Inline comments:
In
`@control-plane-operator/controllers/awsprivatelink/awsprivatelink_controller.go`:
- Around line 924-932: Guard both Route53 zone-creation paths in
control-plane-operator/controllers/awsprivatelink/awsprivatelink_controller.go:924-932
and :1357-1362 before accessing CloudProviderConfig.VPC. Return a wrapped error
when AWS or CloudProviderConfig is nil in the hypershift.local path; in the
private-ingress path, return an error and set the managed-DNS condition to
False. Reuse the existing controller flow and preserve normal zone creation when
the configuration is present.
- Around line 1369-1390: Move the ACME CNAME creation using CreateRecord outside
the IngressPublicZoneID-empty branch so it runs on every reconcile after a valid
zone ID is available. Keep public zone creation, tagging, and status assignment
conditional on an empty IngressPublicZoneID, and retain the existing error
condition and return handling for CreateRecord.
- Around line 1439-1449: Update setManagedDNSCondition to persist status using
an optimistic-concurrency patch from a deep copy, and return any write error
instead of only logging it. Propagate that error through every caller, including
the successful DNS reconciliation path, so failures are returned rather than
converted to a successful RequeueAfter result. Ensure the patch preserves both
DNSZones and the managed DNS condition while avoiding overwrites of concurrent
status updates.
- Around line 1506-1515: The dnsEndpoint mutation in the AWS PrivateLink
reconciliation flow writes recordTTL as float64, causing type mismatches and
repeated updates; change the recordTTL value in the Object["spec"] construction
to int64(300), leaving the surrounding endpoint fields unchanged.
In `@control-plane-operator/controllers/awsprivatelink/route53.go`:
- Around line 176-180: Update lookupZoneID and its controller call site to
accept and use vpcID and region, querying ListHostedZonesByVPC for both the
initial lookup and conflict handling so only the requested VPC’s private zone is
selected. Add a regression test covering a same-name private zone associated
with a different VPC.
- Around line 326-355: Update the Route 53 deletion flow around changes and
ChangeResourceRecordSets to partition records into batches of at most 1,000
ResourceRecord elements and 32,000 value characters, submit each batch
sequentially, and wait for each change request to reach INSYNC before proceeding
or returning for hosted-zone deletion. Preserve skipping SOA/NS records and add
coverage for multiple batches and pending changes.
In `@control-plane-operator/controllers/hostedcontrolplane/v2/kas/deployment.go`:
- Around line 402-406: Update applyAWSIAMAuthenticatorContainer to resolve the
aws-iam-authenticator image through the release image provider or supported HCP
image override instead of hard-coding the public ECR image, while preserving the
existing container configuration.
In `@control-plane-operator/controllers/hostedcontrolplane/v2/kas/oauth.go`:
- Around line 101-123: Add unit tests for generateAWSIAMAuthWebhookConfig
covering both IAM authenticator enabled and disabled annotation paths; verify
the generated kubeconfig’s server URL, current context, and
InsecureSkipTLSVerify setting, while preserving the expected behavior when the
feature is disabled.
In `@hypershift-operator/controllers/hostedcluster/hostedcluster_controller.go`:
- Around line 1434-1454: Make AWSIAMAuthConfigSync a hard prerequisite for the
IAM authenticator path: if fetching or reconciling aws-iam-auth-config fails,
stop propagation and all downstream handling of the
hypershift.openshift.io/aws-iam-authenticator annotation so the sidecar is not
enabled. Update the surrounding reconciliation flow, not just the report.execute
severity, to gate the core HCP chain on successful ConfigMap sync.
- Line 820: Update the condition list in the HostedCluster status reconciliation
to append hyperv1.AWSManagedDNSAvailable only when hcluster.Spec.Platform.Type
equals hyperv1.AWSPlatform; leave non-AWS HostedClusters without this
AWS-specific condition.

