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. ср, 17 мар. 2021 г. в 22:39, Teoman Onay <tonay@redhat.com>:
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.

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 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.

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
