I want to use docker for some experiments with software-defined networking, running emulators (which use pcap in promiscuous mode with their own IP stack) and the like. For this I need to connect containers to one or more bridge(s) without assigning them an IP address and gateway. I understand that…

You may be able to write your own network driver .

Hi Nathan, I don’t think that a network driver will work since the network plugin will always expect (and receive from docker) an IP address and gateway specification as part of the API (see here under “create network”: https://github.com/docker/libnetwork/blob/master/docs/remote.md ) If it would b…

Ah, too bad. Unfortunately I think this one’s a bit above my weight class, but @mavenugo might have some ideas.

Yes. With the current plugin specification, it isnt possible to omit IP Address. But with 1.11, we introduced a concept of --ipam-driver=nil. This will let the network plugin control the fate of container’s ip-address. I haven’t tried the case when the plugin deliberately omit the ip-address/gateway…

Any news on this topic? I really would like to be able to connect containers using pure L2 bridging/switching. I tried to use the ipam “null” driver but the network driver complains about empty ipv4 pool.

Hi, little late on chiming in on this, but I just got a random notification, so I wanted to throw out a couple of examples if they help. Example 1: docker network create -d macvlan \ --subnet=192.168.1.0/24 \ --gateway=192.168.1.1 \ -o parent=eth1 mcv1 docker run --net=mcv1 -it -…
