archive method
Downloads a file or directory from the container's filesystem as a tar archive.
Sends GET /containers/{id}/archive?path={path} and returns the raw
tar bytes.
Implementation
Future<Uint8List> archive(String id, String path) async {
final resp = await _request(
'GET',
'/containers/$id/archive',
queryParams: {'path': path},
);
_throwIfError(resp);
return resp.body;
}
