Opening a Socket on a port on OpenShift Python Hosting

Question

I recently started a single gear application, python 2.7 on Openshift.

I am not being allowed to open a socket -

The Terminal Returned with:

File "server.py", line 21, in <module>
    server_socket.bind(("0.0.0.0", PORT))
  File "/opt/rh/python27/root/usr/lib64/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 13] Permission denied

I just need a small socket up and running - does anyone know how I can open a socket on their hosting? If not, what is a good alternative solution so that I can host and open my own python sockets?

Answer 1

you need to bind to your gear's ip address, which on python cartridge i believe is OPENSHIFT_PYTHON_IP, you can't bind to 0.0.0.0, also, only applications bound to port 8080 can be accessed from outside of openshift. (ports 80,443,8000,8443 are all routed to port 8080 on your gear)
