Docker下pacman和yay无法连接网络

环境配置如下:

[~]$ cat /etc/pacman.d/mirrorlist
Server = https://mirror.sjtu.edu.cn/archlinux/$repo/os/$arch

[~]$ tail -n 2 /etc/pacman.conf
[archlinuxcn]
Include = /etc/pacman.d/archlinuxcn-mirrorlist

[~]$ cat /etc/pacman.d/archlinuxcn-mirrorlist
Server = https://mirrors.ustc.edu.cn/archlinuxcn/$arch

[~]$ echo $http_proxy
http://10.254.2.78:7890
[~]$ echo $https_proxy
http://10.254.2.78:7890

执行 sudo pacman -Syu 后，得到以下结果：

:: Synchronizing package databases...
 core downloading...

 archlinuxcn downloading...
error: failed retrieving file 'core.db' from mirror.sjtu.edu.cn : Failed to connect to mirror.sjtu.edu.cn port 443 after 10001 ms: Timeout was reached

怀疑sudo之后没有走代理，于是尝试 sudo -E pacman -Syu，一切正常。
su到root后 echo $http_proxy 确实没有代理，尝试在 /root/.bashrc 添加代理，source之后重新切回普通用户， sudo pacman -Syu 仍报同样的错误。
感觉问题更应该是docker的问题，但是docker小白，在网上搜寻未果，希望有大佬能帮忙解答或者给个搜索关键字。

sudo 默认会重置环境变量，可以配置 sudoers 来加上要保持的环境变量。
sudo 执行命令时不读 ~/.bashrc。

感谢大佬，问题已经解决了！
