On fly.io. This particular database goes from 1.4GB to 200M. Slower, part of that might be having no --inspect-file?

``` $ datasette publish fly ... --generate-dir /tmp/deploy-this ... $ mksquashfs large.db large.squashfs $ rm large.db # don't accidentally put it in the image $ cat Dockerfile FROM python:3.8 COPY . /app WORKDIR /app

ENV DATASETTE_SECRET 'xyzzy' RUN pip install -U datasette

RUN datasette inspect large.db --inspect-file inspect-data.json

ENV PORT 8080 EXPOSE 8080 CMD mount -o loop -t squashfs large.squashfs /mnt; datasette serve --host 0.0.0.0 -i /mnt/large.db --cors --port $PORT ```

It would also be possible to copy the file onto the ~6GB available on the ephemeral container filesystem on startup. A little against the spirit of the thing? On this example the whole docker image is 2.42 GB and the squashfs version is 1.14 GB.
