Networking and servers • Re: Docker/Nodered can't reach other devices on Hotspot-WiFi (NMCLI/Bookworm), No Router

Docker manages its own network unless you configure containers with network: host
Docker usually will create a docker0 network bridge device to let containers communicate with each other if necessary
The IP address of interface docker0 is selected by docker so that routing to and from the LAN physical network is possible
Firewalling rules are set by docker to let containers communicate with the physical network if necessary, e.g. containers masquerade under the IP address of bridge0

None of this is specific to Pi.

Maybe this can help. https://stackoverflow.com/a/43873743
