possible validation error in binding ports?

[cboettig]

I tried to bind a port explicitly to 127.0.0.1, (which I believe can be useful when I'm only accessing the app from the host and want to be sure I'm not exposing it to my network). Unfortunately this seems to throw an error in validation:

Port binding '127.0.0.1:5000:5000' does not not match '[<host>:]<container>'

Thanks Carl - this should be fixed as of 9c402cd (branch develop) now
