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.

Exploring Skaffold container image deployers

In this section, we will look at the container image deployment methods supported by Skaffold. With Skaffold, you can deploy your application to Kubernetes using the following three tools:

  • Helm
  • kubectl
  • Kustomize

Let's discuss them in detail.

Helm

Helm is the package manager, and charts are the packages for your Kubernetes applications. It allows you to define, install, and update your Kubernetes application easily. You can write charts for your applications or use production-ready, pre-packaged charts for popular software such as MySQL and MongoDB from a stable chart repository.

Until Helm 2, Helm followed a client-server architecture. However, due to significant changes being made to the architecture with Helm 3, it is a client-only architecture. Therefore, there is no need to have a server-side component such as Tiller installed on your Kubernetes cluster.

Now, let's learn more about Helm...
