GraalVM Native Support

This project has been configured to let you generate either a lightweight container or a native executable. It is also possible to run your tests in a native image.

Lightweight Container with Cloud Native Buildpacks

If you're already familiar with Spring Boot container images support, this is the easiest way to get started. Docker should be installed and configured on your machine prior to creating the image.

To create the image, run the following goal:

$ ./mvnw spring-boot:build-image -Pnative

Then, you can run the app like any other container:

$ docker run --rm -p 8080:8080 classhub:0.0.1-SNAPSHOT

Executable with Native Build Tools

Use this option if you want to explore more options such as running your tests in a native image. The GraalVM native-image compiler should be installed and configured on your machine.

NOTE: GraalVM 22.3+ is required.

To create the executable, run the following goal:

$ ./mvnw native:compile -Pnative

Then, you can run the app as follows:

$ target/classhub

You can also run your existing tests suite in a native image. This is an efficient way to validate the compatibility of your application.

To run your existing tests in a native image, run the following goal:

$ ./mvnw test -PnativeTest

Testcontainers support

This project uses Testcontainers at development time.

Testcontainers has been configured to use the following Docker images:

• postgres:latest

Please review the tags of the used images and set them to the same as you're running in production.
