I'm not saying that there's no other way to do this -- e.g., you could do
all sorts of alternative workflows and configurations in the "regular"
upload process -- but the feedback I got can be summarized like this:
Given the importance of a properly-functioning Glance for normal cloud
operations, it is useful to have one upload/download workflow that is
locked down and you don't have to worry about, and a completely different
workflow that you can expose to end users and tinker with as necessary.
IMHO - a cloud that does not allow me to upload images is not a usable
cloud.
A cloud that requires me to upload images differently than another cloud
is a hardship on the users.
A cloud that makes the user know the image format of the cloud is a
hardship on the users, especially when there exist nowhere in any
existing distro tools that can actually produce the image format in
question. (yup, Im just going to sneak that one in there)
NOW - I think that the task api and the image conversion tools itself if
it's a behind the scenes kind of thing is potentially nice thing.
If "glance import-from http://example.com/my-image.qcow2' always worked,
and in the back end generated a task with the task workflow, and one of
the task workflows that a deployer could implement was one to do
conversions to the image format of the cloud provider's choice, that
would be teh-awesome. It's still a bit annoying to me that I, as a user,
need to come up with a place to put the image so that it can be
imported, but honestly, I'll take it. It's not _that_ hard of a problem.
I predicted the above problems with the tasks API as it was designed way
back in 2013 and urged it be redesigned:

where I actually agreed with George Reese about something...
Guess I should have been more vocal.
