Effortless Cloud-Native App Development Using Skaffold

By: Ashish Choudhary

Overview of this book

Kubernetes has become the de facto standard for container orchestration, drastically improving how we deploy and manage cloud-native apps. Although it has simplified the lives of support professionals, we cannot say the same for developers who need to be equipped with better tools to increase productivity. An automated workflow that solves a wide variety of problems that every developer faces can make all the difference! Enter Skaffold – a command-line tool that automates the build, push, and deploy steps for Kubernetes applications. This book is divided into three parts, starting with common challenges encountered by developers in building apps with Kubernetes. The second part covers Skaffold features, its architecture, supported container image builders, and more. In the last part, you'll focus on practical implementation, learning how to deploy Spring Boot apps to cloud platforms such as Google Cloud Platform (GCP) using Skaffold. You'll also create CI/CD pipelines for your cloud-native apps with Skaffold. Although the examples covered in this book are written in Java and Spring Boot, the techniques can be applied to apps built using other technologies too. By the end of this Skaffold book, you'll develop skills that will help accelerate your inner development loop and be able to build and deploy your apps to the Kubernetes cluster with Skaffold.

Building and deploying a Spring Boot application with Skaffold

To understand Skaffold commands and concepts better, in this section, we will build and deploy a Spring Boot Java application to a local single-node Kubernetes cluster using Skaffold.

Note

Whenever we talk about the Kubernetes cluster for local development in this book, we refer to the Kubernetes cluster with Docker Desktop, if not specified otherwise. However, Docker Desktop or minikube is not the only tool available today for running a local Kubernetes cluster. Skaffold also supports Kind https://github.com/kubernetes-sigs/kind and k3d https://github.com/rancher/k3d as target Kubernetes clusters for local development.

Since this will be a sneak-peek of Skaffold, we will not cover everything in detail about Skaffold, as we are going to cover this in the upcoming chapters. I will, however, try to explain the commands used so that you can understand the exact flow. Before we dive into Skaffold, let's first...
