Using Docker on Mac Mini

[simoncn]

I found this explanation in the Docker help pages:

Limitations

Processes inside the container cannot bind to the IP addresses of the host because the container has no direct access to the interfaces of the host.

The host network feature of Docker Desktop works on layer 4. This means that unlike with Docker on Linux, network protocols that operate below TCP or UDP are not supported.

MinimServer (and all UPnP servers) uses SSDP and IGMP discovery, as required by the UPnP protocol. From the above, it appears that these lower-level protocols are not supported by Docker on macOS.
