Hello list, In order to standardize the way sync_db is done across modules, I would like to offer a suite of patch[1] that enforces a common pattern. Pattern is : if $sync_db { include COMPONENT::db::sync } class COMPONENT::db::sync { openstacklib::db::sync { [...] } } The openstacklib::db::sync[2] is currently only a wrapper around an exec that does the actual db sync, this allow to make any modification to the exec into a single place. The main advantage IMO is that a contributor is provided with the same experience as it is not the case today across all modules. Two examples : Keystone : https://github.com/stackforge/puppet-keystone/blob/master/manifests/init.pp#L829-L832 Cinder : https://github.com/stackforge/puppet-cinder/blob/master/manifests/api.pp#L175-L187 and https://github.com/stackforge/puppet-cinder/blob/master/manifests/db/sync.pp I would like to know your thoughts about this idea and your feedbacks. Thank you in advance, [1] https://review.openstack.org/#/q/status:open+branch:master+topic:db_sync,n,z [2] https://review.openstack.org/#/c/185601/ -- Yanis Guenane
