Should be tripleo_container_manage which is the actual name of the role Reported by: kevin https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.1/html/director_installation_and_usage/managing-containers-with-ansible_preprovisioned#annotations:e791f334-3808-4fcf-91fc-0a797759c1d2
For this doc's version, osp16, `tripleo-container-manage` with hyphens is correct. For osp17 though, it should be underscores `tripleo_container_manage`, as you suggest, so I'll clone this issue for osp17. Thanks for opening the BZ, Naomi
