add native arm image

[realies]

currently, it seems like elasticmq-native runs through qemu-x86_64 on arm, could this be made into a native image? it would really benefit laptop development and battery life, since it currently takes about 10-20% cpu with a light polling client

Continuation of #473

[realies]

thanks @micossow, as I mentioned there, there's darwin aarch64 support over at https://github.com/graalvm/graalvm-ce-dev-builds/releases now, could m1 arm native elasticmq-native images be a thing with it?

[micossow]

It's probably doable, but there seem to be some limitations in the sbt plugin we use: https://github.com/sbt/sbt-native-packager
See: #473 (comment)

[micossow]

It should be possible to build such image now, see: sbt/sbt-native-packager#1503
Some changes in build.sbt are probably also necessary.

I tested the image softwaremill/elasticmq-native:1.3.14 on a Graviton AWS server, but it does not work

# docker run softwaremill/elasticmq-native:1.3.14

The executable in the image is in amd64 format

Other files look for aarch64 architecture.

Will this be fixed? or is there a quick way of building this from the repo manually?

[micossow]

If you need docker image locally, you can run sbt "project nativeServer; clean; assembly; graalvm-native-image:packageBin; docker:publishLocal" on your ARM64 system.

To be able to create native docker images as a part of GH workflow, we need either:

• GH Workflow supporting ARM64 systems
• or cross compilation support in GraalVM [native-image] Cross compilation support? oracle/graal#407

GitHub released a MacOS builder which is M1 based.
Could that be used for ARM64 builds?

@diegobfernandez Interesting - if we only use it for releases, it might not be that expensive (hopefully in the order of a couple of dollars)

Hello, I updated build.sbt to use buildx supported image creation, which should create proper native images for both x64 and ARM. Please test if softwaremill/elasticmq-native:1.4.5-RC1 image works on your ARM machines. If yes, I'll create a release next week.

[micossow]

Update: softwaremill/elasticmq-native:1.4.5-RC2 has a fix for UI.

[micossow]

Fixed in https://github.com/softwaremill/elasticmq/releases/tag/v1.4.6
