unable to generate a certificate for the domains [traefik.domain.com]:

[tchiaspko]

I created a cloudflare api token and replace it. Also i replaced the two email address like it said in the README.md. However when I run docker-compose up I get the following

Am I suppose to register a domain with cloudflare and replace DOMAIN.com with my own domain?

You don't need to register your domain in cloudflare but indeed you have to change configuration with your own domain name. Don't forget to onboard your domain to cloudflare.
