Dose Caddy DNS challenge needs Email Address？

[toyo2333]

hi，i just read your blog ：https://samedwardes.com/2023/11/19/homelab-tls-with-caddy-and-cloudflare/

what i confused is some other article said it needs a email （cloudflare email address）：

https://emby.media/community/index.php?/topic/102088-emby-caddy-v2-setup-with-cloudflare/
https://github.com/SlothCroissant/caddy-cloudflaredns

so what is the difference? which one is the correct way to config it?

thanks

Ray

Hi Ray,

Thank you for the question, and I apologize for the delay. In my experience, you do NOT need an email address. The only thing that Caddy needs to "talk" to Cloudflare is the API token. My example Caddyfile will work assuming you have CLOUDFLARE_API_TOKEN set as an environment variable.

test.edwardes.xyz {
    # Set this path to your site's directory.
    root * /usr/share/caddy

    # Enable the static file server.
    file_server

    tls {
        dns cloudflare {env.CLOUDFLARE_API_TOKEN}
    }
}

Does this work for you?
