I too would be amenable to a cephadm orchestrator on bare metal if that were an
option.
I thought that I would drop this video for anyone that hasn't seen it yet.
It hits on a lot of people's sentiments about containers being not great for

Cephadm with a no containers option would do.

Hi all,

I vote for an SSH orchestrator for a bare metal installation too!
(And no, I'm not able to write it.)
Our second Ceph cluster is underway, and I don't know if we ever update our
first cluster (nautilus) to a containerized version. It is constructed a
special way.
Thanks!

I agree with this sentiment.
Please do not make a containerized and orchestrated deployment
mandatory until all of the documentation is rewritten to take this
deployment scenario into account.
Also, in the past year, I have personally tested three Ceph training
courses from various vendors. They

Is there even a benefit? We as croit collocate all our services from Ceph

There should not be any performance difference between an un-containerized
version and a containerized one.
The shift to containers makes sense, as this is the general direction that the

relatively straight forward and
Hi!
AFAIK the focus is on ceph-adm to replace ceph-ansible. Today it is still
missing some important features but it is just a matter of time. I don't

ceph-ansible but if someone feels the need to keep it working and
