Copyright © 2023, Oracle and/or its affiliates Why GraalVM Native Image? 4 23/11/2023 Compile a Java application ahead-of-time into a native executable so that it starts almost instantaneously, provides peak performance with no warmup, and requires less memory and CPU resources Perfect for containerized workloads and microservices Adopted by Micronaut, Spring Boot, Helidon, and Quarkus IDE and Java Tools Use your favourite Java IDE and development tools Develop Build Native Build Tools Use Maven and Gradle plugins that make it easy to compile your applications ahead- of-time as part of a build process Test JUnit 5 Support Test your native applications with JUnit test support compiled ahead-of-time Debug Debugging with GDB Set breakpoints, step through Java sources line-by-line, and inspect variables in a native executable with GDB and in supported IDEs Support for JFR, JMX, and more Monitor with the same JVM tools such as JFR, JMX, heap dumps, jvmstat Monitor Container Images Deploy in light-weight container images. A statically-linked native executable can even run in a scratch container image Package & Deploy
- 5. Demo Part Objectives 1. Add a basic Spring Boot application to a container image and run it 2. Build a native executable from this application, using GraalVM Native Image 3. Add that native executable to a container image 4. Shrink the application container image size using Distroless containers 5. See how to use the GraalVM Native Build tools, Maven Plugin in particular 6. Use GitHub Actions to automate the build of a native executable as part of a CI/CD pipeline 5 Copyright © 2023, Oracle and/or its affiliates
