Help with Freeradius/freeradius-server Docker Container

[Reuben Fischman]

I'm attempting to run the freeradius/freeradius-server:latest docker container on top of Ubuntu 18.04.  Whenever I execute the docker run example shown on the docker hub, the container seems to start and then immediately quit.  Trying to pull log information using docker logs doesn't show anything (empty set is returned)

Any help is appreciated!
