Building Docker image from spring maven project for arm64 platform

Asked 2022-Mar-24 at 00:10

I'm in a Spring course, and I have a maven application (downloaded from the course resources) built from spring initializr. I can build a local Docker image with mvn spring-boot:build-image (no Dockerfile in the project). By default a Docker image is built as linux/amd64, but I am working with a M1 Apple Silicon chip (arm64). I've been looking many workarounds but with no success. Lastly, I found that maybe adding a Dockerfile and specifying the platform it would build the image accordingly.

My goal is to build a docker image for arm64 architecture.

So, I created a Dockerfile:

ANSWER

Answered 2022-Mar-24 at 00:10

Building an ARM-based image is not currently possible with mvn spring-boot:build-image, because the Cloud Native Buildpacks builders that Spring Boot integrates with do not support this. This is one of the possible items of focus on the Paketo buildpacks 2022 roadmap, which you can cast votes for.

CNB documents a work-around for this, but it's not simple to set up and run.

RUN mvn -f /home/path_to_app/pom.xml spring-boot:build-image -DskipTests

You would need Docker-in-Docker to make something like this work, since the CNB builder processes that would run inside the Docker container need to talk to the Docker daemon. Regardless, this would not allow you to build an ARM image for the reasons stated above.

Answered 2022-Feb-27 at 18:25

Luis Miguel Mejía Suárez's comment worked perfectly and was the easier approach.

In the context of this project, all I had to do was:

Append -SNAPSHOT to the version in /version.sbt (should not be needed normally but for this project I had to do this)
Run sbt publishLocal in the parent project.

After this, the example project (which already targets the -SNAPSHOT version) is able to pick up the locally built package.

UPDATE: (module-info.java)

Per your comment, your original setup used JDK 9+ modules. That's a complex and confusing topic. It would be easiest to simply remove module-info.java and not use modules. If you intend to use modules and keep resources in a separate directory (module), there are multiple options with no one clear choice. Perhaps the easiest option would be to open the "package" containing the resource. Something like this worked in my local test:
