Kubernetes rbac Generator

The Kubernetes RBAC Generator scaffolds strict Role and RoleBinding manifests. It enforces least-privilege access control for users and service accounts.

How it Works

1

Define Rules - Select the specific API groups, resources, and verbs (get, list, create) to permit.

2

Assign Subjects - Bind the role to a specific ServiceAccount, User, or Group.

3

Generate YAML - Export the rbac.authorization.k8s.io/v1 manifest.

Best Practices

Secure clusters require granular Role creation and explicit Subject bindings.

Permissions

Cluster-admin wildcard

Explicit verbs on specific resources

Scope

ClusterRole

Namespace-scoped Role

Subject

Default service account

Dedicated, named ServiceAccount

Example Output

Here is a real generated snippet matching the production best practices above:

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: pod-reader

Advanced Configuration Logic

Cluster security relies entirely on Role-Based Access Control. Granting cluster-admin rights to applications is a critical vulnerability. Writing granular RBAC rules requires knowing the exact API groups and verb arrays. Our tool visually constructs these rules, ensuring applications only receive the exact permissions they need (least privilege), preventing privilege escalation attacks within the cluster.
