Multi-Cloud with GraalVM: Building and Deploying Optimized Applications

This hands-on lab focuses on how to build size-optimized applications using. and how to leverage containerization to optimize the runtime environment. You are going to discover ways to minimize application footprint by taking advantage of different Native Image linking options, and packaging a size-compact application into various containers, focusing on two main strategies: Distroless and static, discussing the trade-offs. Every step is a multistage build using the. for the builder and different containers for the runner. 75-90 mins. Application Developer, DevOps Engineer. Intermediate.

Level Up your Spring Boot Java Application with GraalVM

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, , as part of your CI/CD pipeline. 60 - 75 mins. Application Developer, DevOps Engineer. Intermediate.

GraalVM Native Build Tools - for Maven

Learn how to integrate GraalVM Native Image into your Maven workflow. In this lab you will use the Maven plugin for Native Image building, learn how to run the Java agent to generate reflection configuration with Maven, and how to run your unit tests as a native executable. The learning objective for this lab are: Use the. to build, test, and run a demo application. Use the plugin to run unit tests on your native executable. Use the plugin to create the reflection configuration for your native executable. GraalVM Native Image makes it possible to compile any Java application ahead-of-time into a native executable that starts almost instantaneously, provides peak performance with no warmup, and requires less memory and less CPU. It's perfect for containerized workloads and microservices—which is why it has been embraced by Micronaut, Spring Boot, Helidon, and Quarkus. 45 mins. Application Developer, DevOps Engineer.
