I tesed this by first building and running a container using the new Dockerfile from #114: docker build . docker run -it -p 8001:8001 6c9ca7e29181 /bin/sh Then I ran this inside the container itself: apt update && apt-get install wget -y \ && wget http://www.gaia-gis.it/spatialite-2.3.1/test-2.3.sqlite.gz \ && gunzip test-2.3.sqlite.gz \ && mv test-2.3.sqlite test23.sqlite \ && datasette -h 0.0.0.0 test23.sqlite I visited this URL to confirm I got an error due to spatialite not being loaded: http://localhost:8001/test23-c88bc35?sql=select+ST_AsText%28Geometry%29+from+HighWays+limit+1 Then I checked that loading it with `--load-extension` worked correctly: datasette -h 0.0.0.0 test23.sqlite \ --load-extension=/usr/lib/x86_64-linux-gnu/mod_spatialite.so Then, finally, I tested it with the new environment variable option: SQLITE_EXTENSIONS=/usr/lib/x86_64-linux-gnu/mod_spatialite.so \ datasette -h 0.0.0.0 test23.sqlite Running it with an invalid environment variable option shows an error: $ SQLITE_EXTENSIONS=/usr/lib/x86_64-linux-gnu/blah.so datasette \ -h 0.0.0.0 test23.sqlite Usage: datasette -h [OPTIONS] [FILES]... Error: Invalid value for "--load-extension": Path "/usr/lib/x86_64-linux-gnu/blah.so" does not exist. Closes #112

Improves the Dockerfile to support spatial datasets, work with the local datasette code (Friendly with git tags and Dockerhub) and moves to slim debian, a small image easy to extend via apt packages for sqlite.