Add opt-in, CPO-managed Route53 ingress DNS for AWS HostedClusters, gated
by the AWSManagedDNS feature gate (TechPreviewNoUpgrade) and enabled per
cluster via spec.platform.aws.managedDNS.
When enabled the control-plane-operator:
- creates public and private Route53 ingress zones
({ingressDomainPrefix}.{baseDomain}, prefix is required) in the
customer account; the private zone is skipped for shared-VPC clusters,
which reuse the VPC owner's zone;
- records zones in status.platform.aws.dnsZones and mirrors the
AWSManagedDNSAvailable condition to the HostedCluster;
- overrides dns.config public/private zones so the ingress operator
creates wildcard *.apps records in the managed zones;
- optionally (spec.platform.aws.managedDNS.delegation) creates an ACME
DNS01 challenge CNAME and performs NS delegation, either via a
DNSEndpoint CR consumed by external-dns (ExternalDNS mode) or by
exposing zone nameservers in status for the platform (Manual mode);
- recreates zones deleted out-of-band and cleans them up on deletion.
Supporting changes:
- extract the generic Route53 helpers from the awsprivatelink controller
into support/awsutil so both controllers share one implementation;
- grant the CPO the Route53 hosted-zone permissions it now needs and let
the delegating client implement them;
- extend externaldns dnsendpoints RBAC and external-dns --source=crd to
the AWS provider (previously GCP-only).

The control-plane-operator policy granted hosted-zone create/delete/tag and record access on all hosted zones for every CLI-created cluster, regardless of whether managed ingress DNS was requested. Gate the wider permissions on the --managed-dns option, mirroring the ingress operator policy. Without it, record access is scoped to the cluster's local zone again and shared-VPC clusters get no Route53 access, matching the behavior before managed DNS was introduced. The delegating client keeps the managed-DNS superset of CPO Route53 APIs, so the generated client is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
CreatePrivateHostedZone reused the first private zone matching the requested name, without checking its VPC association. Route53 allows same-name private zones on other VPCs, so a cluster could adopt, write records into, and on teardown drain and delete another owner's zone. Look up candidate zones by name, then use GetHostedZone to return only the one associated with the cluster VPC and region, both before creating and after a create conflict. Route53 does not allow a VPC to be associated with two private zones of the same name, so at most one zone can match, and a concurrent create resolves to the same zone. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Changing spec.platform.aws.managedDNS.ingressDomainPrefix after the zones were created was accepted by the API but could not converge: the controller kept the old zone, relabeled it in status with the new name and switched the apps domain to a name the zone does not serve. Make ingressDomainPrefix immutable, and add a feature-gate-aware rule on AWSPlatformSpec so managedDNS cannot be added to or removed from an existing cluster, which would otherwise bypass the immutability.

Summary
Adds opt-in, CPO-managed Route53 ingress DNS for AWS hosted control planes, behind the
AWSManagedDNSfeature gate (TechPreviewNoUpgrade). Opt in per cluster by settingspec.platform.aws.managedDNSon the HostedCluster.Implements the managed ingress DNS design from openshift/enhancements#2079.
When enabled, the control-plane-operator:
Creates Route53 ingress zones. A public zone always, plus a private zone for standard (non-shared-VPC) clusters, named
{ingressDomainPrefix}.{baseDomain}(ingressDomainPrefixis required whenmanagedDNSis set). Shared-VPC clusters reuse the VPC owner's private zone rather than creating their own.Reports zones in status.
status.platform.aws.dnsZonesrecords each zone's ID, type, name, and nameservers, and theAWSManagedDNSAvailablecondition is surfaced on the HostedCluster.Wires up the ingress operator. Overrides
dns.configpublic/private zones with the managed zone IDs so the ingress operator creates wildcard*.appsrecords in them.Handles NS delegation when
spec.platform.aws.managedDNS.delegationis set. The CPO creates the ACME DNS01 challenge CNAME in the public zone for cert issuance, then delegates the zone's nameservers:ExternalDNS: creates aDNSEndpointCR that external-dns uses to write NS records into the parent zone.Manual: exposes the zone nameservers in status for the consuming platform to delegate.When
delegationis omitted, the CPO only creates the zones and reports them ready.Self-heals and cleans up. Recreates zones deleted out-of-band, and drains and deletes the managed zones on HostedCluster deletion (best-effort for permission errors and already-deleted zones).
Design notes
HostedControlPlane.status.platform.aws.dnsZones, HCCO reads HCP status and setsdns.configpublic/private zones, then the ingress operator creates the wildcard records.infrastructure.config, notdns.config, so noplatform.type: AWSis set indns.config. Setting it forces an unnecessary STS:AssumeRole path that breaks the ingress operator.API
spec.platform.aws.managedDNSis an optional struct gated by theAWSManagedDNSfeature gate. Enabling managed ingress DNS is opt-in per cluster.managedDNSis set,ingressDomainPrefixis required (1-63 chars, DNS label). There is no server-side default, so settingmanagedDNS: {}is rejected. The CLI passesinas the ingress subdomain.Supporting changes
