I followed these steps:

docker run datasetteproject/datasette pip install datasette-upload-csvs

docker commit $(docker ps -lq) datasette-with-plugins

docker run -p 8001:8001 -v $(pwd):/mnt datasette-with-plugins datasette --root -p 8001 -h 0.0.0.0

Visited: http://localhost:8001/-/upload-csvs

I may have missed a step?

Thank you.
