As a follow up, I've taken some time to move the roles functions in to tripleo-common[0] and out of tripleoclient[1]. With this, I've also updated the validation patch with a small python script that leverages the tripleo-common work. Of course while writing this email I noticed that tripleo-common also pulls in instack-undercloud[3] like tripleoclient[4] so I'm not sure this is actually an improvement. ¯\_(ツ)_/¯ Thanks, -Alex [0] https://review.openstack.org/#/c/474332/ [1] https://review.openstack.org/#/c/474343/ [2] https://review.openstack.org/#/c/472731/ [3] https://github.com/rdo-packages/tripleo-common-distgit/blob/rpm-master/openstack-tripleo-common.spec#L21 [4] https://github.com/rdo-packages/tripleoclient-distgit/blob/rpm-master/python-tripleoclient.spec#L36 > > Thanks, > -Alex > >> >> Dan >> >>> Instead if you have an update to a role, please update the >>> appropriate >>> roles/*.yaml file.
