11/11/2023 0 Comments Linux untar keep permissionsYou can get around this problem by specifying -no-same-owner, so tar won’t try to set an owner: # tar xzf $INPUT_FOLDER/archive.tar. The problem is that you are executing the command inside /usr/src to which you do not have write permissions with your credentials. Choose Extract Here to extract all files to the current directory. However, when running the image, a non-root user starts the container and any file thus copied with 644 permission cannot execute this copied/added file and if the. The onwner of this file seems to be as root. Then, right click on the file and use either Extract Here to extract the contents in your present location, or Extract To to pick some other destination. When using ADD / COPY in Dockerfile and running the image on linux, the default file permission of the file copied in the image is 644. Since the filesystem /mnt/test-nas/ was mounted via SMB, even root had trouble setting the correct permissions and therefore failed. In your environment’s file manager, navigate to the location of your tar file that you want to open. It turns out that tar tries to preserve the file permissions when run as root: -p, -preserve-permissions, -same-permissionsĮxtract information about file permissions (default for superuser) If you're strictly asking how to set a mandatory file mode with the sftp client you can't (at. SFTP (1) -p Preserves modification times, access times, and modes from the original files transferred. So tar tried to extract the contents of the archive to /mnt/test-nas/ and failed (even as root). The client (OpenSSH sftp) can choose to preserve local permission by using the -p option, which will send the file then fchmod it appropriately. The command in the script looked something like this: # tar xzf $INPUT_FOLDER/ -C /mnt/test-nas/ In a script I was working on, the tar command always reported the following error when I tried to extract an archive: Cannot change ownership to uid 1000, gid 1000: Permission deniedīut I was executing the script as root! The reason for this error to occur turned out to be relatively simple.
