caddy2和php-fpm搭配

docker-compose这么写

version: "3.7"
services:
  php:
    image: php:7-fpm
    container_name: php-fpm
    restart: always
    volumes:
      - ./caddy/www:/usr/share/caddy
  caddy:
    image: caddy
    container_name: caddy2
    restart: always
    working_dir : /usr/share/caddy
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./caddy/Caddyfile:/etc/caddy/Caddyfile
      - ./caddy/www:/usr/share/caddy

caddyfile这么写

:80
{
	encode gzip
	root * /usr/share/caddy
	php_fastcgi php:9000
	file_server
	log {
		output discard
	}
}

目录要一致

之前在php里写成./caddy/www:/var/www/html，显示not found

跟Nginx还是有点不同的，Nginx搭配php-fpm在Nginx的配置里配置/var/www/html所以在php容器里找/var/www/html，而和caddy搭配会在/usr/share/caddy里去找，所以找不到
