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.

Applying Skaffold best practices

In this section, we will learn about Skaffold best practices that you, as a developer, can take advantage of, to either speed up your deployment in the inner or outer development loop or use some flags to make things easier while using Skaffold. Let's begin:

  • While working with multiple microservices applications deployed to Kubernetes, sometimes, it's challenging to create a single skaffold.yaml configuration file for each application. In those common cases, you can create skaffold.yaml scoped for each application, and then run the skaffold dev or run command independently for each application. You can even iterate both the applications together in a single Skaffold session. Let's assume we have a frontend app and a backend app for both of them; your single skaffold.yaml file should look like the following:
    apiVersion: skaffold/v2beta18
    kind: Config
    requires:
    - path: ./front-end-app
    - path: ./backend-app
