假设我们有一个使用 Django 构建的 Web 应用程序，它使用命令“ docker-compose up”作为 docker 部署。现在我们已经部署并运行了 Web 应用程序。

我们可以使用 IP:8001 访问该站点

我们如何使用 caddy 以 IP:80 访问该站点？

我做了什么：

install Caddy and verified it is running.

systemctl status caddy
● caddy.service - Caddy
   Loaded: loaded (/usr/lib/systemd/system/caddy.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2021-04-03 13:54:11 UTC; 3s ago

当访问 mydomain:80 时

您的网络服务器正在工作。现在让它为你工作。

Caddy is ready to serve your site over HTTPS:

Point your domain's A/AAAA DNS records at this machine.
Upload your site's files to /var/www/html.
Edit your Caddyfile at /etc/caddy/Caddyfile:
Replace :80 with your domain name
Change the site root to /var/www/html
Reload the configuration: systemctl reload caddy
Visit your site!

然后，我编辑了 /etc/caddy/Caddyfile: 如下

mydomain.com

# Set this path to your site's directory.
root * /usr/share/caddy  (I believe this should point to my volume of my docker web app. but I don't know how we can do that. any help is appreciated.   )

# Enable the static file server.
file_server

# Another common task is to set up a reverse proxy:
# reverse_proxy localhost:8080

# Or serve a PHP site through php-fpm:
# php_fastcgi localhost:9000

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile
  www.mydonmain.com {
    reverse_proxy 127.0.0.1:8001
}

api.mydonmain.com {
    reverse_proxy 127.0.0.1:8002
}

root * /usr/share/caddy
（我相信这应该指向我的 docker web 应用程序的卷。但我不知道我们如何做到这一点，因为 web 应用程序是使用 docker-compose 卷“运行”的。任何帮助表示赞赏。）

我的追求在哪里 systemctl status caddy
