This is one of the approaches to make applications more space efficient and cloud-friendly, introduced in Java 11.

The script _build-jlink.sh_ that runs `docker build` using the _Dockerfile.distroless-java-base.jlink_.
The Dockerfile runs two stages: first it generates a Jlink custom runtime on a full JDK (`container-registry.oracle.com/graalvm/jdk:24`); then copies the runtime image folder along with static website pages into a Distroless Java base image, and sets the entrypoint.
The Dockerfile runs two stages: first it generates a Jlink custom runtime on a full JDK (`container-registry.oracle.com/graalvm/jdk:24`); then copies the runtime image folder along with static website pages into a distroless Java base image, and sets the entrypoint.
Distroless Java base image provides `glibc` and other libraries needed by the JDK, but not a full-blown JDK.

The application does not have to be modular, but you need to figure out which modules the application depends on to be able to `jlink` it.
