# ContainerResource.withContainerName

- Module: [Aspire.Hosting](/reference/api/typescript/aspire.hosting.md)
- Defined on: [ContainerResource](/reference/api/typescript/aspire.hosting/containerresource.md)
- Version: `13.4.0`
- Kind: `method`

Overrides the default container name for this resource. By default Aspire generates a unique container name based on the resource name and a random postfix (or a postfix based on a hash of the AppHost project path for persistent container resources). This method allows you to override that behavior with a custom name, but could lead to naming conflicts if the specified name is not unique.
