Keystone Discovery Warnings Displayed

[Mike Perez]

Discovery is now in Cinder client https://review.openstack.org/#/c/145613/ , but when the Keystone catalog contains a url that has a version in it, it displays warnings:

WARNING:keystoneclient.auth.identity.base:Failed to contact the endpoint at http://172.30.128.4:8776/v1/4af36bb30e4e43ffa837a3fd71c22c3f for discovery. Fallback to using that endpoint as the base url.

This is when Cinder is doing its initial endpoint discovery.

Adding Keystone client after talking to Morgan about it.

Maybe it could be suppressed?

Mike: what you are looking for is: https://github.com/openstack/python-keystoneclient/blob/master/keystoneclient/discover.py#L310

It's in preperation for a catalog that contains ONLY the root url - in the mean time we need to hack off anything that is excess. We do this with keystone already where we need to remove the /v2 from the urls in the catalog.

https://github.com/openstack/python-keystoneclient/blob/master/keystoneclient/_discover.py#L313

in the main cinderclient file you want to add something like:

from keystoneclient import discover

discover.add_catalog_discover_hack('volume', '/v[12]/\w+/?$', '/')

my regex is probably off.

    Add version removal rule to stop discovery warning

    Cinder recently added version discovery leveraging Keystone Client. For
    cases where the service catalog still contains version numbers, this can
    result in Keystone attempting to do discovery at the base url with the
    version number and giving warnings. This will set a version removal rule
    so Keystone can find the correct base url.
