How do I add a new human User to Kubernetes? Is there a `kubectl create user` command?

Surprisingly, no. Kubernetes does not have a native 'User' API object for humans. It relies on external identity providers. If you are on AWS EKS, human authentication is handled by AWS IAM. If you use a raw cluster, it is often handled by OpenID Connect (OIDC) via providers like Auth0, Google, or Dex.

What is a ClusterRoleBinding?

A `RoleBinding` grants permissions within a specific namespace. A `ClusterRoleBinding` grants permissions across the *entire* cluster, ignoring namespace boundaries. Giving a user a ClusterRoleBinding tied to the `cluster-admin` ClusterRole gives them God Mode over the entire system.
