Cyborg has an agent that runs on compute nodes to manage accelerator
devices. Add a default dataplane service definition so that cyborg can
be included in the dataplane nodeset services list without users having
to create the service manually.

Details
Needs approval from an approver in each of these files:
Added Cyborg service management to OpenStack control planes, including configuration, API route and TLS settings, readiness reporting, and container image selection.
Added Cyborg as a data-plane service.
Expanded data-plane configuration documentation, including execution settings, service ordering, and status details.
Documentation
Updated node-set examples with Ansible execution environment resource settings.
The operator now supports Cyborg configuration and reconciliation in OpenStackControlPlane, including image selection, endpoint and TLS settings, and readiness reporting. The pull request also updates data-plane resource documentation and examples.
Changes: Cyborg control-plane integration
Layer / File(s)
Summary
Cyborg configuration and validation api/core/v1beta1/*, api/bases/core.openstack.org_openstackcontrolplanes.yaml, config/crd/bases/core.openstack.org_openstackcontrolplanes.yaml
The control-plane API and CRD define Cyborg configuration and readiness conditions. Webhook validation and defaulting handle service dependencies, templates, and API route TLS overrides.
The version API, CRDs, and image selection logic include Cyborg API, agent, and conductor images. Default image variables and image matching include Cyborg.
Cyborg reconciliation and wiring cmd/main.go, internal/openstack/cyborg.go, internal/controller/core/openstackcontrolplane_controller.go, config/rbac/role.yaml, config/services/dataplane_v1beta1_openstackdataplaneservice_cyborg.yaml
The controller reconciles and watches Cyborg resources. Reconciliation manages credentials, endpoint and TLS settings, resource updates, and control-plane readiness and image status.
Tests cover Cyborg defaults, TLS, endpoints, readiness, image status, and topology references. Test setup and fixtures register and configure Cyborg.
Data-plane resource documentation
Layer / File(s)
Summary
Execution settings and status documentation docs/assemblies/dataplane_resources.adoc, docs/assemblies/ref_example-OpenStackDataPlaneNodeSet-CR-for-*.adoc
The resource documentation adds execution summary, status, dependency, image-type, and execution-environment details. Two examples specify execution-environment resource requests and limits.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
GetContainerImages uses each non-nil custom Cyborg image pointer even when it points to an empty string. The new optional string fields and shown CRD schemas impose no nonempty constraint, so an empty custom value may replace a usable default image.
A Cyborg child workload may receive an empty image and fail to start instead of using its configured default.
This can occur when: An OpenStackVersion specifies customContainerImages.cyborgAPIImage: "", cyborgAgentImage: "", or cyborgConductorImage: "".

- Around line 2800-2803: Update the Cyborg credential lifetime validation in the
control-plane schema to compare effective values after defaults are applied,
including the 364-day default grace period when gracePeriodDays is omitted.
Reject admission when the effective grace period is not smaller than the
effective expirationDays value, while preserving the existing validation for
explicitly supplied values.
Review comments at @api/core/v1beta1/openstackcontrolplane_webhook.go:
- Around line 364-367: Update the Cyborg validation branch to require a usable
Placement service when Cyborg is enabled, including when Nova is disabled;
reject configurations without an enabled or externally configured Placement
endpoint. Preserve the existing Galera, RabbitMQ, and Keystone checks, and reuse
the established Placement validation and endpoint symbols.
- Around line 498-499: Update the enabled-Cyborg validation paths for both
create and update to handle a nil Spec.Cyborg.Template before calling
ValidateCreate or its update-validation counterpart. Skip template validation
when it is absent and preserve existing validation behavior when it is present.
Review comments at @docs/assemblies/dataplane_resources.adoc:
- Line 329: Update the `osImageType` reference in the dataplane resources
documentation to mark the field as optional, not required; preserve its
documented CRD default of `uefi`.
Review comments at @internal/openstack/cyborg.go:
- Around line 235-236: In the Cyborg condition mirroring path, update the
readiness handling so Cyborg is marked running when ObservedGeneration differs
from Generation, rather than mirroring a stale Ready=True condition. Preserve
the existing mirroring behavior once the current generation has been observed.
- Around line 124-125: Update the pod-level TLS handling around
`instance.Spec.TLS.PodLevel.Enabled` so copying generated Cyborg TLS state does
not overwrite the requested public certificate secret. Keep the requested secret
separate from generated certificate state and preserve it for Cyborg’s public
service when no route is used.
- Around line 199-200: Before dereferencing cyborg.Spec.Secret, initialize it
from instance.Spec.Secret when it is nil; preserve the existing assignment
behavior when it is already non-nil so reconciliation can proceed without a
panic.

If Cyborg sets expirationDays: 2 without overriding the default grace period, the merged grace period is 364 days. Keystone rejects the credential, so provisioning fails. Validate the merged values during control-plane admission.
