slothcroissant/caddy-cloudflaredns repository overview

⁠caddy-cloudflaredns

Please see the official Caddy Docker Image⁠ for deployment instructions.

Few things to note:

1. You should add CLOUDFLARE_EMAIL and CLOUDFLARE_API_TOKEN as environment variables to your docker run command. Example:

   docker run -it --name caddy \
     -p 80:80 \
     -p 443:443 \
     -v caddy_data:/data \
     -v caddy_config:/config \
     -v $PWD/Caddyfile:/etc/caddy/Caddyfile \
     -e [email protected] \
     -e CLOUDFLARE_API_TOKEN=12345 \
     -e ACME_AGREE=true \
     slothcroissant/caddy-cloudflaredns:latest
   

   Copy

   You can obtain your Cloudflare API token⁠ via the Cloudflare Portal. To create a API token with minimal scope, the following steps are needed:

   1. Log into your dashboard, go to account settings, create API token

   2. grant the following permissions:

      • Zone / Zone / Read
      • Zone / DNS / Edit

2. You should add the following to your Caddyfile as the tls directive⁠. Note that I haven't figured out why the using {env.CLOUDFLARE_EMAIL} for the email address didn't work, so for now I've got it manually declared:

   tls [email protected] { 
     dns cloudflare {env.CLOUDFLARE_API_TOKEN}
   }
   

   Copy

3. This image now supports tagging! See available tags here⁠. To select a specific version of caddy, set your Docker image tag⁠ to the caddy version you'd like to use.

   Example: slothcroissant/caddy-cloudflaredns:2.4.3
