Dear All,

I have just installed Zun and tried creating a container following the instructions as per the following webpage:

I am getting following error while starting my test container using 'openstack appcontainer run --name container2 --net network=$NET_ID cirros ping':

status_reason     | Docker internal error: 500 Server Error: Internal Server Error ("IpamDriver.RequestAddress: Requested ip address {'subnet_id': u'e684a17b-6b17-4ea2-bbc9-752a21304dcc', 'ip_address': u''} already belongs to a bound Neutron port: f0d6153a-7408-4cd5-82c3-9abed48ad056").

The network I selected is a flat network on openstack with external flag true.

Please advise me how to solve the issue or if there is a specific requirement for this.

Thank you,
Kind Regards,
