multiarch support for Docker image

[vielmetti]

[work in progress]

Support a Docker image for Zipkin that supports multiple architectures, including arm64.

What I saw

On http://opentracing.io/ there is an instruction on how to use Opentracing that starts

$ docker run -d -p 9411:9411 openzipkin/zipkin

Try this on an arm64 system, try to connect with

curl http://localhost:9411/
curl: (7) Failed to connect to localhost port 9411: Connection refused

Inspect the image and find that it's amd64 only as

root@2a2-neon:~# !611
docker run --rm -it mplatform/mquery openzipkin/zipkin
Image: openzipkin/zipkin
 * Manifest List: No
 * Supports: amd64/linux

What I hoped to see

Multi-architecture zipkin container that pulled a correct arm64/linux version.

What's remaining to see before this issue can be closed

Validation and testing that zipkin indeed runs without issue on arm64/linux.

poking @tianon in case this is an easy fix

I don't know if its possible to build on arm64 with Docker-Hub (I thinks its for some official images, but definitely not with a free-plan). From my understanding the behavior you expect is not possible with the current build infrastructure.
You could build your own docker image on an arm64 system.
