Bug Description

By using openstackclient, it is possible to add/remove floating IP to/from server:

  usage: openstack server add floating ip [-h] [--fixed-ip-address <ip-address>]
                                        <server> <ip-address>

  usage: openstack server remove floating ip [-h] <server> <ip-address>

It would be nice to have the a similar command for adding/removing floating IP to/from zun container. Possibly, this can be implemented in the Zun OSC plugin https://github.com/openstack/python-zunclient/tree/master/zunclient/osc .

NOTE: nova is deprecating the floating IP endpoints: https://developer.openstack.org/api-ref/compute/#floating-ips-os-floating-ips-deprecated , so zun will follow nova and skip the floating ip support in server side. That said this feature is likely to be a client-side feature.

This bug's title "Support adding/removing floating IPs" made me think that it is impossible for a container to have a floating IP address. Maybe the title should be "Support adding/removing floating IPs by specifying container instead of port".

When searching with google, I could not figure out how to use floating IPs with a simple zun container. I'm an openstack beginner. For the benefit of other beginners, I wanted to show how:

Run: openstack port list

Find which row has your container's private IP address.

Put that row's port id in the following command:

openstack floating ip set <floating IP addr> --port <port id>

Then you can connect from outside openstack to the floating IP address to reach your zun container.
