Certified Stacks
Certified Stacks are tested StackTemplates and supporting resources bundled with vCluster Platform. They package multi-application integrations that need dependency ordering, health gates, and shared configuration.
Bundled StackTemplates carry the certified marker and are read-only. They use the same StackTemplate and StackInstance APIs as custom Stacks.
Understand the certified catalog​
Platform 4.12 includes the NVIDIA Run:ai certified bundle. It contains four StackTemplates, two VirtualClusterTemplates, and the Apps those templates reference.
| Integration | Deployment models | Components |
|---|---|---|
| NVIDIA Run:ai | Dedicated control plane and central control plane | vCluster, NVIDIA GPU components, and NVIDIA Run:ai 2.26 |
The bundle is pinned in each Platform release. The upstream certified-stacks repository contains its source manifests, tests, and exhaustive implementation guidance.
Use a certified stack​
Choose a deployment model on the integration page. Then use the administrator guide to validate prerequisites and follow the supported lifecycle:
Certified Stack orchestration doesn't have a separate license feature. Each task uses the feature for the resource it creates. The bundled NVIDIA Run:ai templates contain App tasks, and Apps are available on every plan.
Customize a certified stack​
Copy a certified StackTemplate and use a different name when you need to change it. Remove the vcluster.com/certified annotation from the copy. The copy is your resource and doesn't receive changes from later certified bundles.
Keep the bundled object unchanged so its source and support status remain clear. Review task dependencies, fixed names, chart versions, and output namespaces together when modifying a copy.
Understand the previous workflow​
Earlier Certified Stacks are repository-based reference implementations. They can include Terraform, Helm, and other orchestration outside the Stack API. Those implementations remain available in the repository for users who rely on them.
The native Platform 4.12 bundle is a separate delivery model. It seeds StackTemplates directly into Platform and lets users install StackInstances through the UI or management API.
