Add port from environment variable #18

Closed stellarpower closed 3 years ago

Nice tiny image! In my podman setup I need to be able to assign each a different port, so this adds the option to run with a PORT environment variable, specifying the internal port to listen on.

ah ok. I'm used to changing ports via port mapping so the EXPOSE can be picked up by other tooling, but I don't have a strong opinion about this

Cheers. :) I am too; Podman containers inside a pod run under the same network host, so they can't share ports and this image did the trick to test my ansible scripts.
