# Add nginx as a reverse proxy, forwarding 8080 to 8081.

# On launch we use the manage.py script to invoke runserver on port 8000. We
# need to run inside a poetry shell. 
# Commented out: this is the command we would like to use.

# However we need to launch nginx too, so this is the workaround script.
