如何使用代理 `./launcher rebuild app`

[Falco]

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

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.
