U413

External Dependencies

• PostgreSQL

How to run

To connect to the database, u413 uses the following environment variables:

• PGUSER/USER (defaults to whoami)
• PGDATABASE/DB (defaults to "u413")
• PGPASSWORD/PASS

Typically you'd just run tools/run, but a docker file has been included to ensure portability. To run that, docker build . -t u413 just once, then docker run -p$HOSTPORT:8080 --name u413 -t u413.

Make sure the postgreSQL server is running.

Utilities

• tools/query allows the invocation of named SQL queries, eg tools/query nuke
• tools/run uses files from private/ to start the server with a simple invocation
  • db.pwd gives the password for the server (make sure this has proper permissions!!)
• tools/genssl generates SSL certificates (NOTE: doesn't work yet)
