The question is about least privilege permissions “service account”. There are three Service accounts: fe frontend and frontend-default.
how do you know that one service account with least privilege permissions. Solution given was frontend-default sa is with least permissions. where as it is not used in any rolebindings.
How I checked.
k describe roles fe
it is bound to a fe rb.
k describe roles frontend
Similar out put.
But there is no rolebinding related to sa frontend-default.
Am I missing something here.
