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.

Serverless Plugin for Kubeless

The Serverless Framework is a general framework for deploying serverless applications across different serverless providers. The serverless plugin for Kubeless supports deploying Kubeless functions. Apart from the plugin for Kubeless, the Serverless Framework supports serverless applications such as AWS Lambda, Azure Functions, Google Cloud Functions, Apache OpenWhisk, and Kubeless.

In this section, we will install the serverless framework and create a Kubeless function using the CLI provided by the serverless framework.

Before we start installing the serverless framework, we need to have Node.js version 6.5.0 or later installed as a prerequisite. So, first, let's install Node.js:

$ curl -sL | sudo -E bash -
$ sudo apt-get install nodejs -y

The output is as follows:

Once installed, verify the Node.js version by executing the...
