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


In this chapter, we learned how to deploy a single-node Kubernetes cluster with Minikube. Then, we installed the Kubeless framework, Kubeless CLI, and Kubeless UI on top of our Minikube cluster. Once the Kubernetes cluster and Kubeless framework were ready, we created our first Kubeless function with Python and deployed it to Kubeless. Then, we discussed multiple ways of invoking Kubeless functions, namely with the Kubeless CLI, the Kubeless UI, HTTP triggers, scheduled triggers, and PubSub triggers. Next, we discussed how to debug common error scenarios that we encounter while deploying Kubeless functions. Then, we discussed how we can use the serverless framework to deploy a Kubeless function. Finally, in the activity, we learned how we can use a Kubeless function to send messages to a Slack channel.

In the next chapter, we shall introduce OpenWhisk, and cover OpenWhisk actions and triggers.
