Docker port 80 bind error

Question

Hello everyone! 

I am hoping someone could give me a hint what could be wrong with the above. I am trying to run a simple web app with Redis in docker, and upon executing (as root) 'docker-compose up' the Redis container launches, but the app fails with permission denied. however, when the app is launched via docker run [image path] it runs ok (but loses Redis dependency of course). Hoping someone could point me in the right direction about this port 80 bind error. 

Thanks!
