Add Kubernetes Users to Your Cluster
If you are working with Kubernetes a lot, you have probably built several basic clusters for learning purposes using kubeadm and the documentation here. As you start exploring topics like RBAC Roles and Pod Security Policies, you will soon notice that only one user was created in each cluster. And since that user has the cluster-admin role, it can do anything in any namespace. To try out many of the Kubernetes security-related concepts in your clusters, you will need to add Kubernetes users that are not cluster administrators. For your basic clusters, you probably don’t have integration set up with an external system to add and authenticate users. And as the Kubernetes docs note here: Kubernetes does not have objects which represent normal user accounts. Normal users cannot be added to a cluster through an API call.
This blog post will show you how to create new Kubernetes users in your clusters, focusing on clusters created using kubeadm.
