Secure Access in Kubernetes with ServiceAccounts and RBAC

Description

This lab demonstrates how to implement secure access control in Kubernetes using ServiceAccounts and Role-Based Access Control (RBAC). I created custom ServiceAccounts, assigned them limited permissions using both Roles and ClusterRoles, and linked them using RoleBindings and ClusterRoleBindings. The access was tested to verify both namespace-level and cluster-wide permissions.

Tools and Technologies

• Kubernetes
• RBAC
• ServiceAccounts
• YAML
