To search quickly for content in the OpenShift logs across all pods and namespaces, enter a debug shell and grep in /var/log. This can be a handy way to search for errors when you're not quite sure what's going on with your application, you've already examined pods and events to no avail, and you don't know where to turn. Be warned, though, the output may be voluminous, so it helps to have some clue what you're looking for.
$ oc debug node/crc-vsqrt-master-0
Starting pod/crc-vsqrt-master-0-debug ...
To use host binaries, run `chroot /host`
If you don't see a command prompt, try pressing enter.
sh-4.2# chroot /host
sh-4.4# cd /var/log
sh-4.4# grep -r mypodname .
