A tenant's GPU budget is declared per class as <class>.gpuclass.cozystack.io/devices and over every class as gpuclass.cozystack.io/devices. These keys are not pod resources, so no ResourceQuota enforces them. The proposal hands the check to the pool-wide admission gate that counts declared sizes; until that gate is on, the Cozystack API server does it for GPU keys only, with the inputs and the pool arithmetic that gate reads, so the switch changes no verdict. On a VMInstance or KubernetesNodes create or update, every class entry reserves its count, times maxReplicas for a worker pool, read from the chart-defaulted values. The tenant pool arithmetic is applied to the declared resourceQuotas and these entries. Only growth is checked on an update, so shrinking and unchanged entries pass even in a pool that is already over budget. Like the gate it stands in for, this is a read-check-write without a transaction. The tenant declaration gate already treats GPU keys like any other; it now reads their pool usage from the class entries, since the ResourceQuota it reads for other keys never carries them. It also refuses a key in the GPU budget domain that is not a budget key: the tenant chart keeps such a key out of the ResourceQuota, so nothing would enforce it.

Cozystack
Cozystack is a free and open-source platform and framework for building clouds.
Cozystack is a CNCF Sandbox project that was originally built and sponsored by Ænix.
With Cozystack, you can transform a bunch of servers into an intelligent system with a simple REST API for spawning Kubernetes clusters, Database-as-a-Service, virtual machines, load balancers, HTTP caching services, and other services with ease.
Use Cozystack to build your own cloud or provide a cost-effective development environment.
Use-Cases
-
Using Cozystack to build a public cloud
You can use Cozystack as a backend for a public cloud -
Using Cozystack to build a private cloud
You can use Cozystack as a platform to build a private cloud powered by Infrastructure-as-Code approach -
Using Cozystack to build your own platform
You can install only the Cozystack components you need on an existing Kubernetes cluster
