You can easily add your own domains to Coolify or your resources. All domain fields are capable to generate your proxy configurations based on the following rules:
  1. You need to use FQDN (Fully Qualified Domain Name) format: https://coolify.io
  2. You can give multiple domains, separated by comma: https://coolify.io,https://www.coolify.io
  3. You can also add a port to the domain, so the proxy will know which port you would like to map to the domain: https://coolify.io:8080,http://api.coolify.io:3000

​
Wildcard Domain

You can set a wildcard domain (example: http://example.com) to your server, so you can easily assign generated domains to all the resources connected to this server. More details

DNS Validation

Since version beta.191, Coolify will validates DNS records for your domains with 1.1.1.1 Cloudflare DNS server. If you want to use different DNS server, go to your Settings page and change the DNS Servers field (comma separated list).
