When I try to run docker images of marathon-lb, the PORTS environment var has no effect. Service port mapped to port 10001 by default, I dont't know where the environment variable PORTS is consumed when using docker images to run marathon-lb service.

I can confirm this behaviour. It seems that the value of PORTS (if present) is just printed to stdout during startup but does not override the default (9090).
