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.

Section 3: Building and Deploying Cloud-Native Spring Boot Applications with Skaffold

Deploying a Spring Boot application to the GKE

The Spring Boot application that we will use in this section is the same as in the previous chapter (the application we named Breathe – View Real-Time Air Quality Data). We are already familiar with the application, so we will directly jump to the deployment to the GKE. We will be using gke-autopilot-cluster1 we created in the previous section for deployment. We will do the deployment using the following two approaches using Skaffold:

  • Deploying from local to a remote GKE cluster using Skaffold
  • Deploying from Cloud Shell to a GKE cluster using Skaffold

Deploying from local to a remote GKE cluster using Skaffold

In this section, you will learn how you can deploy the Spring Boot application to a remote Kubernetes cluster with the help of Skaffold. Let's begin:

  1. In the previous chapter, we used Dockerfile to containerize our Spring Boot application. However, in this chapter, we will be using the Jib...
