从Docker容器中获取主机的Mac地址 [英] Get Mac-Address of Host from within Docker Container

问题描述

在我的Docker化应用程序中，我需要具有硬件锚点并考虑使用Container的Mac地址.但是:由于Docker容器的Mac地址是可变的，并且在容器启动时动态分配，因此我无法使用此Mac地址(请参阅 Docker文档)

In my dockerized application I need to have a hardware anchor and thought about using the Container's Mac-Address. But: since the Mac-Address of a Docker container ist volatile and dynamically assigned at container startup I cannot use this Mac-Address (see Docker docs)

MAC地址是使用分配给IP地址的IP地址生成的.容器，以避免ARP冲突，使用范围为02:42:ac:11:00:00到02:42:ac:11:ff:ff

The MAC address is generated using the IP address allocated to the container to avoid ARP collisions, using a range from 02:42:ac:11:00:00 to 02:42:ac:11:ff:ff

Docker主机的Mac地址将是一个可行的解决方案.

The Mac-Address of the Docker host would be a viable solution.

如何从在此主机上运行的容器中访问(linux)主机的Mac地址?

How can I access the (linux) host's Mac-Address from within a container running on this host?

推荐答案

启动时，您可以将Mac地址作为环境变量传递给容器

You can pass the mac address to the container as an env variable when starting it

docker run -e mac=$(ip link show eth0 | awk '/ether/ {print $2}') alpine env
