Included review availability: Your plan includes up to 2 reviews per rolling hour; 1 remains after this review. 📝 WalkthroughWalkthroughThe operator adds optional telemetry configuration to the Jumpstarter API and CRD. It reconciles telemetry Deployments, Services, certificates, controller settings, and readiness status. Tests cover resource lifecycle, configuration, TLS, status, defaults, and helper behavior. ChangesTelemetry management
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds operator-managed telemetry resources and cleanup, but disabling telemetry may not reliably remove its Service because deletion occurs in the wrong reconciliation stage, and the RBAC checks do not confirm that the telemetry ServiceAccount receives no unintended permissions. Owner follow-up or explicit acceptance is needed before merge. Sequence Diagram(s)sequenceDiagram

Following up on a previous comment (the first one in this review). I think you could add an It block that enables telemetry with CertManager.Enabled: true, reconciles to verify the Certificate is created, then disables telemetry, reconciles again, and asserts the Certificate is absent if (big if) we want to delete the cert when to bool flag toggles to false.

Summary
Integrates the
jumpstarter-telemetryservice introduced in #930 into the Jumpstarter operator.Telemetry can now be configured through the
JumpstarterCR and is automatically deployed and managed by the operator, following the same patterns as the controller and router.What changed
Added telemetry Deployment and ClusterIP Service reconciliation, including cleanup when telemetry is disabled.
Added a new optional
spec.telemetryconfiguration with:enabledimage/imagePullPolicyreplicaslogging.filter.minSeverityresourcesAdded telemetry reconciliation to the main controller loop.
Configured the controller to advertise the telemetry endpoint to exporters through
GetServiceEndpoints.Added telemetry endpoint, certificate, and log filter configuration to the controller ConfigMap.
Added TLS certificate reconciliation through cert-manager, supporting both self-signed and external issuers.
Added a
TelemetryDeploymentReadystatus condition.Added integration and unit tests covering the telemetry lifecycle, replicas, TLS, configuration, probes, and status handling.
Usage
Telemetry can be enabled through the
JumpstarterCR:When enabled, the operator creates the telemetry Deployment and Service, configures TLS when cert-manager is enabled, and configures the controller to advertise the telemetry endpoint to exporters.
To disable telemetry and clean up its resources:
