Mosquitto is built from source in Alpine Linux Docker container

There's an ongoing bug when using cgo (which the plugin uses to implement mosquitto's expected plugin interface) on Alpine as it uses muslibc instead of glibc, as referenced in #14.

I mentioned some possible workarounds at #15 (comment), but still haven't tried any of those, so it'd be really helpful if you are willing and have the time to give it a go.

I can't get it working with Alpine, using the suggestion above.
I switched to the 'debian:stable-slim' base image, for now. If I have time, I will give it another try.

Ok, thanks. I don't use docker and don't have the time right now to learn it properly and come up with a decent image, but I'll leave this open for the future.

In case you get it to work or believe that an alternative such as using debian:stable-slim is good enough and you want to contribute with docker related additions just make a PR, or let me know if you'd like me to link to an external repo with instructions on how to run a docker image with mosquitto and the plugin in the documentation.

Hi, @huiser. I tried some workarounds a couple of days ago but couldn't get it to work with Alpine. I had started building another image based on debian:stable-slim but we got robbed at work and hadn't pushed it.

So I intend to rework on it next monday and add it to the repo in a docker directory that would look something like this:

-mosquitto-go-atuh
  -docker
    -auth
      acls
      passwords
  Dockerfile
  mosquitto.conf
  go-auth.conf

That's unless you wish to contribute your debian:stable-slim image. Just let me know if that's the case.

I just added an example based in debian:stable-slim at the docker dir.
As I mentioned earlier and now at the example's readme, any contributions or help is very welcome.
