This is an attempt on building a not so heavy image given the impossibility of using alpine based ones (see iegomez#14, iegomez#15 and iegomez#20).

It uses an intermediate image based on debian:stable-slim to build both mosquitto and the plugin and later on copies the binaries to the final image, also absed in debian:stable-slim, which stands at 113 MB.

The example Dockerfile will also copy conf files present at the current dir as well as set the versions for Go, mosquitto and the plugin. Please change values as needed.

This is just a working example of how a docker image could be built for this project and composed with other images such as a redis one for cache (check docker-compose). Any contributions to make it better are very welcome.
