Strange, I just copied that page on my phone, I’ll try again:
https://docs.ceph.com/en/pacific/cephadm/adoption/
I understand your hesitation, stability is key for a storage service.
But if you familiarize with cephadm it’s a pretty neat tool. I’m
planning to upgrade and adopt our own production cluster soon, and a
few customers are planning to do the same.
I haven’t tried to containerize ceph daemons without cephadm yet, so I
can’t really help with that.

Thanks for the reply!
Also sorry for the double message, I forgot to hit reply to list and
instead replied directly.
Maybe I did something wrong, but that page 404'ed for me.
I'm migrating to dockerized Ceph for all daemons, and the only ones
left are the OSDs which is blocking my upgrade to Pacific. I am
hesitant to use something like cephadm since I don't trust it to
always make the right decisions. I know they've come a long way, but
I've just never had a good experience with a push button tool like
cephadm, kubeadm, etc in the past. The main complication here is
that a tool like that might work for a fresh install, but migrating
an existing cluster to it isn't clear.
Thanks again,
Zach

Hi,
are you also planning to switch to cephadm? In that case you could
just adopt all the daemons [1], I believe docker would also work (I
use it with podman).

I have an existing install of Ceph and I'm trying to migrate to a
dockerized install. I setup the OSDs with LVM activation
originally, but I can't figure out how to get LVM based OSDs
working inside docker. I see in the setup scripts that there is
some limited support for this, but I can't quite wrap my head
around what I'm supposed to do.
Is there some preferred method of migrating to dockerized Ceph?
Hopefully without removing LVM from the OSDs since that would take
a long time to migrate data. Also is LVM based OSDs still a
recommended activation method? I see it in the documentation but
since docker doesn't advertise support for it, it seems like LVM
is not a recommended activation method anymore.
Thanks,
Zach
