如果希望容器能够修改主机的网络配置,则需要将–net = host选项传递给docker run.从docker-run(1)手册页：

--net="bridge"
   Set the Network mode for the container
       'bridge': creates a new network stack for the container on the docker bridge
       'none': no networking for this container
       'container:': reuses another container network stack
       'host':  use  the host network stack inside the container.
       Note: the host mode gives the container full access to
       local system services such as D-bus and is therefore
       considered insecure.

您需要同时运行–privileged和–net = host.
