## Example

```ts
new go.GoFunction(this, 'GoFunction', {
 entry: 'app/cmd/api',
 bundling: {
      bundlingFileAccess: BundlingFileAccess.VOLUME_COPY,
  },
});
```

## Members

| Member | Description |
| --- | --- |
| `VOLUME_COPY` | Creates temporary volumes and containers to copy files from the host to the bundling container and back. |
| `BIND_MOUNT` | The source and output folders will be mounted as bind mount from the host system This is faster and simpler, but less portable than `VOLUME_COPY`. |
