Docker network_mode: host - Why?

[AlbertoKarakoutev]

Could someone explain WHY this parameter is required? My docker compose config requires a network being setup with some network specific params, which I cant apply with the network_mode: host parameter. I want my containers to be logically separated from the host network and accessible to one another. HASS is running on my custom network and I want Music Assistant to do so as well. If someone could elaborate what exactly network_mode: host provides in this instance, I'd like to add that (ports and what not) manually so I can continue using my network.

because ports are dynamically opened/used and we rely on things like multicast for discovery.
There is an alternative to using host networking (which is even better imo) which is using a bridge/macvlan network.

In any case, the MA container needs full L2 access to the network

Thanks, I'll keep at it then with a network_mode: bridge
