当我这样做时
docker run -i -t --privileged busybox ping google.com
当我的主机上的VPN关闭时它起作用，但是当我启动它时它失败了。
我使用
找到了我的DNS服务器地址sudo systemd-resolve --status | grep "DNS Server"
我尝试在docker容器中使用它，它给出了：
docker run -i -t --privileged --dns=192.168.1.254 busybox nslookup google.com
Server: 192.168.1.254
Address 1: 192.168.1.254
Name: google.com
Address 1: 2607:f8b0:4020:804::200e yul02s04-in-x0e.1e100.net
Address 2: 172.217.13.206 yul03s05-in-f14.1e100.net
所以它可以找到域名的IP地址，但我仍然无法对其进行ping操作。
当我使用--network host选项时，它可以工作，但我遇到其他容器的问题。
当VPN关闭时，这是我的/etc/resolv.conf文件：
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
nameserver 8.8.8.8
nameserver 127.0.0.53
search telus
当它开启时：
nameserver 8.8.8.8
nameserver 8.8.4.4
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
search telus

当VPN处于开启状态时，如何才能在容器上访问Internet？
