🏗 GraalVM Maven builder base image

A base image for multi-phase Docker builds targeting native Spring Boot 3.x images running on Alpine on both amd64 and aarch64 architectures.

♻️ This image is the builder image for Java applications in the observabilitystack and ping7io organization

Using the builder

Use this builder image in your Java build stage.

# build stage
FROM ghcr.io/observabilitystack/graalvm-maven-builder:21.0.1-ol9 AS builder
RUN mvn -B native:compile -P native \
    --no-transfer-progress -DskipTests=true && \
    chmod +x /build/target/application

# run stage
FROM debian:bookworm-slim
COPY --from=builder "/build/target/application" /srv/application
CMD exec /srv/application

🏃‍♀️ Picking a runner image

In the example above we used debian:bookworm-slim as runner image. Use any glibc distro with glibc >= 2.34 as a runner image. Examples are:

• Oracle Linux 9
• Debian Bookworm Slim (testing)

☝️ Running on Alpine is not possible yet (see Limitations)

Limitations

This image strives to give you a easy image creation experience on both aarch64 and x86_64 architectures. Unfortunately, building a static executable runnable on Alpine Linux is currently not supported by GraalVM.

📦 Building locally

GRAALVM_TAG=21.0.1-ol9
GRAALVM_TAG=21.0.1-muslib-ol9
docker build \
    -t observabilitystack/graalvm-maven-builder:${GRAALVM_TAG} \
    --build-arg GRAALVM_TAG=${GRAALVM_TAG} .

Future work

As soon as GraalVM supports building static images using musl on arm64, this image will add the capability. Current work can be seen in Dockerfile.musl.
