Represents a Kubernetes node pool as a child resource of a [KubernetesEnvironmentResource](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesenvironmentresource.md). Node pools can be referenced by compute resources to schedule workloads on specific node pools using [KubernetesEnvironmentExtensions.WithNodePool(IResourceBuilder<T>, IResourceBuilder<KubernetesNodePoolResource>)](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesenvironmentextensions/methods.md#withnodepool-iresourcebuilder-t-iresourcebuilder-kubernetesnodepoolresource).

## Definition

```csharp
namespace Aspire.Hosting.Kubernetes;

public class KubernetesNodePoolResource
    : Aspire.Hosting.ApplicationModel.Resource,
      Aspire.Hosting.ApplicationModel.IResource,
      Aspire.Hosting.ApplicationModel.IResourceWithParent,
      Aspire.Hosting.ApplicationModel.IResourceWithParent<Aspire.Hosting.Kubernetes.KubernetesEnvironmentResource>
{
    // ...
}
```

## Constructors

- [KubernetesNodePoolResource(string, KubernetesEnvironmentResource)](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesnodepoolresource/constructors.md#constructor-string-kubernetesenvironmentresource) -- Represents a Kubernetes node pool as a child resource of a [KubernetesEnvironmentResource](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesenvironmentresource.md). Node pools can be referenced by compute resources to schedule workloads on specific node pools using [KubernetesEnvironmentExtensions.WithNodePool(IResourceBuilder<T>, IResourceBuilder<KubernetesNodePoolResource>)](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesenvironmentextensions/methods.md#withnodepool-iresourcebuilder-t-iresourcebuilder-kubernetesnodepoolresource).

## Properties

- [NodeSelectorLabelKey](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesnodepoolresource/properties.md#nodeselectorlabelkey) : `string` `get; init` -- Gets the label key used to identify the node pool in the Kubernetes cluster. Defaults to `agentpool` which is the standard label used by AKS and many managed Kubernetes services.
- [Parent](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesnodepoolresource/properties.md#parent) : [KubernetesEnvironmentResource](/reference/api/csharp/aspire.hosting.kubernetes/kubernetesenvironmentresource.md) `get` -- Gets the parent Kubernetes environment resource.
