To Reproduce Steps to reproduce the behavior:
Customer is trying to run tempest in environment where public URL contains 'v2':
| ID | regionOne | keystone | identity | True | public | https://keystone-public-openstack.examplev2.com |
IdentityService class of python-tempestconf has very ambiguous rules to detect keystone v2 endpoints (instead of validating suffix, check returns success if 'v2' can be found anywhere in URL endpoint:
class IdentityService(VersionedService): def __init__(self, name, s_type, service_url, token, disable_ssl_validation, client=None, **kwargs): super(IdentityService, self).__init__( name, s_type, service_url, token, disable_ssl_validation, client, **kwargs) self.extensions_v3 = [] version = '' if 'v2' in self.service_url: version = '/v2.0' url_parse = urllib.parse.urlparse(self.service_url) self.service_url = '{}://{}{}'.format(url_parse.scheme, url_parse.netloc, version) def set_extensions(self): if 'v2' in self.service_url: body = self.do_get(self.service_url + '/extensions') body = json.loads(body) values = body['extensions']['values'] self.extensions = list(map(lambda x: x['alias'], values)) return
So when customer tries to run tempest, they end up getting the following trace:
2026-01-29 09:48:58.796 12 CRITICAL tempest [-] Unhandled error: config_tempest.services.base.ServiceError: Request on service 'identity' with url 'https://keystone-public-openstack.examplev2.com/v2.0/extensions' failed with code 404 2026-01-29 09:48:58.796 12 ERROR tempest Traceback (most recent call last): 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/bin/discover-tempest-config", line 10, in <module> 2026-01-29 09:48:58.796 12 ERROR tempest sys.exit(main()) 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/lib/python3.9/site-packages/config_tempest/main.py", line 617, in main 2026-01-29 09:48:58.796 12 ERROR tempest config_tempest( 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/lib/python3.9/site-packages/config_tempest/main.py", line 559, in config_tempest 2026-01-29 09:48:58.796 12 ERROR tempest services = Services(clients, conf, credentials) 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/lib/python3.9/site-packages/config_tempest/services/services.py", line 42, in __init__ 2026-01-29 09:48:58.796 12 ERROR tempest self.discover() 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/lib/python3.9/site-packages/config_tempest/services/services.py", line 115, in discover 2026-01-29 09:48:58.796 12 ERROR tempest service.set_extensions() 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/lib/python3.9/site-packages/config_tempest/services/identity.py", line 41, in set_extensions 2026-01-29 09:48:58.796 12 ERROR tempest body = self.do_get(self.service_url + '/extensions') 2026-01-29 09:48:58.796 12 ERROR tempest File "/usr/lib/python3.9/site-packages/config_tempest/services/base.py", line 80, in do_get 2026-01-29 09:48:58.796 12 ERROR tempest raise ServiceError("Request on service '%s' with url '%s' failed" 2026-01-29 09:48:58.796 12 ERROR tempest config_tempest.services.base.ServiceError: Request on service 'identity' with url 'https://keystone-public-openstack.examplev2.com/v2.0/extensions' failed with code 404
Expected behavior
I believe that Keystone v2 API endpoint was deprecated for a while, so right decision is to probably drop related code. But if it is impossible, then check should be fixed to validate suffix instead of whole URL.
Bug impact
Acceptance tests are blocked
Known workaround
None: I doubt that endpoint URL can be changed in all situations
