Problem: one host, lots of VLANs. I need to import more than of these VLANs into a container. Unfortunately that does not work because --network-bridge=* can only be used once and --network-macvlan=* only works with physical interfaces (and does not support VLANs; also, hooking the whole interface to a container would be too insecure).
Solution: Please extend --network-veth and --network-bridge options, like --network-interface/macvlan, to be usable multiple times.
Let's continue tracking this on github:
