Description

This lab will walk you through the process of building a Spring Boot application, compiling it into a native executable with GraalVM Native Image, and then containerising it. Using a native executable enables you to reduce application startup times, get low resource usage, and generate much smaller containers.

You will also learn how to create a small Distroless container to package your native executable, enabling you to shrink your container images even further.

In this lab you will:

  • Add a basic Spring Boot application to a container image and run it
  • Build a native executable from this application, using GraalVM Native Image
  • Add the native executable to a container image
  • Shrink your application container image size with GraalVM Native Image and Distroless containers
  • See how to use the GraalVM Native Build tools, Maven Plugin , as part of your CI/CD pipeline
