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.

Containerizing and deploying a Spring Boot application using Cloud Code

Let's try to containerize and deploy the Spring Boot application we created in the previous section. To containerize our Spring Boot application, we will use jib-maven-plugin. We've used this many times in previous chapters, so I will skip the setup for it here. We will deploy to a local Minikube cluster using kubectl. Let's learn how to do this:

  1. First, we will need a skaffold.yaml file in the root directory of our project.
  2. You can create an empty file named skaffold.yaml and use the Cloud Code auto-completion feature, as shown in the following screenshot, to generate a working skaffold.yaml file:

  3. Sometimes, a new schema version may be available. Cloud Code is smart enough to detect those changes and will suggest that you upgrade the schema as well, as shown in the following screenshot:
