Lovely! Is it possible to inject SSID and passphrase parameters as env vars into the Docker container and have a png or pdf render without the web interface?

Edit: Thank you to those who replied!

You can generate QR codes using qrencode (available in most distros package repos), as follows:

qrencode -o wifi.png "WIFI:T:WPA;S:<SSID>;P:<PASSWORD>;;"

qrencode is in debian/ubuntu (https://fukuchi.org/works/qrencode/)

    qrencode -t ansiutf8 'WIFI:T:WPA;S:{ssid};P:{password};;'
No docker required ...

I’m on a Mac, so I would need Docker if the tool wasn’t built for Mac (only Linux).

No, you can just install it via Homebrew.

brew install qrencode
