Launch containers into specific overlay networks subnets


(Brian Bianco) #1

I’ve created an overlay network and I’d like for different docker daemons on different hosts to use unique subnets.

E.G. host1 uses 192.168.1.0/24 and host 2’s containers are launched into 192.168.2.0/24.

Does anybody know how to do this? I can easily launch containers on different hosts into the overlay network but they all use the 192.168.1.0 subnet.

Does this involve configuration at the docker-daemon level? Maybe --fixed-cidr? Or when creating a container is there a flag used in conjunction with --net=my_net?
