OpenWrt VLANs and Docker


I'm sure I'm missing something simple here and was hoping someone might be kind enough to give the old grey matter a nudge in the right direction.

I have installed docker, dockerd and docker-compose on 23.05.

I have a 3 port device, 1 WAN and 2 LAN. The 2 LANs are in br-lan with VLAN filtering and all are tagged.

Docker installs a default interface called Docker, a bridge called docker0 and a veth device.

When I try to restart the Docker interface, it says 'Error: Network device is not present'

I have no communication with docker containers, but the subnet does respond to ping from the ash shell

I'm surmising that the VLAN filtering maybe part of the problem, but I do not understand the 'Error: Network device is not present' message. Can someone help me figure out A) what's causing that error and B) how I can have the docker0 bridge communicate with the VLAN br-lan bridge, please?
