Thanks for reply , to check log with kubectl log will help when kube-api server is up . suppose i configured a file but path of file is not correct or some other issue because of that kube-api server not comes up . then where i can check log to identify the issue.

suppose I configured audit policy file and due to that kube api is not coming up so how i can identify the issue where i can check logs then

I know /var/log/pods/ inside that i can get log , but in mock exam, i am not getting that logs .

Please help , correct my understanding if anything wrong.
