oran-o2ims: fix timing issue in TLS scan after tls-13 rollout - #84290
Conversation
The tls-13 step applies the Modern TLS profile with StrictAllComponents, triggering a full cluster rollout (~20 min). In some cases, service-ca restarts and re-issues serving certificates before tls-scanner-run begins, causing operator pods to still be restarting. The scanner then finds ports open but no TLS active, reporting NO_TLS for affected endpoints (e.g. 125/133 instead of 133/133). Add a new wait-for-tls-pods-post-rollout step between tls-13 and tls-scanner-run to ensure pods are fully ready and serving TLS after the cluster rollout. The step reuses the existing wait-for-tls-pods commands script via symlink to avoid duplication. Applied to install-bundle-tls-scan and install-bundle-tls-scan-periodic in both main and release-4.22 configs. Co-authored-by: Cursor <cursoragent@cursor.com>

It does not add logging statements or log passwords, tokens, API keys, PII, session IDs, hostnames, or customer data. The new post-rollout symlink targets the existing wait script, which reports service names, selectors, pod status, events, and secret names, but not secret contents. The ACM setup script referenced by the added configuration contains test MinIO credentials in applied manifests, but its here-document is not logged and no credential values are echoed.

The oran-o2ims alarms-server and controller-manager pods crash-loop on vanilla OCP clusters without ACM: alarms-server fatally exits when it cannot resolve alertmanager.open-cluster-management-observability.svc, and controller-manager exits after a 2-minute cache sync timeout for missing ACM CRDs (ManagedCluster, ClusterInstance, Policy, ImageBasedGroupUpgrade). Adding the acm-install chain before the operator install ensures these dependencies are present so all endpoints can be scanned. Co-authored-by: Cursor <cursoragent@cursor.com>

…ndency The alarms-server pod fatally exits when it cannot reach alertmanager.open-cluster-management-observability.svc:9095, which is only available after ACM Observability (MultiClusterObservability CR) is deployed. Add rhobs-acm-setup-observability after acm-install to deploy MinIO + MCO + Alertmanager so the alarms-server can start successfully and expose its TLS endpoints for scanning.

[Comment authored by Cursor] @coderabbitai The Container-Privileges finding refers to the MinIO Deployment in the existing rhobs-acm-setup-observability step (ci-operator/step-registry/rhobs/acm-setup-observability/), which is maintained by the RHOBS/COO team. Our PR does not create or modify that step — we only reference it with - ref: rhobs-acm-setup-observability. The step is already used in production by other jobs (e.g. rhobs-observability-operator-main__amd64-ocp-4.21-azure). Fixing the MinIO security context should be addressed upstream by the RHOBS team in a separate change, not in this PR. |

The fix worked exactly as intended: all TLS-capable endpoints passed with TLS 1.3 + ML-KEM with two NO_TLS endpoints for probes: hardwaremanager-server:8081 and controller-manager:8081. /unhold |

Summary
Fix intermittent TLS scan failures in
install-bundle-tls-scanandinstall-bundle-tls-scan-periodicjobs foropenshift-kni/oran-o2ims(bothmainandrelease-4.22).Problem
The
tls-13step applies the Modern TLS profile withStrictAllComponents, which triggers a full cluster rollout (kube-apiserver, openshift-apiserver, etcd, service-ca, etc. — ~20 minutes). In some cases, theservice-caoperator restarts during this rollout and re-issues serving certificates, causing our operator's pods to be killed and recreated with new TLS certs.The
tls-scanner-runstep runs immediately aftertls-13completes but only waits for clusteroperators to stabilize — it does not wait for our operator's pods to come back up and serve TLS. The scanner then finds ports open but no TLS active, reportingNO_TLSfor the affected endpoints.Additionally, on vanilla OCP clusters without ACM, the
alarms-serverpod fatally exits when it cannot resolvealertmanager.open-cluster-management-observability.svc, and thecontroller-managerexits after a 2-minute cache sync timeout for missing ACM CRDs (ManagedCluster,ClusterInstance,Policy,ImageBasedGroupUpgrade). These crash-looping pods were another source ofNO_TLSreports.Evidence from prow job 2093172179674861568:
oran-o2ims-wait-for-tls-pods(beforetls-13): all pods Running 1/1, all TLS secrets presenttls-13: 20-minute rollout, service-ca restarted, pods recreated (different pod instance names in scanner CSV vs wait step)tls-scanner-runCSV:controller-manager:6443NO_TLS,controller-manager:9443NO_TLS,alarms-server:8443NO_TLSFix
Add ACM dependencies: Install ACM (
acm-installchain) and ACM Observability (rhobs-acm-setup-observability) before the operator install, soalarms-servercan resolve its Alertmanager dependency andcontroller-managercan sync its ACM CRD caches.Add post-rollout wait step: Insert a new
oran-o2ims-wait-for-tls-pods-post-rolloutstep betweentls-13andtls-scanner-runto ensure our operator's pods are fully ready and serving TLS after the cluster rollout before the scanner runs.The test sequence changes from:
to:
Why a separate step instead of reusing the same ref?
ci-operator enforces unique step names within a multi-stage test (validation source). Using
- ref: oran-o2ims-wait-for-tls-podstwice produces:This is a fundamental constraint in how ci-operator tracks step execution and artifacts.
The new step's commands script is a symlink to the original
oran-o2ims-wait-for-tls-pods-commands.sh, so there is zero code duplication — one script, two step names.Changes
