of Kubernetes.

2. Introduction to Serverless in the Cloud

9. Going Serverless with OpenFaaS

Learning Objectives

By the end of this chapter, you will be able to:

  • Set up the OpenFaaS framework on a Minikube cluster
  • Create, build, deploy, list, invoke, and delete functions with the OpenFaaS CLI
  • Deploy and invoke OpenFaaS functions from the OpenFaaS portal
  • Return an HTML web page from OpenFaaS functions
  • Set up the Prometheus and Grafana dashboards to monitor OpenFaaS functions
  • Configure function autoscaling to adjust the function count based on demand

In this chapter, we aim to set up the OpenFaaS framework on top of a Minikube cluster and study how we can work with OpenFaaS functions, using both the OpenFaaS CLI and OpenFaaS portal. We will also look into features such as observability and autoscaling with OpenFaaS.
