Initialize unset environment variables from web UI #2098
Description
Some applications' docker containers expose settings only via environment variables, for example:
- paperless: PAPERLESS_URL=
- vaultwarden: ADMIN_TOKEN and DOMAIN
Rather than editing the docker-compose.ym and having it overwritten on every update, or hoping the submitter of an app added an option for reading a .env file from the data directory, i think it would be useful to be able to set these variables within the UI perhaps while preventing the ones set in thge docker-compose.yml from being overridden to avoid breaking applications or hide this option behind the advanced settings?.
