Lite Spec: Introduce db sync --check feature
- problem
-
It is very hard for automation of deploy and upgrade operations to know if there are db migrations pending. It requires the automation to know what the latest version is, and compare that to the output of a command to check the current version, then interpret the potential difference somehow.
- solution
-
Similar to the linked feature added to Keystone's manage command, Glance should support an operation which enumerates any outstanding db upgrade operations and provide a distinct return code based on that status. Each expand, migrate, and contract operation required to upgrade the db should be listed in the proper order of execution in the response. For consistency with Keystone, this may be implemented by using a
--check
option. When this option is present no db upgrades would be performed but potential operations would be reported, acting similar to the pattern of a dry-run. - impacts
-
Introduces new option to the db sync operation in glance-manage.
- timeline
-
Expected to be merged within the Pike time frame.
