Public bug reported:
For magnum 7.0.1 package (Rockyrelease) the keystone_auth section is
inconsistent to the keystone mainstream config
When configuring in /etc/magnum/magnum.conf
auth_uri = https://controller:5000/v3
then the /var/log/magnum-api.log contains a warning
WARNING oslo_config.cfg [-] Deprecated: Option "auth_uri" from group
"keystone_authtoken" is deprecated for removal (The auth_uri option is
deprecated in favor of www_authenticate_uri and will be removed in the S
release.). Its value may be silently ignored in the future.
magnum related openstack cli commands properly work, eg
# openstack coe cluster list
+--+---+-++--+---+
| uuid | name | keypair | node_count |
master_count | status|
+--+---+-++--+---+
| ae2395b8-8616-4721-b5de-9134472496cb | swarm-cluster | None| 1 |
1 | CREATE_FAILED |
| 5d6651a0-7be4-42ff-ad28-bd93633761c2 | swarm-cluster | None| 1 |
1 | CREATE_FAILED |
+--+---+-++--+---+
so far so good
BUT: when you configure
www_authenticate_uri = https://controller:5000/v3
(as it should be indeed latest since pike)
Then any kind of openstack cli command with magnum elements fails with
'NoneType' object has no attribute 'replace' (HTTP 500) (Request-ID:
req-e6701428-5395-40c4-9b64-f0d4765501e9)
