Bug Description


We should deprecate --nic in favor of listing the actual options. This would also mean adding a --network and --port option. This avoiding the key value based --nic option.

We've already had a UX bug for this very issue:

nic option in openstack server create command's syntax is,
--nic <net-id=net-uuid,v4-fixed-ip=ip-addr,v6-fixed-ip=ip-addr,port-id=port-uuid>

It can be given multiple times, to create multiple interfaces in the VM-instance.

And so, if we split it into network-id / port-id options. How the
optional parameters, 'v4-fixed-ip' and 'v6-fixed-ip' can be handled ?

Ex: if we want two nic, first nic, don't have to pass v4-fixed-ip and second one, we have to pass the fixed ip. We couldn't map in this case.

with current command, we can give as below,
--nic net-id=1234 --nic net-id=5678,v4-fixed-ip=

with new implementation, how can we pass the v4-fixed-ip ( to the second network ?,
--network 1234 --network 5678

Please clarify...

Hi Ukesh, I think the goal here is simplification and not necessarily feature parity with the --nic option. To get --nic net-id=5678,v4-fixed-ip=, you would first create the port on the network with the specified fixed IP. Then you pass that port in on the openstack server create command.

Hi there,

since this is still open and the --nic option is still a little bit unhandy, I'd like to address this issue again.

Ukesh is right imho: Simplifying the arguments should not include reducing the functionality.

But if we would use --port and --network instead of --nic, isn't it possible to keep v4-fixed-ip and v6-fixed-ip as optional parameters, but for --port and --network instead of --nic?

With your example:

--network 5678,v4-fixed-ip=

Or is that bad syntax?

Btw: If no one else is working on this right now, I could take over the bug and work on a commit.

    Add --network and --port to server create

    --nic option is quite unhandy. It is better to have
    two seperate options --network and --port to add a
    network to a new server.
