- Minor
I had this issue with the betas, and now with 7.0.0 RC,
On many of my docker containers I had br0 selected for Network Type, and a set IP Address.
After updating from 6.12.13 none of the Docker containers start up.
The containers say br0 in the container list in the Network Column, but when I click through to the settings for each one, the Network Type dropdown has changed to None. Br0 is missing, I see Bridge, Host, Container, None. Bridge gets the container a 172.x IP, none of the options have the field to set the container IP.
Suggested troubleshooting steps included stopping the Array and then going into Network Settings and turning off Bridging, saving, turning bridging on, saving and starting array, then see if the option for br0 and the field for the IP appeared in the container settings. No luck.
I see under the network settings under Routing Table that br0's do in fact exist.
Edit:
I was looking in the log and saw something about my IPv6 DHCP being invalid

This was not an issue in Unraid 6.12.*, I changed the IP to d00 and it started working. Still the chances that docker can be broken by 7.0.0 upgrades is not ideal.
