Hi openstack CLI wizards, Having flavors without disks, I want volumes to be created from images on the fly that I can boot from. But I don't want to do bookkeeping for these volumes; they should disappear once the server disappears. On the command line with nova, I can do this: nova boot --nic net-name=$MYNET --key-name $MYKEY --flavor $MYFLAVOR \ --block-device "id=$MYIMGIFD,source=image,dest=volume,size=$MYSIZE,shutdown=remove,bootindex=0" $MYNAME I did not find a way to do this with openstack server create. Is there one? Here's what I tried: --image $MYIMGID --boot-from-volume $MYSIZE works, except that there is no way to specify delete_on_termination --block-device-mapping "sda=$MYIMGID:image:$MYSIZE:true" does complain that no --image or --volume have been passed. The option does not appear to be used for bootable volumes. I have seen a BP (merged with Ussuri) that would allow a PUT call to update delete_on_termination, but I don't see it usable with the openstackclient ... https://specs.openstack.org/openstack/nova-specs/specs/ussuri/implemented/de...
