Export a container’s filesystem as a tar archive
docker export [OPTIONS] CONTAINER
| Name, shorthand | Default | Description |
--output , -o | Write to a file, instead of STDOUT |
| Command | Description |
|---|---|
| docker | The base command for the Docker CLI. |
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.
Each of these commands has the same result.
$ docker export red_panda > latest.tar
$ docker export --output="latest.tar" red_panda
