I assume you're using Wallaby.
There's a downstream job testing external ceph daily. The external ceph
feature of TripleO in Wallaby is stable. I think you have something else
going on that conflates with your use of external ceph.

External Ceph is already configured before step 4. You can inspect your
system after this failure to see that this role:
https://github.com/openstack/tripleo-ansible/tree/master/tripleo_ansible/roles/tripleo_ceph_client
has done its job of distributing cephx keys and a ceph.conf file into this
path:
https://github.com/openstack/tripleo-heat-templates/blob/stable/wallaby/deployment/cephadm/ceph-client.yaml#L61
That should be all that doing a "-e
/usr/share/openstack-tripleo-heat-templates/environments/external-ceph.yaml"
results in. Maybe there's something else in
my-additional-ceph-settings.yaml that shouldn't be there that's causing
your overcloud to try to create an endpoint? I think that unlikely but I'm
trying to come up with an explanation for the correlation you're reporting.

The above is happening from this role:
https://github.com/openstack/tripleo-ansible/blob/e9cc12d4ce0b1c9e96b58f6102e8a3906ed9a1d3/tripleo_ansible/roles/tripleo_keystone_resources/tasks/admin.yml#L81-L87
To revalidate the case, I tried a fresh setup and saw that deployment again

I really don't think this is related to external ceph configuration.
Correlation does not always mean causality.
any inputs would be helpful

Also, please re-arrange the order of your templates.
Any path with /usr/share should be first. Then any path in /home should
then follow.
openstack overcloud deploy --templates \
-r /home/stack/templates/roles_data.yaml \
-n /home/stack/templates/custom_network_data.yaml \
-e
/usr/share/openstack-tripleo-heat-templates/environments/services/ironic-conductor.yaml
\
<other /usr/share paths>
-e /home/stack/templates/overcloud-baremetal-deployed.yaml \
<other templates in /home/stack>
You override the values in the templates tripleo ships (in /usr/share) with
your own values for your env (in /home/stack).
If you include /usr/share after, then you could override your own custom
values. Just a best practice to rule out other issues.
At this point I think you should find out what command is being executed
when this task runs:
https://github.com/openstack/tripleo-ansible/blob/e9cc12d4ce0b1c9e96b58f6102e8a3906ed9a1d3/tripleo_ansible/roles/tripleo_keystone_resources/tasks/admin.yml#L81-L87
Find out the values. Then run that command manually on the CLI of the
system where it is failing. At that point you'll have decoupled what the
deployment tool is doing vs the failing command on your system and share
that on the list.

I recommend instead that you not modify
/usr/share/openstack-tripleo-heat-templates/environments/external-ceph.yaml
and instead include it and then after it that you override your own values.
