Kubernetes Security, Part 1: Kubernetes Security Overview and Role Based Access Control (RBAC)

In this video, we will explore Kubernetes Role Based Access Control (RBAC) to provide fine-grain access to users and service accounts. We will start off by taking a quick look at Kubernetes overall authentication and authorization and will discuss some security best practices. We will then dive deep into RBAC, its architecture, and its tenants (Subjects, (Cluster)Role, and (Cluster)Bindings). In the demos, we will also discuss how to provision client certificates and create config files for new users and how to leverage RBAC to give them access to Kubernetes resources. We will also learn how to impersonate users in Kubernetes, a useful technique to ensure users have the right access to Kubernetes resources. Finally, we will discuss ClusterRole aggregation and go over built-in Kubernetes ClusterRoles.
