Subject: Re: [Openstack] How should an instance learn what tenant it is in?
Hi Andrew,
I'm considering rewriting this hack to write the tenant name into
the metadata directly, but that will still be a hack.
That's what many of our customers are doing, and I agree that it's hack.
We recently changed the names of some projects, and updating the
metadata is no fun.
If not, would a
nova patch that adds tenant id and name to the metadata be welcome?
We would welcome it. It should respect project renames, of course. :)
I'd suggest just storing the tenant id and then doing the lookup in the CLI
tools to be human friendly. The image handling seems to work this way so
copying the same structure as the image field would be consistent.

Yeah, I agree -- the tenant id is something that nova surely already
knows... The tenant name seems like a different can o' worms.
Anyway, I'll try to have a look at coding this up in the next few
weeks. In the meantime I'm just sticking it in metadata myself via a
custom hook.
Thanks for the suggestions, everyone!

cheers, Jan

This could also be supplied by config drive/metadata service trivially. I
wouldn't overthink it (nova already knows).
