Single node ceph

Is single node ceph supported in production?
Not supported but works obviously. I've set it up a few months ago to play around with it. From a technical standpoint it works, yet not from a conceptionally one. Without a cluster it's kind a useless. Just virtualize 3 (or better 5) nodes and do a proper ceph setup to play around with.

I am curious: what would be your use case?

Teaching/Learning? Or are you looking for the storage type that fits your needs? Some hints: https://pve.proxmox.com/pve-docs/chapter-pvesm.html#_storage_types
Someone suggested it for software RAID on 3 standalone systems but I think Ceph (multinode cluster) or ZFS (since that is what it is designed for) would be better options. I sometimes use the 'is it supported in production' question to short circuit the debate.

So..., ZFS then!
