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.

Deciphering Skaffold's configuration with skaffold.yaml

Any action that Skaffold needs to perform should be clearly defined in the skaffold.yaml configuration file. In this configuration file, you must specify which tool Skaffold has to use to build an image and then deploy it to the Kubernetes cluster. Skaffold typically expects to find the configuration file as skaffold.yaml in the current directory; however, we can override the location using the --filename flag.

Tip

We recommend that you keep the Skaffold configuration file in the root directory of the project.

The configuration file consists of the following main components:

Skaffold also supports a global configuration file, which is located in the ~/.skaffold/config path. The following are the options it supports, which can be defined at the global level:
