networking - Multicast with Docker Swarm and overlay network -


i testing application using multicast discovery. created swarm cluster , network create -d overlay swarm-net containers share same lan across several swarm agents hosts.

the discovery seemed not working, installed tshark. tshark shows ip address node within tshark running , multicast address packet being sent though tshark does not show incoming multicast packet.

note that, don't know better way so, container run --privileged enable tshark. note containers can communicate each other.

is multicast blocked because of docker iptable? how enable multicast in overlay network?

overlay-driver network does not support multicast uses vxlan unicast, according chanwit (and experience far).

note plugin weave net (an overlay network driver) does support multicast!
