osc compute quota-class-set

Quota class sets (os-quota-class-sets)

Show, Create or Update the quotas for a Quota Class. Nova supports implicit ‘default’ Quota Class only.

Note

Once a default limit is set via the default quota class via the API, that takes precedence over any changes to that resource limit in the configuration options. In other words, once you’ve changed things via the API, you either have to keep those synchronized with the configuration values or remove the default limit from the database manually as there is no REST API for removing quota class values from the database.

For Example: If you updated default quotas for instances, to 20, but didn’t change quota_instances in your nova.conf, you’d now have default quota for instances as 20 for all projects. If you then change quota_instances=5 in nova.conf, but didn’t update the default quota class via the API, you’ll still have a default quota of 20 for instances regardless of nova.conf. Refer: Quotas for more details.

Warning

There is a bug in the v2.1 API until microversion 2.49 and the legacy v2 compatible API which does not return the server_groups and server_group_members quotas in GET and PUT os-quota-class-sets API response, whereas the v2 API used to return those keys in the API response. There is workaround to get the server_groups and server_group_members quotas using “List Default Quotas For Tenant” API in Quota sets (os-quota-sets) but that is per project quota. This issue is fixed in microversion 2.50, here onwards server_groups and server_group_members keys are returned in API response body.
