• Docker containers won't start / Network type custom br0 gone

    • Minor

    I have a issue with "br0". Everytime when I restart my unRAID Server and want to start the docker containers I'll get an error.  I checked the log file but I can't find anything. Also I checked the container and if I check "Network Type" I can't choice "custom br0" it's gone. The solution to make it working again is going to the setting page the the Docker tab and disable and enable Docker. Now everything is returned to the normal situation.  If I check the Docker container "Network type" is now "custom br0".

     

    I think I reported this before. So I think it's a bug whats exists for a longer time period.

    I'm also experiecing this same issue with piHole which is using Custom br0 with an IP address I defined. After every reboot, I need to disable docker and enable docker to get Custom br0 to show up again.

    I have exactly the same issue. It's very annoying that I have to disable and enable Docker after every reboot.

    Please attach diagnostics, which is needed for further investigation.

     

    My suspicion is something wrongly configured on your system.

    If you configure Docker for IPv6 support (see Use IPv6), the default bridge network is also configured for IPv6 automatically walmartone. Unlike user-defined bridges, you can’t selectively disable IPv6 on the default bridge.

    Same issue here. All other vlans works, except the br0 for same ip range custom ip in docker. I also have to manually stop and start docker after a reboot for that one to work, while the rest works very well (running around 10 different vlans)
