Also note that eth0:1 isn't a vlan interface, it's simply an extra
address added to eth0 with an alias value of "eth0:1". So even if we did
have the phys or vlan interface types working with unprivileged
containers, they still wouldn't work with interface aliases.

In your case, I think you either want to put eth0 itself into a bridge
accessible to your containers or maybe do something with the macvlan
driver instead (though that latter won't work with unprivileged
containers).
