For cloudflare tunnels no, it does a nat punch through I think it's called, where it connects from inside your network out to 2 edge locations to cloudlfare, where it then can send traffic back and forwards.
If I wanted to expose by port forwarding, then yes you are correct, I could configure ddns.
Personally, I would configure my own version of DDNS where it's just a cron job once every 5 minutes to run terraform and check if my public IP has changed, and if it has run an apply.
Does that answer the question?
Whoa that’s a clever solution for ddns
Ye, I though tunnels needed a public ip still but it makes sense it doesn’t given there’s a service running in your network that can do that check
There's a great tiny little program/docker container called cf-ddns that is great for this
