Who this Lab is for
Designed for
- Platform and DevOps engineers
- Developers configuring service accounts
- Security engineers auditing permissions
Use it when
- Creating new Role and RoleBinding resources
- Drafting ClusterRole definitions for operators
- Quickly assembling RBAC rules without writing raw YAML
A complete run, step by step
Select target identity
Choose whether the target is a User, Group, or ServiceAccount, and provide the name.
Define scope
Select Role for namespace-scoped permissions or ClusterRole for cluster-wide permissions.
Add permission rules
Specify API groups, resources, and toggle the required verbs for each rule block.
Copy the manifest
Review the dynamically generated YAML and copy it directly to your clipboard.
What you will need
Prepare the following information before starting. Use measured evidence where possible; defaults are examples and should not be treated as recommendations.
What the result tells you
Your report includes
- A complete, compliant Role or ClusterRole manifest
- A correctly linked RoleBinding or ClusterRoleBinding
- Manifests separated by standard YAML document markers
How it is determined
The generator binds user inputs into a structured template, automatically applying correct API groups, namespace requirements, and binding references based on the selected identity type and scope.
Structured YAML serialization and strict field validation prevent malformed or injected manifest content; authorization intent still requires human review.
Model assumptions
- • User requires standard Role and RoleBinding mapping.
- • Requested API groups, resources and verbs exist in the target cluster.
- • Least-privilege review is performed before applying the generated YAML.
Authoritative references
Namespace pod reader
Situation
A new service account needs to read pods in the 'default' namespace.
Result
The generator produces a Role allowing 'get', 'list', and 'watch' on 'pods', and a RoleBinding linking it to the specified ServiceAccount in the 'default' namespace.
Use the result with engineering judgement
- The tool generates raw manifests and does not apply them to a cluster.
- It does not validate if the specified API groups and resources exist in your cluster.
Questions before you begin
Does it support custom resources (CRDs)?
Yes. You can specify any API group and resource name in the rules section.
Can I generate a ClusterRoleBinding to a namespace Role?
No, the tool generates symmetric Role/RoleBinding or ClusterRole/ClusterRoleBinding pairs to prevent common misconfigurations.
Why do I need to supply the API group explicitly?
Kubernetes requires the API group for resources that are not in the core group (e.g. apps, batch). Explicitly providing it ensures valid manifests.
