Hello Kafka developers, We have built a prototype analytics processing pipeline using Kafka and Samza and are working on making it production ready. We are using Docker to containerize Kafka service and one problem we are having is specifying configuration options in properties files, specifically the advertised.host.name property. We can not use the result returned from getCanonicalName() because it is not resolvable and would like to specify it as an environment variable when starting the container, as is recommended in http://12factor.net/config .
Currently there is no option to do it, as I understand. Any thoughts around implementing this? I can submit a patch for it myself, if needed, but I would like to get more input from the current developers before going forward. Lukas
