Serverless Architectures with Kubernetes

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 first described the origins and characteristics of Kubernetes. Following that, we studied the Kubernetes design and components with the details of master and node components. Then, we installed a local single-node Kubernetes cluster and checked the Kubernetes components. Following the cluster setup, we studied the official Kubernetes client tool, kubectl, which is used to connect to a cluster. We also saw how kubectl is used to manage clusters and the life cycle of applications. Finally, we discussed the fundamental Kubernetes resources for serverless applications, including pods, deployments, and StatefulSets. In addition to that, we also studied how to connect applications in a cluster using services. Kubernetes resources for one-time and automated tasks were presented using Jobs and CronJobs. At the end of this chapter, we developed a real-time data collection function using Kubernetes-native resources.

In the next chapter, we will be studying the...
