small maps using docker

[verajosemanuel]

>docker run --rm -p 8001:8001 -v c/Users/joe/Downloads:/mnt  datasetteproject/datasette datasette -p 8001 -h 0.0.0.0 /mnt/my.db --install=datasette-cluster-map 


Usage: datasette serve [OPTIONS] [FILES]...
Try 'datasette serve --help' for help.

Error: no such option: --install

so i have been trying to install attaching a terminal to running container:

docker exec -i -t ec5b9dd7c551 /bin/bash
root@ec5b9dd7c551:/# datasette install datasette-cluster-map

and then stopped and run the container again. Maps now available but very small. Like a banner above the data. is there any way of setting maps full windows size?
