Overview
ResourceQuota object enumerates hard resource usage limits per project.
ClusterResourceQuota object enumerates hard resource usage limits across the cluster.
After a quota is first declared on a project, the system restricts the ability to create new resources that may exceed the quota until usage statistics are calculated. If the resource creation request exceeds the quota, the server will deny the action and will return an error message.
When a resource is created, the quota usage is updated immediately. When a resource is delete, the quota usage is updated during the next full per-project statistics update.
