I tried to deploy it to Fly - initially using flyctl launch but then switching to flyctl deploy so I could use the --build-arg option (posted a feature request here).

Almost got it working, but it failed the health check: `` % cd datasette/demos/apache-proxy apache-proxy % flyctl launch Creating app in /Users/simon/Dropbox/Development/datasette/demos/apache-proxy Scanning source code Detected Dockerfile app Automatically selected personal organization: Simon Willison ?

I didn't pass the build argument, trying again with flyctl deploy
