From 7baf904cffdc4074ba5529b095f98a8c1ed6707a Mon Sep 17 00:00:00 2001 From: Radostin Stoyanov Date: Sat, 26 Aug 2017 21:42:04 +0100 Subject: Enable UID/GID mapping for qcow2 Apply ownership mapping in qcow2 images using libguestfs python bindings. To make this solution more general we introduce function guestfs_walk() which will return the root file system tree of disk image along with UID/GID values. These changes are applied in additional qcow2 disk image using the last layer as backing file. For FileSource this is layer-1.qcow2 with backing file layer-0.qcow2. --- src/virtBootstrap/sources/file_source.py | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/virtBootstrap/sources/file_source.py') diff --git a/src/virtBootstrap/sources/file_source.py b/src/virtBootstrap/sources/file_source.py index 69f024c..b4b29ce 100644 --- a/src/virtBootstrap/sources/file_source.py +++ b/src/virtBootstrap/sources/file_source.py @@ -41,10 +41,14 @@ class FileSource(object): @param uri: Path to tar archive file. @param fmt: Format used to store image [dir, qcow2] + @param uid_map: Mappings for UID of files in rootfs + @param gid_map: Mappings for GID of files in rootfs @param progress: Instance of the progress module """ self.path = kwargs['uri'].path self.output_format = kwargs.get('fmt', utils.DEFAULT_OUTPUT_FORMAT) + self.uid_map = kwargs.get('uid_map', []) + self.gid_map = kwargs.get('gid_map', []) self.progress = kwargs['progress'].update_progress def unpack(self, dest): @@ -73,6 +77,9 @@ class FileSource(object): progress=self.progress ) img.create_base_layer() + if self.uid_map or self.gid_map: + logger.info("Mapping UID/GID") + utils.map_id_in_image(1, dest, self.uid_map, self.gid_map) else: raise Exception("Unknown format:" + self.output_format) -- cgit
