docker-compose up -d

注意一点 /data/caddy/Caddyfile 需要提前创建好

Caddyfile

Caddy有两种配置格式：1. json 2. Caddyfile，由于Caddyfile较为简洁，因此选用了这种方式。

Example

localhost

respond "Hello, world!"

静态内容

your_domain {
    root * /var/www
    file_server
}

反向代理

your_domain {
    reverse_proxy your_server_ip:port
}

Compare
