The feature

The number of environmental variables for this is starting to get out of control. Could you consider, from a Docker perspective, instead of having to define dozens of environmental variables, instead having a single config file mounted into the container instead?

Hi @nwithan8,

I have some good news, technically this is already possible.
See the Home Assistant addon injects its configuration into a specific location within the container for me to read it.

And you could utilize this as well. It works like this:

options.json:

{
  "unifi_ip": "192.168.1.1"
}

docker-compose.yml:

services:
  unifi-voucher-site:
    image: glenndehaan/unifi-voucher-site:latest
    ports:
      - "3000:3000"
    volumes:
      - options.json:/data/options.json

You basically lowercase the now already available environment variables.
I will update the README to reflect this option is also available for people who don't like the environment variables.

Kind regards,
Glenn de Haan
