Namespaces & RBAC

Summary

Namespaces logically partition a cluster (e.g. by team or environment); Role-Based Access Control governs who can do what within those namespaces — both essential for multi-team cluster safety.

• 1Create a namespace and deploy a resource into it, rather than the default namespace.
• 2Define a basic Role and RoleBinding restricting a user to read-only access in one namespace.
• 3Learn why namespace isolation alone isn't security — RBAC is what actually enforces access limits.
