I think the primary goal of a container environments are resource isolation. At least when
I read about the history I never read anything about a tool for people to skip to learn
something.
But you clearly portray the situation here. Nobody here is against container environment,
because every tool has its purpose. But the container solution proposed here is not for
the purpose of utilizing container benefits, but for creating a tool so 'I do not know
what to do' people can use ceph. And because this is the development perspective and
ceph is not really adapted for being used in containers, you get the current friction with
accepting cephadm.
Eg. this command is wrong in my opinion
ceph orch device ls
What has a device list to do with having an OC or not?
I do not even know why ceph is working on something that uses Kubernetes, let the
Kubernetes platform implement a ceph solution. If ceph wants be used in a container
environment, start making the daemons ready to run in container environments.
So my question still stands: What problem is it actually that the cephadm dev team is
trying to solve? That is not clear to me.

Because all of this reads way to negative regarding containers for me I
wanted to give a different perspective.
Coming from a day to day job, that heavily utilizes kubernetes for its
normal environment, I found cephadm quite like a godsent,
instead of having to deal with a lot of pesky details with installations
and services, having to learn ansible or ceph-deploy, that tool did like
90% of everything in a way I already feel familiar with it.
Additionally, having some pools for not so important data using low
replications counts, it is quite nice, that cephadm only concurrently
upgrades osd's in matter that no service interruptions happen.
There are still some shortcomings (eg. some limitations when moving osd
devices between hosts), but as it is still a relatively new tool that is
to be expected.
