Open Stack

Hi Greg,

This parameter has just been added to the CLI and it hasn’t been fully implemented yet. Sorry for the confusion. Here is how I expect this parameter to work:

1. Create from neutron network name:
$ zun run --name ctn-ping --nets network=private …

2. Create from neutron network uuid:
$ zun run --name ctn-ping --nets network=c59455d9-c103-4c05-b28c-a1f5d041d804 …

3. Create from neutron port uuid/name:
$ zun run --name ctn-ping --nets port=<port_name_or_uuid> …

4. Give me a network:
$ zun run --name ctn-ping --nets auto …

For now, please simply ignore this parameter. Zun will find a usable network under your tenant to boot the container.

Best regards,
Hongbin

Subject: [openstack-dev] [zun] "--nets network=..." usage question

What is expected for the “--nets network=...” parameter on zun run or create ?
Is it the network name, the subnet name, the network uuid, the subnet uuid, ... I think I’ve tried them all and none work.

neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
