It looks to me that the kernel version on the node01 in the k8s 1.23 playground is not compatible with Apparmor:
root@node01 ~ ➜ apparmor_parser -q apparmor-profile
Cache read/write disabled: interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.)
Warning: unable to find a suitable fs in /proc/mounts, is it mounted?
Use --subdomainfs to override.
root@node01 ~ 
uname -r
5.4.0-1080-gcp
Can you please confirm or correct me if i am wrong? Any workaround is appreciated.
