registry+v1: add APIService renderer support (OPRUN-4723) - #2885
Conversation
The registry+v1 bundle renderer had no generator for APIService objects
from csv.spec.apiservicedefinitions.owned. This meant operators exposing
extension APIs via aggregation could not be migrated to OLMv1 (C3 hard
block in the migration tool).
Changes:
generators.go:
- BundleCSVAPIServiceGenerator: reads csv.spec.apiservicedefinitions.owned
and emits an APIService object for each entry (group=desc.Group,
version=desc.Version, GroupPriorityMinimum=2000, VersionPriority=15,
service reference to the certProvisioner's service in install namespace).
CA bundle injected via the CertificateProvider in opts.
- BundleCSVDeploymentGenerator: extended to inject apiservice-cert volume
and volume mounts into deployments that serve APIServices, matching the
existing webhook-cert injection path.
- BundleDeploymentServiceResourceGenerator: extended to create Services
for APIService-serving deployments (matching the webhook service path).
validators/validator.go:
- CheckAPIServiceDeploymentReferentialIntegrity: validates that every
owned APIService references a deployment that exists in the CSV install
spec, preventing misconfigured bundles from being installed.
certproviders/certmanager.go, openshift_serviceca.go:
- Added *apiregistrationv1.APIService case to InjectCABundle so the
cert-manager and openshift-service-ca providers annotate APIService
objects for CA bundle injection.
registryv1.go:
- Registered BundleCSVAPIServiceGenerator and
CheckAPIServiceDeploymentReferentialIntegrity.
Tests:
- generators_test.go: 4 tests for BundleCSVAPIServiceGenerator covering
zero-owned case, single APIService, multiple APIServices, and empty
DeploymentName fallback port.
- registryv1_test.go: enumeration tests updated.
go.mod/go.sum: upgraded k8s.io/kube-aggregator v0.36.2→v0.36.3.
Once this merges, the C3 hard block is removed from the migration tool
(operators with APIService definitions become Eligible with no override).

📝 WalkthroughWalkthroughRegistryV1 now validates owned APIService deployment references and renders APIService resources with CA injection, authentication RBAC, deployment certificate volumes, and Service ports. Certificate providers support APIService annotations. Indirect module dependencies were added. ChangesOwned APIService rendering
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The PR adds APIService rendering and related resources, but the current head can still create APIService objects without a backend or generate rejected Services when APIs share a deployment with webhooks, preventing extension APIs from becoming available. Merge should wait for these validation and Service-port fixes; the dependency declaration is a minor follow-up. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

🌐 Web query:
For Kubernetes v1.36, what validation applies when a Service defines two TCP ServicePort entries with the same name and port but different targetPort values?
💡 Result:
In Kubernetes v1.36, defining two TCP ServicePort entries in the same Service with the same name and the same port is invalid [1][2]. Kubernetes imposes the following validation rules on the Service spec: 1. Unique Names: All ports within a ServiceSpec must have unique names [1][2]. Providing two ServicePort entries with the same name will cause validation to fail [1][2]. 2. Unique Port/Protocol Pairs: While the official API documentation for the Service object specifies that the ports array uses a merge strategy based on the port key [1][2], Kubernetes validation logic prevents the creation or update of a Service that contains multiple entries with the same port and protocol [3][4]. Because these rules require both the name and the port/protocol combination to be unique within a Service, any attempt to define two TCP ServicePort entries sharing both the same name and the same port will be rejected by the API server [1][3]. Even if the targetPort values differ, the violation of the unique name and unique port/protocol constraints will prevent the Service from being created or updated [1][2][3].

Prevent conflicting Service ports for a shared deployment.
If a webhook uses 443 -> 8443 and an owned APIService uses 443 -> 443 on the same deployment, both entries remain in sets.Set[corev1.ServicePort]. The generated Service contains duplicate port name 443 and duplicate TCP 443/TCP entries, so Kubernetes rejects it. Validate the conflict or allocate distinct Service ports before rendering.

Reject empty DeploymentName values for owned APIServices.
An empty value currently passes referential-integrity validation, while deployment and Service generation skips that definition. The rendered APIService then has no generated backend Service. Enforce the required field, retain the missing-deployment error, and add coverage for both cases.

Summary
The registry+v1 bundle renderer had no generator for
APIServiceobjects fromcsv.spec.apiservicedefinitions.owned. This meant operators that expose extension APIs via Kubernetes API aggregation could not be migrated from OLMv0 to OLMv1 (C3 hard block in the migration tool).This PR adds full parity with OLMv0's

CA bundle injection via annotation is supported by cert-manager for APIService objects.
Downstream effect: Once merged, the C3 hard block is removed from the OLMv0→OLMv1 migration tool (library-olm) — operators with owned APIService definitions become Eligible with no override flag required.
