我运行 `./launcher rebuild app` 失败，并收到以下输出信息：

```plaintext

```

我知道服务器无法访问 GitHub，因此已在 Docker 主机上设置了代理配置。  
我尝试过使用 `proxychains`，设置 `http_proxy` 环境变量以及 `git config`，但均无效。  
看起来 Docker 容器内部的命令在尝试从 GitHub 获取数据时并未使用代理。

请问是否可以通过代理安装或更新 Discourse？谢谢。

上次我做这件事大约是2017年，但大致内容如下：

> [@Install discourse with internet access only via proxy](https://meta.discourse.org/t/install-discourse-with-internet-access-only-via-proxy/66396/5?u=falco):
>
> This is possible, you need: Export http and https ENV variables in your current shell Add the same variables to the env block inside the containers/app.yml file Add the same variables to the docker system.d service config file (read system.d docs on this, you will need to create a new service file somewhere). After this, our official guide will work just fine.
