Hello,
I’ve successfully deployed a Sinatra app an this URL: https://young-fire-8360.fly.dev/
Subsequently, I’ve updated the CNAME and ALIAS DNS records on my domain registrar with the above URL; they are now pointing at the right IP address.
How do I configure my Fly.io hosting package so that I can use my own domains instead of the system-generated one above?
Thank you!
Hi @fullstackplus
You can’t remove the fly.dev
address but you can use your own domain. It sounds like you’ve already setup the required DNS records so nothing more should be needed.

Hi @charsleysa
Apologies if my question was unclear, but what I need is for the above website to be accessible at:
So I was asking how to make the above domain (which I own) point to the fly.dev
address.
Hi @fullstackplus! You can find the official documentation for custom domains here:
Since you’ve already configured the records to point your domains at your Fly app, I think all you’ll need to do is create certificates for them, i.e., running the following for your app:
fly certs create fullstackplus.tech
fly certs create www.fullstackplus.tech
You can then use fly certs list
to check that they’re issued.
