support arm64 architecture

[longquan7]

I want to build this image on arm64 architecture, but I'm not sure that can be support arm64 architecture https://cdn.crate.io/downloads/releases/crate-2.1.5.tar.gz

@longquan7 as crate uses java which is available for arm64 it should work fine.

@seut OK, I was build this image on arm64 architecture and successed ,I use FROM arm64v8/alpine:3.5 to build .So I think it can be support arm64 and can you push it to https://hub.docker.com/u/arm64v8/ ?

I want to konw this image if support arm64 can you add it to the https://hub.docker.com/u/arm64v8/ ?

Since this image is based on Alpine, multi-architecture support in official images will need to wait on gliderlabs/docker-alpine#304.

See https://github.com/docker-library/official-images#architectures-other-than-amd64 and https://github.com/docker-library/official-images#multiple-architectures for more information about multi-architecture official images. 👍
