I finally got MQTT Bridge working. It seems the issue was that the Docker container does not accept an alternate port. I tried using first settings,but once I used second container and config options below, I started getting MQTT data from Smartthings.
-p 8001:8001
and
port=8001
-p 8001:8080
and
port=8080
I uncommented the default configurations in the config file and tried sending return messages, however Smartthings does not respond.
