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 all share the same weakness:
explain how to deal with failed OSD disks in a non-containerized
scenario, how to redeploy the OSD after replacing the disk, then at
the end - how to take the cluster over using cephadm, and as a result,
suddenly the "how to replace a disk and redeploy the OSD" knowledge is
inapplicable.

A containerized environment just makes troubleshooting more difficult,
getting access and retrieving details on Ceph processes isn't as
straightforward as with a non containerized infrastructure. I am still not
convinced that containerizing everything brings any benefits except the
collocation of services.

The shift to containers makes sense, as this is the general direction that
the industry as a whole is taking. I would suggest giving cephadm a try,
it's relatively straight forward and significantly faster for deployments
then ceph-ansible is.

Subject: [ceph-users] ceph-ansible in Pacific and beyond?
Hi,
I caught up with Sage's talk on what to expect in Pacific (
https://www.youtube.com/watch?v=PVtn53MbxTc ) and there was no mention
of ceph-ansible at all.
Is it going to continue to be supported? We use it (and uncontainerised
packages) for all our clusters, so I'd be a bit alarmed if it was going
to go away...
Regards,
Matthew
