During CDM on Wednesday I suggested that ceph-daemon should probably be
renamed before octopus (and before the name sticks). In speech "ceph
daemon" is confusing, and the name doesn't really reflect what it
is:
a user-facing tool
- to bootstrap a new cluster,
- launch a (containerized) shell,
- enter an existing daemon container,
- tail a daemon's log, or
- adopt a daemon deployed with a legacy tool (ceph-deploy, ceph-ansible,
etc) into a ceph-daemon style container
- remove all trace of a cluster from the localhost,
and an internal tool used by ssh-orch to
- deploy or remove a container running a ceph daemon
- start, stop, or update an existing container
- run ceph-volume (to gather device inventory, create osds, zap, etc.)
- gather a host inventory of services (containers)
The original tool was more like "ceph daemon tool" but it was shortened to
ceph-daemon at the start.
We voted on some alternatives here:
https://pad.ceph.com/p/ceph-daemon-tool
but the winner is currently 'cephctl' with is IMO a non-starteer.
Usually 'ctl' utilities are for interacting with running systems/daemons
via some runtime API--that's basically what the 'ceph' CLI utility is.
ceph-daemon is more akin to kubeadm or ceph-deploy or something like
that.
So... I shortened/pruned the list again. Please weigh in. And if you
have a bright idea for a better name, feel free to add it.
A "pseudomorph" [1] is a fake body made of ink/mucus left behind by
cephalopods attempting to escape. I couldn't help but think of the
vintage xkcd comic about getting someone to do what you want [2]. So
I'm putting forth:
pseudo-ceph
$ ceph start osd
What? Make it yourself.
$ psuedo-ceph start osd
Okay.
