Provide Alpine images for Arm

[oleg-nenashev]

Proposal

Currently we use the Temurin images that do not have Arm platforms implementations for Alpine. It would be nice to add support for Arm Alpine by using a different base image in the Arm configuration

#5 [linux/arm64 internal] load metadata for docker.io/library/eclipse-temurin:11.0.21_9-jre-alpine
#5 ERROR: no match for platform in manifest: not found

#2 [linux/arm/v7 internal] load metadata for docker.io/library/eclipse-temurin:11.0.21_9-jre-alpine
#2 ERROR: no match for platform in manifest: not found

temurin alpine does support arm64, if using Java 21. Is this an option?

is there any update on this? Would be a very welcome feature.

Alpine provides OpenJDK builds out of the box as well:

• x86_64 https://pkgs.alpinelinux.org/package/edge/community/x86_64/openjdk21
• aarch64 https://pkgs.alpinelinux.org/package/edge/community/aarch64/openjdk21

I just came to raise this issue!

I think we should either:

• add support for multi-arch Alpine images
• modify "Supported Architectures" to note that this is only true for the non-Alpine image

++ that working with upstream Eclipse Temurin to get multi-arch image support for the JRE 11 Alpine images would be great
