nova image-list is deprecated, but it should work even now

[Attila Fazekas]

On newton it looks like:
$ nova image-list
WARNING: Command image-list is deprecated and will be removed after Nova 15.0.0 is released. Use python-glanceclient or openstackclient instead.
ERROR (VersionNotFoundForAPIMethod): API version 'API Version Major: 2, Minor: 37' is not supported on 'list' method.

It is supposed to be still supported, since newton is just 14.

nova (14.0.0.0rc2.dev21)
python-novaclient (6.0.0)

[Matt Riedemann (mriedem)]

This is because the image proxy API bindings are deprecated as of the 2.36 microversion so anything >=2.36 is going to fail.

[Matt Riedemann (mriedem)]

So to be clear, if you pass "--os-compute-api-version 2.35" on the CLI it will still work.

[Augustina Ragwitz (auggy)]

Should we at least update the error message to clearly state it is deprecated?

[Artom Lifshitz (notartom)]

I think this is actually a valid bug in openstackclient. Specifically, the following use case *should* work:

$ export OS_COMPUTE_API_VERSION=2.latest

$ openstack server create --flavor m1.tiny --image cirros-0.3.4-x86_64 --key-name stack --security-group default --nic net-id=059a48f5-fc8e-4721-b694-f2441cf5226f,tag=bla test2

API version 'API Version Major: 2, Minor: 37' is not supported on 'list' method.

It's expected that setting OS_COMPUTE_API_VERSION to latest allows you to boot a server. However, it looks like if the latest on the server side is 2.37 (or later?) booting a VM doesn't work.

    Use image client for images instead of compute

    With the deprecation of the Nova proxy APIs in microversion 2.36 [1],
    any operation that uses a microversion higher than 2.36 and works with
    images will fail because the /images endpoint will return 404. This
    patch updates openstackclient to query images using the image client
    in places where previously the compute client was used.
