-   `commit` (bool) - If true, the container will be committed to an image rather than exported.
    
-   `discard` (bool) - Throw away the container when the build is complete. This is useful for
    the [artifice
    post-processor](https://www.packer.io/docs/post-processors/artifice.html).
    
-   `export_path` (string) - The path where the final container will be exported as a tar file.
    
-   `image` (string) - The base image for the Docker container that will be started. This image
    will be pulled from the Docker registry if it doesn't already exist.
    
-   `message` (string) - Set a message for the commit.
