Native ARM64 support

[j03k64]

I assume you have access to push multiple architecture builds for the same image. I was able to confirm that building on ARM64 works fine on my M1 Mac. I was wondering if was possible to push an ARM64 architecture tag so that this can run without emulation on ARM-based machines.

Using the Dockerfile from the 1.1.20 release:

/usr/local/bin $ cat /etc/os-release

Do you know how can I do that without access to a Mac?

[j03k64]

Hey @sevein I've used docker buildx in the past with success: https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/

I forked your repo (which I don't want to maintain long term, but used it as a proof of concept for you) on an x86 machine I did (after installing buildx plugin):

docker login
cd 1.1.20/

docker buildx build -t shootproof/docker-gearmand:latest --platform linux/arm64,linux/amd64 --push .

You can see the multiple tags here: https://hub.docker.com/r/shootproof/docker-gearmand/tags

You'll need to obviously update the -t argument to artefactual/gearmand.

I think it worked! I didn't know that buildkit had qemu emulation support, that's amazing. I've published a new image with the latest version of alpine and gearman 1.1.21.

Thank you so much! It looks like it's working as expected!

I've deleted my fork.

Don't forget to update the latest tag and the README.md file :-)

[sevein]

Thanks, just pushed latest.
