linux/arm64 docker image

[JLSteenwyk]

Hi @nextgenusfs & @hyphaltip,

Could a docker image for arm64 architecture be built? Based on this article, multiple platform architectures can be built using this (or a similar) command:

# Only build
docker build --platform linux/amd64,linux/arm64 -t <image-tag> .
# When you need to push
docker build --platform linux/amd64,linux/arm64 -t <image-tag> --push .

Best,

Jacob
