I am having issues after a reboot (sudo reboot), the network does not come back online. The only way to resolve this is by unplugging and reinserting the ethernet cable.
I recently posted on the Raspberry Pi Forums and after some testing, it was suggested that it appears there is conflict between the host and docker.
I did try adding denyinterfaces veth* to the beginning of /etc/dhcpcd.conf but did not work.
The last post suggested issues with docker firewall config issues. Anyone know how I test and fix these issues?
Expected Results: When rebooting, the network recovers and do not need to unplug + reinsert the ethernet cable.
I have been investigating this further and after extensive testing, it appears my issue is isolated to the bridge network / containers. I removed the bridge containers, kept the host ones and the Pi seems to successfully boot every time.
Anyone know how I go about fixing the bridge ones?
At first, I though it must be a subnet clashing but I have changed the default subnet a couple of times now and the issue is still persistent.
I also tried a few commands to try and reset the network adapters when the system failed to start with no luck. Commands used
sudo ifdown eth0
sudo ifup eth0 (also tried docker0)
