dockergen binary support for alpinelinux

[hmalphettes]

Hi, I am curious if there is some interest in preparing a binary that works with Alpine Linux?

I built such binary following the same pattern than what @lorenz outlined for forego here:
ddollar/forego#65 (comment)

My Alpine based image of nginx-proxy weighs 23MB

Such a binary works also on glibc Linux distros; I have not tested that for a fact but if that helps here are my forego and dockergen binaries for x64: https://github.com/hmalphettes/nginx-proxy/releases/tag/0.0.0

Thanks for your attention.

I have tested it, they work just fine as long as you don't use NSS (nobody uses that inside Docker).

@lorenz What do you mean about NSS? docker-gen uses Go's crypto/tls library for TLS support.

[lorenz]

Sorry, meant nsswitch

@lorenz Got it.

That being said, the docker-gen binary is not only used inside Docker.
