Walkthrough

The changes update Helm chart templates for OpenFGA by enhancing label management. Two standard Kubernetes labels are added to the common labels template. Label inclusion in the deployment template is consolidated, and labels are now added to Role and RoleBinding resources in the RBAC template. No logic or public interface changes occurred.

50-50: Label addition: app.kubernetes.io/component
Added the standard component label with a fixed value. Consider quoting static strings (e.g. "authorization-controller") for YAML consistency and to avoid parsing edge cases.

---

55-55: Label addition: app.kubernetes.io/part-of
Introduced the part-of label to tie resources back to the OpenFGA chart. Ensure this new label is documented in your chart’s README so users are aware of the automatically applied metadata.

charts/openfga/templates/rbac.yaml (2)

6-7: Apply consolidated labels to Role resource
The openfga.labels helper is correctly injected under metadata.labels with proper indentation (nindent 4). This ensures all standard and custom common labels propagate to Roles.

---

21-22: Apply consolidated labels to RoleBinding resource
Consistently applying openfga.labels to RoleBindings aligns with the rest of the chart. Indentation and scope look correct.

charts/openfga/templates/deployment.yaml (1)

28-28: Consolidate pod labels using openfga.labels
Replacing separate selector/common labels with a single openfga.labels inclusion simplifies maintenance. The nindent 8 is correct and podExtraLabels still applies as expected.
