Driver Internal Info¶
https://blueprints.launchpad.net/ironic/+spec/driver-internal-info
Problem description¶
Driver should have its own infos which cannot manipulated by user/admin. These infos are not input from admin like driver_info and they may vary during the deployment process. They can only be used by driver itself.
One example is ipmitool. Not all IPMI firmware support set boot device persistent, so we need to save this locally.
Proposed change¶
Add a new internal attribute
driver_internal_infoin nodes table, which cannot modify by Admin/user by calling node.update APIModify node.update to clear
driver_internal_infowhen update driver via node.update API.
Alternatives¶
Saving these infos in a new table named driver_interal_info.
Data model impact¶
Add a new internal attribute driver_internal_info in node table. This
field is a json dict.
REST API impact¶
The driver_internal_info field should be added to the node details API.
