AuthzRoleBinding

An AuthzRoleBinding connects a subject (identified by a JWT claim-value pair) to one or more roles within a namespace. Each role mapping can optionally narrow the binding's scope to a specific project or component within the resource hierarchy.

Resource Definition

Metadata

AuthzRoleBindings are namespace-scoped resources.

apiVersion: openchoreo.dev/v1alpha1
kind: AuthzRoleBinding
metadata:
  name: <binding-name>
  namespace: <namespace>

Spec Fields

Field	Type	Required	Default	Description
entitlement	EntitlementClaim	Yes	-	Subject identification from JWT claims
roleMappings	RoleMapping[]	Yes	-	List of role-scope pairs this binding grants
effect	string	No	allow	allow or deny

EntitlementClaim

Field	Type	Required	Description
claim	string	Yes	JWT claim name (e.g., groups, sub, email)
value	string	Yes	JWT claim value to match (e.g., dev-team)

RoleMapping

Each entry in the roleMappings array pairs a role reference with an optional scope.

Field	Type	Required	Description
roleRef	RoleRef	Yes	Reference to the role to bind
scope	TargetScope	No	Narrows the mapping to a specific project or component. Omit for namespace-wide

RoleRef

Field	Type	Required	Description
kind	string	Yes	AuthzRole (same namespace) or ClusterAuthzRole
name	string	Yes	Name of the role to bind

TargetScope

All fields are optional. Omitted fields mean "all" at that level.

Field	Type	Required	Description
project	string	No	Scope to a specific project within the namespace
component	string	No	Scope to a specific component (requires project)

important

scope.component requires scope.project to be set. This is enforced by a validation rule on the resource.
