Production RBAC & Security
Enforce Role-Based Access Control (RBAC) and NetworkPolicies to secure cluster resources and restrict unauthorized access.
1. RBAC Building Blocks (Roles & RoleBindings)
| Resource | Scope | Description |
|---|---|---|
Role | Namespace-level | Defines allowed API verbs (`get`, `list`, `watch`, `create`, `delete`) on specific resources within 1 namespace. |
ClusterRole | Cluster-wide | Defines allowed API permissions across all namespaces (or non-namespaced resources like Nodes/PVs). |
RoleBinding | Namespace-level | Binds a `Role` or `ClusterRole` to a user, group, or `ServiceAccount` in a specific namespace. |
ClusterRoleBinding | Cluster-wide | Grants permissions cluster-wide to subjects across every namespace. |
