I recently tried to create an aditional user in my Kubernetes Cluster. Therefore I searched for hours to find nothing.
With this post I’d like to help you find the solution quicker .
First of, there are no “User” like in LDAP or Active Directory in Kubernetes (K8s). This is just another name for a Serviceaccount (SA). Those Serviceaccounts are bound to a particular Namespace (NS). Unfortunately both User and Serviceaccount are mixed pretty good by Kubernetes.
