I’m using the pre-built Docker image (ghcr.io/aeharding/wefwef:latest). I’m using CloudFlare Access to control access to the app and make it accessible outside my network.
I can’t write up the step-by-step instructions at the moment, but there are literally two commands to run to get the Docker container up and running (see the project’s GitHub page for more info). For the CloudFlare side of things, there are a ton of helpful videos out there that walk through the process in detail.
