📝 WalkthroughWalkthroughThe chart now derives NodeWright resource names, labels, webhook Service references, and RBAC names from Helm helpers. The operator discovers webhook configurations by label and Service, updates all matching configurations, checks readiness, and remints certificates when the Service changes. CRDs remain during rollback or uninstall. Generated manifests and Chainsaw tests cover rendering, upgrades, admission, cleanup, and compatibility. Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟠 High · up to This PR renames webhook resources and changes upgrade and certificate-reconciliation behavior. At the current head, one webhook update failure can prevent the other webhook from receiving its CA bundle, and deployment paths that omit the service-name setting may still mint certificates for the old Service; the new cluster-mutating test also lacks its required CI pool assignment. These create concrete admission and validation risks, so the PR is not merge-ready until addressed or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Reviewed statically — read the full diff and the surrounding files; did not build or run anything.
The three operator-side changes are correctly motivated, and finding them by actually running chart/v0.17.1 -> branch on kind rather than by reading is the right way to have gotten here. The cert-remint-on-Service-change fix in particular is the kind of thing only a real upgrade surfaces.
Five things above nit level. Three are inline; two are on lines this PR doesn't touch, so they're here.
1. docs/metrics/prometheus_values.yaml:36 — the shipped scrape config stops matching, silently
- source_labels: [__meta_kubernetes_service_name]
action: keep
regex: skyhook-operator-controller-manager-metrics-serviceThis PR renames that Service to nodewright-controller-manager-metrics-service (chart/templates/metrics-service.yaml, and it's row 4 of your own before/after table). A keep relabel that matches nothing yields zero targets and no error — the first signal a user gets is an empty dashboard, with nothing in the operator logs, Prometheus logs, or helm upgrade output pointing at the cause.
The file isn't in this PR's diff, which is why I can't anchor this inline, but it's a file the rename has to touch. Line 18's comment (The Prometheus ServiceAccount must be bound to skyhook-operator-metrics-reader) wants the new name too, or at least the deprecation note.
2. docs/metrics/README.md:239 — the file now contradicts itself
Line 93 (which this PR adds) correctly says skyhook-operator-metrics-reader is deprecated and tells the reader to re-point bindings at nodewright-metrics-reader. Line 239, down in the Prometheus section, still says:
…and bind the Prometheus ServiceAccount to
skyhook-operator-metrics-reader, as shown in the local dashboard setup above.
"as shown above" is no longer what's shown above — the block at line 89 now uses nodewright-metrics-reader. Since the deprecation alias is the one thing here users are expected to act on themselves, the two mentions disagreeing is worse than either one alone.
Not findings, flagging so they don't get re-litigated:
- CodeRabbit's
operator/Makefile:339comment is wrong.rollout-localtargets the Helm-installed Deployment, andchart.selectorLabelsrendersapp.kubernetes.io/name: nodewright. Your change fixes a stale value; it should not be reverted tocontrol-plane=controller-manageralone. docs/designs/webhook-bootstrap-lease.md:143-149keeping the pre-rename object names is right, and the note explaining they're the v0.7.x-era names plus the label-based equivalent handles it well.helm-template-test/chainsaw-test.yaml:184-207renders under--set fullnameOverride=skyhook-operator, so theskyhook-operator-*strings there are intentional override coverage.- CLI contract is unaffected —
operator/internal/cli/utils/utils.go:538discovers the operator bycontrol-plane=controller-manager, not by name. Worth one line in the description saying so, sinceCLAUDE.mdasks for an explicit justification when a rename crosses a contract surface.
Also confirmed this merges cleanly with #462 — git merge-tree auto-resolves all five shared files. Both edit docs/metrics/README.md though, and finding #2 above sits in a region #462 also rewrites, so whichever lands second is worth a full re-read of that file rather than trusting the auto-merge.

Re-reviewed against aed7bfa1.
All five of my earlier findings are addressed. Worth calling out that on the manager-rbac.yaml resourceNames question you took the harder option — kept least privilege and backed the invariant with a helm-template-test assertion, rather than widening the grant as I'd leaned toward. That's the better call and my stated preference was wrong on the merits. The readiness check went further than I asked for too: the per-webhook dialsThisOperator filter is a real improvement over just looping.
