运行Docker容器时主机上无网络 [英] No network on host machine when running a Docker container

问题描述

我在Arch Linux计算机上，使用以下命令运行容器时主机上没有网络:

I'm on Arch Linux machine, and have no network on the host when running a container with this command:

docker run jenkins

停止Docker之后，网络又恢复了. 任何建议都非常受欢迎.

After stopping the Docker the network is back again. Any suggestions are more than welcome.

似乎在使用-p选项运行并提供80以外的其他端口时，网络可用了几分钟，然后又丢失了.

It seems that when running with -p option and providing some other port than 80, the network is available for a few minutes, and then it gets lost again.
