Hey openstack-discuss, we use Ceph RadosGW (Quincy release) to provide Swift as part of an OpenStack cloud. The endpoints are configured as such: > # openstack endpoint list > +----------------------------------+--------+--------------+----------------+---------+-----------+----------------------------------------------------------------------+ > | ID | Region | Service Name | Service > Type | Enabled | Interface | URL | > +----------------------------------+--------+--------------+----------------+---------+-----------+----------------------------------------------------------------------+ > | 1234567890 | region | swift | object-store | True | > public | > https://object-store.region.cloud.example.com/swift/v1/AUTH_%(tenant_id)s > | > | 2345678901 | region | swift | object-store | True | > internal | > https://object-store.region.cloud.example.com/swift/v1/AUTH_%(tenant_id)s > | > | 3456789012 | region | swift | object-store | True | > admin | > https://object-store.region.cloud.example.com/swift/v1/AUTH_%(tenant_id)s > | > so according to https://docs.ceph.com/en/latest/radosgw/keystone/#cross-project-tenant-access, if I am not mistaken. I can also use the openstack client to access containers: > # openstack container list > +---------------+ > | Name | > +---------------+ > | containera | > | containerb | > +---------------+ and there is no warnings or other apparent issues. But when using "project cleanup" via e.g. "openstack project cleanup --dry-run --project $PROJECT" I see multiple warnings like > Failed to contact the endpoint at > https://object-store.region.cloud.example.com/swift/v1/AUTH_f2bc4bd34567ddc341e197456789 > for discovery. Fallback to using that endpoint as the base url. > but only mentioning the swift endpoint. Following the warning string this originates from the discovery method of keystoneauth1, see https://github.com/openstack/keystoneauth/blob/28048af9593740315df8d9027c3bd6cae5e0a715/keystoneauth1/discover.py#L1243. Could anybody help me understand what is issue might be? Why does this warning not appear for every use of object storage / swift via openstackclient? Is there any way for me to "fix" this? Could this even be a bug? Thanks and with kind regards Christian
