Public bug reported: The metadata definitions in etc/metadefs allow each namespace to be associated with a resource type in OpenStack. Some types of resources have more than one type of properties, so the namespaces allow this to be specified using a properties_target attribute.
For example, cinder supports both "image properties" and "user properties". Image properties affect nova scheduling and are handled by the nova scheduler the same way image properties are. User properties are just plain metadata. Example: https://github.com/openstack/glance/blob/7ba2346795b6cc1c1c061bbe63ae1d62f812a0ca/etc/metadefs /compute-guest-memory-backing.json#L19 There are several metadata definitions for software that are associated with Nova instances (OS::Nova::Instance) which should have their properties target set to "metadata". The ability to add metadata to an instance leveraging these definitions at launch time was recently added to horizon. In a follow up discussion, somebody asked about using the metadata definitions to also choose nova scheduler hints at launch time and how to make sure that the two weren't confused. This raised our awareness that we don't have properties_target set to "metadata" (rather than "scheduler_hints") for OS::Nova::Instance on the following software namespace files: https://github.com/openstack/glance/blob/7ba2346795b6cc1c1c061bbe63ae1d62f812a0ca/etc/metadefs /software-databases.json#L16 https://github.com/openstack/glance/blob/7ba2346795b6cc1c1c061bbe63ae1d62f812a0ca/etc/metadefs/software-runtimes.json#L16 https://github.com/openstack/glance/blob/7ba2346795b6cc1c1c061bbe63ae1d62f812a0ca/etc/metadefs /software-webservers.json#L16 It should be noted that updating namespaces is already possible with glance-manage. E.g. ttripp@ubuntu:/opt/stack/glance$ glance-manage db_load_metadefs etc/metadefs -h usage: glance-manage db_load_metadefs [-h] [path] [merge] [prefer_new] [overwrite] positional arguments: path merge prefer_new overwrite So, you just have to call: ttripp@ubuntu:/opt/stack/glance$ glance-manage db_load_metadefs etc/metadefs true true See also: https://youtu.be/zJpHXdBOoeM ** Affects: glance Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
