`ClusterMaintenancePolicy` is an interface, so I think your usage in the above code is wrong. What you really want is:
```interface ClusterConfig {
  // properties
  maintenancePolicy: {
    dailyMaintenanceWindow: &lt;insert object here&gt;,
    maintenanceExclusions: &lt;insert object here&gt;,
   };
};```

Oh, that’s sounds good to me. Thank you!

Interfaces are in the `types/input` module of the respective cloud provider. Add a separate import for that and then you'd be able to reuse existing types.

For example, to use the types for resources under the `container` module in the Google Native provider:
```import {container} from "@pulumi/google-native/types/input";```


Oh, perfect. I will give it a try. Thank you, <@UDE2DCFT3>