Two new findings below, both of which I'd want resolved before merge:
- The unconditional
skyhook-operator-metrics-readeralias collides with the templated ClusterRole underfullnameOverride: skyhook-operator— the exact overrideRELEASE_NOTES.md:55recommends as the admission-gap mitigation. I rendered it: two ClusterRoles, same name,helm installfails. The documented workaround can't be executed. - #464 is fixed for the nodewright CRDs only. The legacy
skyhook.nvidia.compair is also chart-managed undertemplates/, didn't getkeep, and still cascade-deletes on rollback or uninstall. The comment's stated rationale is inverted — the conversionclientConfigis on the legacy pair, not the two files carrying the annotation — which is probably how the gap arose.
I'm filing these as comments rather than a formal block; the severity call is yours.
Four further findings I verified but haven't posted, happy to add any on request: CheckOrUpdateWebhookConfigurations still returns on the first error so a validating-side failure defers all mutating caBundle injection; the WEBHOOK_SERVICE_NAME probe in selector-migration-job.yaml negates grep's exit status rather than kubectl's, so a transient API failure deletes the live Deployment; and dialsThisOperator introduces a new Service-name coupling that reproduces the bootstrap-lease deadlock shape if webhook.serviceName or fullnameOverride changes on a running release — a different axis from the one this PR fixes, and one the selectorMigration shim doesn't cover since it only detects the env var's absence, not a change to it.
Context on how I checked: rendered the chart under several value combinations, traced the label-discovery path, and confirmed the anchors against the diff. I did not run a cluster, so the deadlock chain in that last item is reasoned rather than observed.
The manager and leader-election RBAC, the metrics reader ClusterRole, both Services, and both webhook configurations were still named skyhook-operator-*, along with the app.kubernetes.io/created-by and part-of labels. They now template off chart.fullname the way the Deployment already did, and operator/config/ is mirrored (namePrefix: nodewright-), so kustomize and Helm render identical names. Closes #440. Renaming the webhook Service and the two webhook configurations turned out not to be a chart-only change. Three things had to move with it: The operator finds its webhook configurations by the nodewright.nvidia.com/webhook-config label instead of by name. A name-based lookup makes a rename a hard error on the running old leader: it never goes Ready, so the rolling update never terminates it, so it never releases the webhook bootstrap lease, and helm upgrade wedges on "Pending termination". The now-vestigial webhookValidatingWebhookConfiguration / webhookMutatingWebhookConfiguration builders and webhookClient are removed with the constants; the chart has owned creation of these objects for several releases and the operator only ever patched their caBundle. The webhook serving certificate is reminted when the Service is renamed. Secret/webhook-cert is operator-owned, so it survives the upgrade, and the operator only reminted on expiry or a cert-on-disk mismatch. A renamed Service therefore left a year-valid cert carrying the old SAN and admission failed closed with "x509: certificate is valid for skyhook-operator-webhook-service..., not nodewright-webhook-service". Label discovery cannot save the upgrade that introduces it, because the pod holding the lease is the pre-rename one. The existing selectorMigration pre-upgrade hook now also detects a pre-label-discovery operator (the live Deployment has no WEBHOOK_SERVICE_NAME env var) and deletes the Deployment so Helm recreates it. It stays a no-op on normal upgrades. Two latent bugs on the same surface, fixed in passing: - The chart never passed WEBHOOK_SERVICE_NAME or WEBHOOK_SECRET_NAME, so the operator silently ignored webhook.serviceName and webhook.secretName. - The manager ClusterRole granted no delete on the webhook configurations, so the pre-delete cleanup job's kubectl delete was RBAC-denied and the trailing `|| true` swallowed it. The job now also sweeps the pre-rename names, since an orphaned failurePolicy: Fail configuration rejects every matching API call cluster-wide. skyhook-operator-metrics-reader is kept as a deprecated duplicate ClusterRole: docs/metrics/README.md tells users to bind their own Prometheus ServiceAccount to it by name, so