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.

Working with Skaffold container image builders

From Chapter 3, Skaffold – Easy-Peasy Cloud-Native Kubernetes Application Development, we know that Skaffold currently supports the following container image builders:

  • Dockerfile
  • Jib (Maven and Gradle)
  • Bazel
  • Cloud-native Buildpacks
  • Custom scripts
  • kaniko
  • Google Cloud Build

In this section, we will cover these in detail by using them with the Spring Boot application we just built in the previous section. Let's talk about Dockerfile first.

Dockerfile

Docker is the gold standard for creating containers for many years. Even though there are many alternatives to Docker today, but it is still alive and kicking. Docker architecture depends on a daemon process that must be running to service all of your Docker commands. Then there is a Docker CLI that sent the commands to the Docker daemon for execution. The daemon process does what is required to push, pull, run container images, and so...
