description: Stage Manager is Showrunner's Kubernetes operator. A Performance runs an application, or a published Stage application, with its AuthProxy and its own Ante from a Cratis environment.

Stage Manager is the Kubernetes operator of Showrunner. Unlike the other parts it is not a library an application hosts: it is a service you install in a cluster, and it owns the custom resources of the `showrunner.cratis.io` API group, version `v1alpha1`.

| Resource | What it is | State |
| --- | --- | --- |
| `Performance` | One application running in one Cratis environment, with its AuthProxy and, when it has onboarding, its own Ante. The application can be a published Stage application, and can have a lifetime | Reconciled |
| `Production` | Chronicle, with an optional MongoDB and Vault, for one or more applications | Schema only |
| `Understudy` | How a Production is backed up | Schema only |
| `Restore` | Brings a backup back | Schema only |
| `Rehearsal` | Proves that backups restore | Schema only |
| `BackstagePass` | Who may use the Stage Manager API | Schema only |
| `ControlRoom` | An outbound connection to a control plane | Schema only |

The custom resource definitions are generated from the C# types in `Source/DotNET/StageManager`; there is no hand-written CRD. Schema-only resources can be created and read, and nothing acts on them yet.

- [Install the operator](/showrunner/stagemanager/install/): the Helm chart, its values and the permissions it asks for.
- [Run an application with a Performance](/showrunner/stagemanager/performance/): the spec, what is created, the status and how Ante and AuthProxy are configured.
- [Run a published Stage application](/showrunner/stagemanager/published-stage-applications/): the Stage runtime in published mode with a package, storage, Notes, rollouts, lifetime and usage.
- [Environments and secrets](/showrunner/stagemanager/environments-and-secrets/): how the Cratis environment is resolved and how values reach containers.
