encg / caddy-cloudflare-crowdsec

Caddy Docker image with Cloudflare DNS and CrowdSec bouncer modules

caddy-cloudflare-crowdsec

Caddy Docker image with the following modules included:

• https://github.com/mholt/caddy-l4
• https://github.com/caddyserver/transform-encoder
• https://github.com/hslatman/caddy-crowdsec-bouncer
• https://github.com/caddy-dns/cloudflare

Why?

I've been using Docker for years, but have never built an image. Also couldn't find a Caddy image with the aforementioned modules included.

Usage

docker-compose.yml

version: "3.8"
services:
  caddy:
    image: encg/caddy-cloudflare-crowdsec
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
      - "443:443/udp"
    volumes:
      - $PWD/Caddyfile:/etc/caddy/Caddyfile
      - caddy_data:/data
      - caddy_config/config

volumes:
  caddy_data:
    external: true
  caddy_config:

.env

CF_API_TOKEN=cloudflare_api_token
CS_LOCAL_API_KEY=crowdsec_local_api_key

Caddyfile

{
	acme_dns cloudflare {$CF_API_TOKEN}
	crowdsec {
		api_url http://crowdsec:8080
		api_key {$CS_LOCAL_API_KEY}
		ticker_interval 15s
		#disable_streaming
		#enable_hard_fails
	}
}