renaming it alone would break their scrape with no error anywhere else. Also fixes #464, found by manual validation of the same migration: the CRDs live in templates/ (they interpolate the conversion-webhook Service name) so helm manages them as release resources, and `helm rollback` to a pre-rename revision deleted nodewrights.nodewright.nvidia.com, cascade-deleting every NodeWright. Both nodewright CRDs now carry helm.sh/resource-policy: keep, which suppresses deletion only -- create and patch on upgrade are unaffected, so schema changes still apply. Two consequences: uninstall now leaves the CRDs behind, and a kept CRD keeps its meta.helm.sh/release-name, so reinstalling under a DIFFERENT release name fails with "invalid ownership metadata" until they are deleted. That second one bites the helm chainsaw suite, which shares one namespace across five release names, so uninstall-helm-chart.sh drops the CRDs on teardown -- keeping them is a production guarantee, not a test-fixture one. Verified on kind, chart/v0.17.1 to this branch: the upgrade completes hands-off, the cert is reminted, the caBundle lands on the renamed configurations, admission rejects for the right reason rather than on TLS, only the intentional metrics-reader alias survives, and helm uninstall leaves no orphans. Covered by a new helm-upgrade-rename-test that installs the pre-rename chart from its git tag (same mechanism as k8s-tests/migration, so no registry dependency) and round-trips a rollback; with the annotation reverted that step fails with the CRD "not found", so it is not a vacuous guard.

Pushed 1. You were right that the alias collided with the templated ClusterRole under Two objects of the same kind and name in one release is a silent overwrite, not an error. I first guarded it with It is now a plain rename: re-point the binding at Also added a general guard so this class cannot come back: 2. Legacy CRDs and CI is running; the only thing I did not re-run locally before pushing is the upgrade e2e, which is a test-assertion risk rather than a product one. |
The namespaced Role and RoleBinding added with the Jobs migration were copied from helmify output that predates the rename, so they hardcoded skyhook-operator-manager-role and -manager-namespaced-rolebinding while every other name in the chart goes through chart.fullname. The resource-names-follow-fullname guard added in #463 catches exactly this and failed helm-tests. Mirrored the stale created-by/part-of labels in the kustomize source, which kustomize namePrefix already handled. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>

The controller-manager Deployment name andspec.selectorare unchanged, so #285 does not recur; every renamed object is created new and the old one removed, and none has an immutable field a rename would trip.Why this isn't chart-only
Renaming the webhook Service and the two webhook configurations required three operator-side changes. All three were found by actually running
chart/v0.17.1 → this branchon kind, not by reading.1. The rollout deadlocks. The pre-#440 operator looks its webhook configurations up by name. Renaming them makes it hard-error, so it never goes Ready, so the rolling update never terminates it, so it never releases the webhook bootstrap lease.
helm upgradewedges onPending terminationand the release stays stuck:The operator now finds them by the
nodewright.nvidia.com/webhook-configlabel (filtered to configurations whoseclientConfigtargets its own namespace) and patches every match, so future renames are invisible to it.docs/designs/webhook-bootstrap-lease.mdgains a section on why a name-based lookup is specifically forbidden here.Label discovery cannot save the upgrade that introduces it, because the pod holding the lease is the pre-rename one. The existing
selectorMigrationpre-upgrade hook now also detects a pre-label-discovery operator — the live Deployment has noWEBHOOK_SERVICE_NAMEenv var — and deletes the Deployment so Helm recreates it. Verified to stay a no-op on normal upgrades.2. The serving cert kept the old SAN.
Secret/webhook-certis operator-owned, not chart-owned, so it survives the upgrade, and the operator only reminted on expiry or a cert-on-disk mismatch. A renamed Service left a year-valid certificate carrying the old DNS name and admission failed closed:It now also remints when the Service recorded on the Secret no longer matches the configured
WEBHOOK_SERVICE_NAME.3. The chart never passed the env vars.
