Thanks for sharing. It’s great to see improvements on cloudflared, so don’t have to run multiple cloudflared instances.
I see this in relation to my question it does not quite solve the problem. Cloudflared needs to keep its own config so I can operate CloudFlare DNS with, for example,
cloudflared tunnel register website website.example.com:80 8080 && cloudflared tunnel start website so it is scriptable without having to SED an existing configuration and restart cloudflared.
