Provide armv6 docker image

[pcarranza]

So this can be executed on a RPI or a pi k8s cluster

I've never built anything but amd64/linux docker images. We may look into this in the future ...

[pcarranza]

I have an image built locally, I can send you a PR to check it out, it's a bit messy but can be useful as a sample.

Still, for releasing purposes and such, have you considered using goreleaser?

[metalmatze]

Nice! Yes, goreleaser is pretty awesome. I would be fine with using it. 😊

[jlsjonas]

Any progress on using goreleaser? docker feels overkill for a go library imho 😅
If help wanted also applies to it; maybe it should be a separate issue // title should be renamed?

[pcarranza]

I completely forgot about this, gimme 5m

[pcarranza]

Here you are #9

I've been running this in a k8s since.... months ago... I just forgot about it because it's been quite stable 😂

[pcarranza]

Looks like there's a hard limitation in Travis: #9 (comment)

WDYT makes sense? I could just skip the whole building docker images to move forward.

[pcarranza]

Well, there you go.

I removed snapshotting with goreleaser in the CI run because it fails to run in travis, so it goes back to run everything vetting, checks, etc, then build with go, but there's 2 more actions in the makefile: snapshot and release.

So, to release you should just tag with something semver correct, and then just run make release
