It seems to me that .local is reserved for purposes within a local network, not necessarily local to an individual computer itself. You could, for example, set up an internal server on your network and have it resolve with storage.local. You could argue that a collection of containers is basically the same thing, though.

If a container has its own IP address, I think it can be considered its own device on the network, regardless of the details.