WEBHOOK_SERVICE_NAMEandWEBHOOK_SECRET_NAMEalready existed on the operator but nothing set them, sowebhook.serviceNameandwebhook.secretNameinvalues.yamlwere silently ignored.Also fixed in passing
The manager ClusterRole granted only
get/updateon the webhook configurations, so the pre-delete cleanup job'skubectl delete ...webhookconfigurationwas RBAC-denied and the trailing|| trueswallowed the error.deleteis now granted, and the job also sweeps the pre-rename names — an orphanedfailurePolicy: Failconfiguration with no operator behind it rejects every matching API call cluster-wide.Also fixes #464:
helm rollbackdestroyed every NodeWrightThe CRDs live under
templates/(they interpolate the conversion-webhook Service name), so Helm manages them as release resources. Rolling back to a pre-rename revision droppednodewrights.nodewright.nvidia.comfrom the rendered manifest and Helm deleted it, cascade-deleting everyNodeWrightobject. Both nodewright CRDs now carryhelm.sh/resource-policy: keep.keepsuppresses deletion only — Helm still creates and patches these CRDs on install and upgrade, so schema changes apply exactly as before. Two consequences, both inchart/RELEASE_NOTES.md:helm uninstallnow leaves the two CRDs behind. Delete them explicitly for a full teardown.meta.helm.sh/release-name. Reinstalling under the same release name adopts it; under a different name Helm fails withinvalid ownership metadata. Verified both on kind.That second consequence bites our own helm chainsaw suite, which shares one namespace across five release names (
events-rbac,foobar,node-affinity-test,nodewright,webhooks), so the first uninstall would have broken every later install.uninstall-helm-chart.shnow drops the CRDs on teardown — keeping them is a production guarantee, not a test-fixture one. All seven helm tests pass in a single run against one cluster.The new
helm-upgrade-rename-testround-trips ahelm rollbackand asserts both CRDs survive. With the annotation reverted that step fails withactual resource not found, so it is not a vacuous guard.Also caught while rebasing:
docs/metrics/prometheus_values.yamlrelabels on the metrics Service name, which this PR renames, so the shipped example scrape job would have silently matched zero targets. Its regex now accepts both names, and its namespace list coversnodewrightas well asskyhook.Deprecation, not removal
skyhook-operator-metrics-readerships as a duplicate ClusterRole for a deprecation window. Unlike every other renamed object it is a name users bind to themselves:docs/metrics/README.mdtells them to create a ClusterRoleBinding against it for their Prometheus service account, so renaming it alone would break their scrape with no error anywhere else. Removal is a follow-up.New patterns introduced
Per
CLAUDE.md, calling these out explicitly:webhookValidatingWebhookConfiguration/webhookMutatingWebhookConfiguration/webhookClient. These became dead once the name constants went away. The chart has owned creation of these objects for several releases; the operator only ever patched their caBundle, and the error messages already said so.helm-upgrade-rename-testmaterializeschart/v0.17.1withgit archive, the same mechanismk8s-tests/migration/lib.shuses, so there is no registry dependency — buthelm-testsnow needs full history with tags, which the CItestsjob already sets. Noted indocs/ci-test-pools.md.CLI contract: unaffected
CLAUDE.mdasks for an explicit justification when a change touches a contract surface, so stating it rather than leaving it implied: this rename does not cross the CLI contract.The CLI discovers the operator by label, not by name —
operator/internal/cli/utils/utils.gousesLabelSelector: "control-plane=controller-manager", and its own comment notes that label is the one "which both the chart and the kustomize overlay label". Nothing underoperator/cmd/cli/oroperator/internal/cli/references any of the renamed objects (grepforskyhook-operator,metrics-reader,*-webhook-service,*-manager-rolereturns no non-test hits). The annotation keys, status fields, and finalizer names the CLI depends on are untouched.No CLI change, no version gate, and no
docs/cli.mdcompatibility-matrix entry is needed.Verification

Written up in
chart/RELEASE_NOTES.md: this chart requires an operator built from this PR or later, the controller-manager Deployment is deleted and recreated on the one upgrade that crosses the rename, there is a brief admission gap while the operator injects the caBundle into the newly created configurations, andskyhook-operator-metrics-readeris deprecated. Releases that pinfullnameOverride/nameOverridekeep their own prefix on everything and are unaffected.
