Finally, we can mount the named volume to this data directory:

```bash
docker run -v date-volume:/data my-image
docker run -v date-volume:/data my-time-image
```

This runs a container from my-image and mounts the `date-volume` Docker volume to the /data directory in the container. Anything written to `/data` inside the container will now be written to the `date-volume` on the host instead of the container's ephemeral file system. This allows the data to persist. Once the container exits, the date output file is safely stored on the host volume.
