Hi Martinx,
Thanks for your feedback. You're not the only person to have been affected.
The (lack of) backwards compatibilty of the v2 CLI is captured here:
https://wiki.openstack.org/wiki/Glance-v2-v1-client-compatability
A small number of these incompatabilities are due to unmaskable differences
between the v2 and v1 APIs, but most (like image-create --location) are not.

Guys,
I want to formalize my protest against Glance V2 usability.
With Glance V1, you can straight away, add an image based on its remote
URL location, then, Glance will download the image ONLY when someone launch
it.
This is very cool and I can add, easily and automatically by Ansible, for
example, dozens of images at once, right after deploying OpenStack.
However, this is much worse now, when with Glance V2, as follows:
-----
*** Glance V1 procedure:
1) Add an image and its remote location at once:
glance image-create --location
http://cdimage.debian.org/cdimage/openstack/8.3.0/debian-8.3.0-openstack-amd64.qcow2
--is-public true --name "Debian 8.3.0 - Jessie - 64-bit - Cloud Based
Image" --container-format bare --disk-format qcow2
See it? Glance V1 is awesome!
--
*** Glance V2 procedure:
1) Add an Image WITHOUT a location:
glance image-create --visibility public --name \"Debian 8.3.0 - Jessie -
64-bit - Cloud Based Image\" --container-format bare --disk-format qcow2
2) Look (or parse somehow) the stdout, copy to clipboad the Image ID.
3) Add the location of the image:
glance location-add --url
http://cdimage.debian.org/cdimage/openstack/8.3.0/debian-8.3.0-openstack-amd64.qcow2
$PASTE_IMAGE_ID
See it? Glance V2 sucks.

It is more complicated now, specially to automate this with Ansible or
other tool! Because there is a need to parser the stdout of step "1" and
store the Image ID somewhere (like a variable), and then, add the remote
location URL for the image.
Please guys, do something about this!
NOTE: I will be happy to be wrong here, let me know if I am missing
something.
I believe that, if the "glance location-add" starts to accept "image name"
(instead of only ID), it will make the automation easier, because the name
is predictable, and the ID is random. Or, if someone tells me how to
auto-generate random IDs for OpenStack, so it will be predictable (I'll be
able to use auto-genarated ID with "image-create", I believe), then, it
will also make the automation easier, I'll be okay with that too!
Thanks in advance!
Regards,
Thiago
