Hi,
ceph is supposed to be configured by this tripleo-ansible role [1], which
is triggered by tht on external_deploy_steps [2].
In theory adding [3] should just work, assuming you customize the ceph
cluster mon ip addresses, fsid and a few other related variables.
>From your previous email I suspect in your external-ceph.yaml you missed
the TripleO resource OS::TripleO::Services::CephExternal:
../deployment/cephadm/ceph-client.yaml
(see [3]).

Thanks,
Francesco
