Can we have nested project quotas in from the beginning ? Nested projects are in Keystone V3 from Kilo onwards and retrofitting this is hard work.
For details, see the Nova functions at https://review.openstack.org/#/c/242626/. Cinder now also has similar functions.

In Magnum, there should be a limitation for user or project to create Magnum resource, and the limitation should be configurable[1]. I proposed following design :- 1. Introduce new table magnum.quotas +------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | created_at | datetime | YES | | NULL | | | updated_at | datetime | YES | | NULL | | | deleted_at | datetime | YES | | NULL | | | project_id | varchar(255) | YES | MUL | NULL | | | resource | varchar(255) | NO | | NULL | | | hard_limit | int(11) | YES | | NULL | | | deleted | int(11) | YES | | NULL | | +------------+--------------+------+-----+---------+----------------+ resource can be Bay, Pod, Containers, etc. 2. API controller for quota will be created to make sure basic CLI commands work. quota-show, quota-delete, quota-create, quota-update 3. When the admin specifies a quota of X number of resources to be created the code should abide by that. For example if hard limit for Bay is 5 (i.e. a project can have maximum 5 Bay's) if a user in a project tries to exceed that hardlimit it won't be allowed. Similarly goes for other resources. 4. Please note the quota validation only works for resources created via Magnum. Could not think of a way that Magnum to know if a COE specific utilities created a resource in background. One way could be to see the difference between whats stored in magnum.quotas and the information of the actual resources created for a particular bay in k8s/COE. 5. Introduce a config variable to set quotas values. If everyone agrees will start the changes by introducing quota restrictions on Bay creation. Thoughts ?? -Vilobh [1] https://blueprints.launchpad.net/magnum/+spec/resource-quota
