Description Sylvain Bauza 2017-03-13 17:07:58 UTC

The blueprint implementing traits for Placement provides a new library called os-traits that needs to be synchronizing what Placement knows about traits.

Basically, that library provides a list of known traits that Placement can support, and any new capabilities would require a synchronization between the library and the Placement DB.

As a consequence, os-traits becomes a dependency for placement service, and any upgrade of os-traits requires a os-traits sync command that updates the placement DB.

All the deployer impacts are written in :

Comment 1 Rajesh Tailor 2017-09-28 04:51:17 UTC

Created a BZ [1] for adding os-traits library in RDO packages.
[1] https://bugzilla.redhat.com/show_bug.cgi?id=1455901


Since the design has changed, instead of having a separate placement-manage command to sync the traits from os-traits library to placement db,
the change https://review.openstack.org/#/c/469578/ sync os-traits library to placement db, whenever new version of library is released.

Comment 2 Rajesh Tailor 2017-09-28 04:53:22 UTC

This is done, as the python-os-traits module is available in RDO packages and dependency for nova-distgit package was added to use this module in nova.
