Docker related interfaces (br-xxxxxxxxxxxx)
-
Docker creates interfaces for containers on the kernel level. So you can troubleshoot the majority of it on the kernel (data plane) rather than the docker level (control plane)
-
Check the kernel’s view of network interfaces
-
ip link show
-
If its there, see if its up
-
ip link show br-xxxxxxxxxxxx
-
Check the kernel logs for the interface name to see any events
-
journalctl -k | grep br-xxxxxxxxxxxxx
-
For more info you can check docker logs for events also within a certain time period (wont show network interface logs)
-
journalctl -u docker —since “00:00” —until “00:10”
