无法从 https://rubygems.org/ 下载数据 - Net::OpenTimeout: execution expired

wget 可以正常下载 rubygems，网络连接也正常。

如果主机上的互联网连接正常，您需要调试该主机上 Docker 容器内的互联网连接。

Can't build container, no clear errors

The real problem is this one: If the server/container can’t access the Discourse source code in GitHub it won’t be able to build/update. Since you said it works on the host, you need to debug the container networking. Drop to a similar container shell with docker run --it debian:buster-slim bash and debug from there.
