Multi-platform Fuseki images

[namedgraph]

Version

4.7.0

Feature

The current Dockerfile does not build on my Mac M1, presumably because the eclipse-temurin:${JAVA_VERSION}-alpine base image is not multi-platform.

I was able to build on M1 using the Dockerfile below but it's probably far from optimal.

Can you provide specific error messages you encounter when building on a M1 Mac?

There are definitely eclipse-temurin variants that can be used to build multi-platform images on M1 Mac's because I build such images for my $dayjob

It may simply be a case of updating the target JAVA_VERSION in the Dockerfile?

A quick look on Docker Hub shows that eclipse-temurin:17-alpine was only built for linux/amd64 whereas eclipse-temurin:21-alpine has linux/amd64 and linux/arm/v8 builds available

Seems to build fine with eclipse-temurin:21-alpine and the original Dockerfile :)

Please send in a PR to update the Dockerfile to Java21, and Alpine, that is tested on Mac's.
