As of today, nova-compute can access data only through conductor. You should not have database connection details in nova.conf for nova-compute - if you do, this should raise an exception. However you're referring the Pike release and back then having db details in config wasn't considered as error at least. But I still doubt that nova-compute was accessing DB directly even then. пн, 9 янв. 2023 г., 18:04 Huy Võ Lê <volehuy1998@gmail.com>:
Hi, I have a question about Nova role
- Assert: I don't understand about OPS/Redhat explaination. Because all of information said nova-conductor will help database-accessing for nova-compute, every chart/image showed, too.
- Reallity: When I download OPS Nova source code looked into nova/compute/manager.py, I saw the many many block code that queries the data from the database (instance list) and updates the data (instance.save).
So the assertion of the Openstack and Redhat development community is wrong or true????
