Rails 求助，docker 环境下，docker build 时报错，已经设置 ruby china gem 镜像地址
Retrying fetcher due to error (2/4): Bundler::HTTPError Could not fetch specs from https://gems.ruby-china.com/ due to underlying error <SocketError: Failed to open TCP connection to gems.ruby-china.com:443 (getaddrinfo: Temporary failure in name resolution) (https://gems.ruby-china.com/specs.4.8.gz)>
实际在浏览器中这个 specs 是可以下载的，但就是 docker compose build 的时候报错。 不知有哪位大佬遇到过这种情况？麻烦指点一下，谢谢。
