Hi,
I'm trying to create a namespace in rados, create a user that has
access to this created namespace and with rados command line utility
read and write objects in this created namespace using the created
user.
I can't find an example on how to do it.
Can someone point me to such example or show me how to do it?
Regards,

Hi
no need to craete a namespace. You just specify the namespace you want to access.
See https://docs.ceph.com/docs/nautilus/man/8/rados/ the -N cli option
For access to a particular namespace have a look at the example here:
https://docs.ceph.com/docs/nautilus/rados/operations/user-management/#modif…

So it's created automatically when I use it through rados command line
utility? Interesting...
See https://docs.ceph.com/docs/nautilus/man/8/rados/
the -N cli option
I had already. From it it's clear to me that the -N option set the
namespace to be used by the rados command line utility but I would
never understand from this man page that the -N option of the rados
command line utility would automatically create the namespace.
For access to a particular namespace have a look at
the example here:
https://docs.ceph.com/docs/nautilus/rados/operations/user-management/#modif…
I had already read these generic instructions.
What I am looking for is one simple working example where I can build
my config from without having to do massive experimentation.

Easiest to think of namespaces just as a prefix for the object name
that is added and removed internally; there isn't really such a thing
as "creating a namespace".
(Yes, the rbd cli utility begs to differ, but that's really just
creating some metadata specific to rbd when you tell it to create a
namespace)
