### HOW TO USE
# Forwards host port 5432 (change if necessary)
# Creates a user "vagrant" with password "vagrant" and database called "vagrant".
# "vagrant" user is a superuser.
#
# Example connection string: "postgresql://vagrant:vagrant@localhost:5432/vagrant"
#
# Obviously don't use this for production unless you understand the risks.

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.

    vb.name = "vagrant_debian10_postgresql_fastapitest"
    # Display the VirtualBox GUI when booting the machine
    # vb.gui = true

    # Customize the amount of memory on the VM:
