export

Usage:  docker export [OPTIONS] CONTAINER

Export a container's filesystem as a tar archive

Options:
      --help            Print usage
  -o, --output string   Write to a file, instead of STDOUT

The docker export command does not export the contents of volumes associated with the container. If a volume is mounted on top of an existing directory in the container, docker export will export the contents of the underlying directory, not the contents of the volume.

Refer to Backup, restore, or migrate data volumes in the user guide for examples on exporting data in a volume.

Examples

$ docker export red_panda > latest.tar

Or

$ docker export --output="latest.tar" red_panda
