Run it with
docker run --network="host" -v "${PWD}/output:/output" -v "${PWD}/config:/config" -v "${PWD}/meta:/meta" schemaspy/schemaspy -configFile /config/schemaspy.properties -meta /meta
against a running SORMAS postgres database to generate a static website.
Once the command succeeds, open output/public/index.html with your browser and start exploring.
Configuration and connection settings are under config.
Comments and documentation for the database, tables and columns go into meta/public.meta.xml. The information there is
incorporated in the final static website.
