## 2. Enable bucket lifecycle configuration

- Create a bucket lifecycle configuration which expires the objects under the prefix `old/` on `2020-01-01T00:00:00.000Z` date and the objects under `temp/` after 7 days.
- Enable bucket lifecycle configuration using `mc`:

```sh
$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {

	}
	return meta.objectLockConfig, meta.ObjectLockConfigUpdatedAt, nil
}

// GetLifecycleConfig returns configured lifecycle config
// The returned object may not be modified.
