# VolumeNodeAffinityV1 Properties

- Package: [Aspire.Hosting.Kubernetes](/reference/api/csharp/aspire.hosting.kubernetes.md)
- Type: [VolumeNodeAffinityV1](/reference/api/csharp/aspire.hosting.kubernetes/volumenodeaffinityv1.md)
- Kind: `Properties`
- Members: `1`

Represents the volume node affinity configuration in Kubernetes. VolumeNodeAffinityV1 describes the node-specific constraints for a PersistentVolume to ensure storage resources are bound to specific nodes based on the required scheduling and node affinity rules.

## Required

- Name: `Required`
- Modifiers: `get; set`
- Returns: [NodeSelectorV1](/reference/api/csharp/aspire.hosting.kubernetes/nodeselectorv1.md)
- Source: [GitHub](https://github.com/microsoft/aspire/blob/5bd693ae1897dee5e2ce71c2cc08879c1c7eff51/src/Aspire.Hosting.Kubernetes/Resources/VolumeNodeAffinityV1.cs)

Defines the required node affinity constraints for scheduling a Kubernetes volume.

```csharp
public NodeSelectorV1 Required { get; set; }
```

## Remarks

This property specifies mandatory node selection criteria using a [NodeSelectorV1](/reference/api/csharp/aspire.hosting.kubernetes/nodeselectorv1.md) object. The criteria are used to determine the nodes on which a Kubernetes volume can be scheduled. It enables the definition of strict scheduling constraints that must be met for a node to be eligible.
