Recent randomized per-namespace osp-secret passwords change (openstack-k8s-operators/ci-framework#4114) broke leaf operators that still authenticated to central Keystone as admin.

Apply leafAdminUser and leafAdminProject from skmo-values to the leaf OSCP KeystoneAPI template and align manual deployment docs with the admin-two model.

📝 Summary

Summary by CodeRabbit

  • Documentation

    • Updated multi-namespace setup guidance with the default leaf-region admin identity: admin-two.
    • Clarified that the configured leaf admin user is created in central Keystone and receives project-level and system-wide admin roles.
    • Documented use of the existing central admin project and clarified credential key defaults and sourcing from the leaf secret.
  • Configuration

    • Added mappings for leaf admin credentials and service users.
    • Added configurable Octavia and Swift service users.
    • Updated Glance and Swift authentication to use the configured service account names.

Walkthrough

The leaf-region setup now creates the configured leaf admin user in central Keystone and grants project-level and system-wide admin roles. Kustomize passes admin and service-user values to leaf services. Documentation records the defaults and password configuration.

Changes

Leaf Identity Configuration

Layer / File(s) Summary
Leaf admin identity flow
examples/va/multi-namespace-skmo/control-plane.md, examples/va/multi-namespace-skmo/control-plane2/kustomization.yaml
The setup uses the configured leafAdminUser and leafAdminProject, assigns project-level and system-wide admin roles, and maps the admin credentials to the leaf KeystoneAPI.
Leaf service-user wiring
examples/va/multi-namespace-skmo/control-plane2/kustomization.yaml, examples/va/multi-namespace-skmo/control-plane2/service-values.yaml, examples/va/multi-namespace-skmo/control-plane2/skmo-values.yaml
Kustomize maps service-user values to the service templates. Octavia and Swift receive leaf-specific values. Glance uses the configured service-user template instead of a fixed username.
Identity configuration documentation
examples/va/multi-namespace-skmo/README.md
The README documents the admin-two and admin defaults, the password key, Kustomize targets, and leaf service-user wiring.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to a7a9e

The leaf identity and service-user configuration aligns across the documented values, Kustomize wiring, and service templates, so no merge-blocking risk is identified.

🟠 Major · Propagate leafAdminPasswordKey to passwordSelectors.admin.

examples/va/multi-namespace-skmo/control-plane2/kustomization.yaml:94-115
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Propagate leafAdminPasswordKey to passwordSelectors.admin. The setup uses the configured key when creating the leaf user in central Keystone. The leaf KeystoneAPI defaults to AdminPassword. If the selected key contains a different value, leaf authentication fails.

Add this replacement after leafAdminProject:

Leaf and central regions share one Keystone but get different passwords
when ci-framework randomizes per-namespace osp-secret keys. The leaf OSCP
must register region-prefixed service users (regionTwo_nova, etc.) in
central Keystone; default names (nova, placement) collide with the
central region's users and cause HTTP 401 at runtime.

`skmo-values.yaml` already defined `serviceUser*` keys but kustomize never
applied them to the OpenStackControlPlane. Add replacements for all
enabled leaf services, including octavia and swift which were omitted
from the original six AC-enabled services but are deployed in this VA.

Also fix Glance's Swift backend config to use service:{{ .ServiceUser }}
instead of hardcoded service:glance so object-store auth matches the
renamed leaf glance service user.
