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.

Activity 1: Twitter Bot Backend for Bike Points in London


Execute the following steps to complete this activity:

  1. Create a main.go file for registering function handlers, as in Exercise 1.

    This code is the entry point of the application where functions are registered, and the main application is started:

    package main
    import (
    func main() {
       fmt.Println("Starting the 🚲 finder..")
       http.HandleFunc("/", FindBikes)
       fmt.Println("Function handlers are registered.")
       http.ListenAndServe(":8080", nil)
  2. Create a function.go file for the FindBikes function:
    func FindBikes(w http.ResponseWriter, r *http.Request) {
       // Get bike points for the query
       bikePoints, err := httpClient.Get(fmt.Sprintf...
