Errors for nginx volumes in deployment demo

[hubitor]

I'm trying to replicate the deployment demo setup from here:

http://docs.pyspider.org/en/latest/Deployment-demo.pyspider.org/ but I'm getting these errors at the nginx volumes lines:

Starting pyspider_nginx_1 ... error

I've tried several things but I still don't know what I'm doing wrong. How can I set the volumes up?
