Docker example failure to start.

I'm having an issue testing Goddd demo app, after watching presentation https://www.youtube.com/watch?v=twcDf_Y2gXY.

Any idea what can possibly be the issue? Thanks in advance for your time.

Changing port 8080 -e ROUTINGSERVICE_URL=http://pathfinder:8080 to -e ROUTINGSERVICE_URL=http://pathfinder:7878 still have the same result.
