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

First: thanks a lot for your answer!

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

I know, thanks. I should have mentioned that my docker compose sets up a user defined bridged network. the system defined networks are present.

The IP address of interface docker0 is selected by docker so that routing to and from the LAN physical network is possible

By LAN physical network you mean the tethered internet connection?

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.

I know but i think most of the setups similar to mine are running on a Pi. And i`m not familiar with the differences between PiOS and "out of the box" ubuntu.

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

I think i`m familar with the general concept of the docker network drivers.(but don`t know how and where to configure them)

Finally I think my question is: how can i setup a bridged network (in docker compose or portainer) to communicate with the network manager Hotspot instead of USB-Tether?
