    12  # export
    13  
    14      Usage: docker export [OPTIONS] CONTAINER
    15      
    16        Export the contents of a filesystem to a tar archive (streamed to STDOUT by default).
    17  
    18        -o, --output=""    Write to a file, instead of STDOUT
    19  
    20        Produces a tarred repository to the standard output stream.
    21  
    22  
    23   For example:
    24  
    25      $ docker export red_panda > latest.tar
    26  
    27     Or
    28  
    29      $ docker export --output="latest.tar" red_panda
    30  
    31  The `docker export` command does not export the contents of volumes associated
    32  with the container. If a volume is mounted on top of an existing directory in
    33  the container, `docker export` will export the contents of the *underlying*
    34  directory, not the contents of the volume.
    35  
    36  Refer to [Backup, restore, or migrate data
    37  volumes](/userguide/dockervolumes/#backup-restore-or-migrate-data-volumes) in
    38  the user guide for examples on exporting data in a volume.
