• 6.12-RC2 - Docker containers lost all network access

    I had a system lockup earlier and when it came back all my dockers had lost network access. I have network from unraid, I can ping/nslookup etc but from any docker container I cannot. I have a bridge with a 10gb connection, and 2 vlans I use in docker. 

     

    Edit 1: I’m reinstalling unraid. Will report back. Maybe some corruption on the flash drive, I don’t know what else would make docker networks randomly stop working. 
     

    Edit 2: I reinstalled and same issue so…maybe a freak switch issue?? 

    Edit 3: Oh and the hard lockup WAS macvlan related, I switched to ipvlan to remedy

    hard to tell from your config....are you using macvlan or ipvlan as network model in the main docker-service configuration (settings - dockker)? If macvlan, switch to ipvlan instead.

    I am using macvlan and switching to ipvlan doesn’t help…

    I fixed it...it was a 100% unrelated issue with a unifi switch, go figure.  I always say there are no coincidences....this was and I am ashamed to say it's resolved :)

    Can you share what you did to fix it? I am having the same issue and also have unifi equipment.

    Unifi introduced port profiles a long time ago and enabled blocking by default on some ports, I had upgraded my switches and didn't check the updated port profiles.
