You will learn to: Understand foundational Kubernetes security concepts, including authentication and authorization flows; Configure kubectl with kubeconfig files to securely connect individual users to the cluster; Create and manage Roles, ClusterRoles, RoleBindings, and ClusterRoleBindings; Implement the principle of least privilege to restrict user permissions safely; Explore modern authentication patterns, including token-based access and OIDC integration basics; Test and verify user permissions using built-in Kubernetes diagnostic commands. You will start with essential security terminology and the Kubernetes API access lifecycle, then progress to written configuration scenarios and permission validation. This course is designed for DevOps beginners, system administrators, and developers looking to secure their Kubernetes environments, with no prior cluster administration experience required.
