Solution

Bind for 0.0.0.0:80: unexpected error (Failure EADDRINUSE)

It means that something already exists on your host machine on port 80 what is related to your run command and this flag: -p 80:80 it means that you want to map port 80 from inside container (right part) onto your host machine (left part). Fix for you is to stop some service on port 80 (like Skype - common case on Windows or Nginx/Apache - common case on Linux) or change your mapping to e.g. -p 8080:80 and access your service via localhost:8080
