Athens: Publish Athens server docker image for armv6

[atomi]

Since Athens is using Drone which also offers a plugin to publish manifest files can multi arches be supported?

I was able to build 955929d just fine on a Raspberry Pi 3 with only a tiny change in the Dockerfile

 FROM alpine

Edit: Obviously this is not critical but it would be a nice to have for further updates. Thanks.

So for what it's worth, I've been playing around with Athens on the Pi and it does indeed work but it is pretty slow.

So I'm not sure there will be many takers. 🤔

Is there a reason the Dockerfile doesn't use the alpine tini package directly?

I wasn't aware tini was available in alpine but probably not.
It looks like it's the same version available as well.

I think it's interesting b/c it would potentially enable Athens to run on AWS EC2 A1 or Scaleway ARM servers https://www.scaleway.com/en/arm-instances/

[Kunde21]

I've built athens on arm, arm64, and amd64 with a multiarch manifest here: hub.docker.com/r/kunde21/athens-arm

I'll be testing on my local hardware (rpi3 and odroid XU4), but it would be good to get others to test, too. Main focus for testing is performance on different hardware, so we can give some general recommendations when it's released on the official gomods dockerhub.

[atomi]

By the way, according to the tini README an init is included in docker now by passing --init so I'm not sure tini is even necessary anymore.

Edit: So since docker doesn't make --init default it's probably a good bet to keep it as is. Sorry for the noise.

@atomi no problem!
The reason we have it is #1155

[atomi]

@marpio Thank you!

[arschles]

@atomi @marpio @Kunde21 since we closed #1155 and we stick with running Athens under tini in our images, do you think we can close this?

[atomi]

Apologies. Yes!

[arschles]

No apologies necessary @atomi. Thanks for responding 😁
