This is more of a general Docker question but one that I’d think maybe someone else here has encountered - Docker seems to have issues with bridging UDP multicast from host network to the internal docker network. I’ve seen resin commits on the nodejs mdns project so I’m wondering if someone from Resin knows how to solve this.
Use case: My resin-based product needs to detect other (third-party, non-resin) hardware on the local network. Using standard mDNS/ DNS-SD this is relatively straightforward.
However the Docker way of creating a private bridge network + exposed ports doesn’t work with UDP multicast and thus far I haven’t been able to figure out brctl or iptables rules to get this to work. Do you just run the container in host mode networking instead? Thx.
