How to specify network interface ?

[dceejay]

If I have a container with multiple internal networks - how do I specify which interface tc will attach itself to ? the README for the .loss alludes to the capability when it says "...outgoing from the chosen network interface"... so it must be possible - but there is no com.docker-tc. parameter for it.

Hi @dceejay,
I got the same issue, and didn't see in the code any way to choose an interface. So I made some changes (check the PR) to put traffic control over specific networks, note that if you have multiple interfaces on the same network it will not allow you to choose which interface.
At first I planned to add the capability to specify the eth0 or ethX interface but they are internal interfaces that docker do not known about. There is external interfaces name but I didn't see any way to know them beforehand.
I hope that it will be enough for your use case :)

sounds workable for me. Thanks
