Can I Attach Multiple Ports to an Instance?

Problem

Is it possible to add multiple fixed IP ports to an instance?

Environment

  • Platform9 Managed OpenStack - All versions.
  • Neutron
  • Nova

Answer

  • Openstack allows adding multiple ports to an instance but any ports added after the first one need to be configured manually.
  • The majority of the OpenStack images have only one interface configured by default which is why only the first IP gets configured on the only interface found within the image.

Additional Information

The following blueprint, once implemented, will allow OpenStack to configure secondary interfaces within the instance.
