Broadcasting from a docker container

Usually it is not possible to send UDP broadcasts from a docker container to the "outside world" if the container is not using host networking mode but the docker bridge. Using host networking mode might not possible or desirable for security reasons. As a workaround on Unix based host systems, it is possible to enable broadcast forwarding between the docker bridge and the bridged network interface. This script by dhutchison can be used to persistently enable broadcast forwarding for a specified docker network.

Example usage

The broadcast address needs to be specified explicitly for the broadcast to be routed correctly. Specify the brocast address for the network the machine to be waken up is part of.
