caddy-cloudflare

Please see the official Caddy Docker Image for deployment instructions.

Builds are available at the following Docker repositories:

• GitHub Container Registry: ghcr.io/slothcroissant/caddy-cloudflaredns

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 CLOUDFLARE_EMAIL=[e-mail] \
     -e CLOUDFLARE_API_TOKEN=12345 \
     -e ACME_AGREE=true \
     slothcroissant/caddy-cloudflaredns:latest
   

   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.

   tls {$CLOUDFLARE_EMAIL} { 
     dns cloudflare {$CLOUDFLARE_API_TOKEN}
   }
   

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: n-hass/caddy-cloudflare:2.7.4
