145-162: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
ModeSinglenow runs the validator twice, but the outer budget still assumes one run.
cpRCandgpuRCboth setClusterValidatorin theModeSinglebranch, and the twoRunPreflightForRolecalls at Line 482 and Line 483 are sequential. EachrunClusterValidatorinvocation owns a 5-minuteclusterValidatorTimeout, so the worst case is 10 minutes plus RBAC bootstrap and log fetch.outerTimeoutis 6 minutes. The compute-plane validator then derivesvctxfrom the remaining ceiling and its wait is truncated, which is the exact failure the comment at Line 155 sets out to prevent.Two related effects in the same path: the second run calls
sweepPriorClusterValidatorJobs, which deletes the control-plane Job, so--no-cleanupcannot preserve it for debugging.Size the budget for the number of validator runs.

resolveStackValuesFiledepends on the operator's working directory and a fixed environment name.The function walks up from
os.Getwd()fordeploy/stacks/self-managed/environments/local.yaml. Two limits follow:
- An installed CLI run outside the source tree never finds the file, so
global.image.registrynever contributes a registry entry.- The path pins the
localenvironment. An operator running a staging or production environment file gets no registry from this source.Add a flag or Viper key for the values file, and use this walk only as the fallback.

Inline comments:
In `@src/clis/nvcf-cli/cmd/self_hosted_check_test.go`:
- Around line 390-448: Update TestCheck_ComputePlaneFlagRunsChecks and
TestCheck_ControlPlaneFlagRunsChecks to run with --skip-cluster-validation, and
set NVCF_CLI_SELFHOSTED_SKIP_INOTIFY via t.Setenv in each test. Preserve the
existing JSONL parsing and category assertions.
In `@src/clis/nvcf-cli/cmd/self_hosted_check.go`:
- Around line 200-207: Update the registry credential setup block to run
whenever !localOnly, removing the clusterValidatorImage non-empty condition.
Continue obtaining extraRegistries and stackValuesFile, and pass the possibly
empty clusterValidatorImage to selfhosted.EnumerateRegistries so
global.image.registry and configured extras are checked independently of the
validator image.
In `@src/clis/nvcf-cli/internal/selfhosted/clustervalidator.go`:
- Around line 210-225: Confirm the validator’s namespace-wide write requirements
by tracing the operations used by the validator binary, especially namespace,
pod, service, and network-policy checks. If writes only target the probe
namespace, replace the cluster-wide permissions with namespace-scoped
Role/RoleBinding access while retaining required cluster-wide read permissions;
otherwise, add cleanup in the --cleanup flow to delete the validator ClusterRole
and ClusterRoleBinding after the run.
- Around line 145-150: Preserve the error from ensureClusterValidatorConfig in
the control-plane path instead of assigning it to _. Store a non-fatal config
note and append it to cleaned before every ClusterValidatorResult return, or
otherwise expose it through the result transcript, while retaining the wrapped
error context and continuing validation.
In `@src/clis/nvcf-cli/internal/selfhosted/preflight.go`:
- Around line 348-353: Ensure the registry-credentials category is constructed
and executed only once per command invocation, rather than once for each role
passed to RunPreflightForRole. Update buildCategories or the cmd-layer
orchestration around RunPreflightForRole to gate registry handling to a single
role/invocation while preserving all other role-specific categories and result
emission.
- Around line 687-690: Update the stale-namespace message construction around
r.Message to emit remediation hints per stale reason rather than one blanket
kubectl delete command. For “stuck Terminating,” direct operators to remove
namespace finalizers; for “no Helm release,” provide a cautious
inspection/removal hint that does not imply force-deleting the namespace.
Preserve the stale namespace names and counts in the output.
In `@src/clis/nvcf-cli/internal/selfhosted/registry_cred.go`:
- Around line 172-178: The registry endpoint parsing must preserve non-default
ports and correctly handle IPv6 and trailing-colon inputs. In
src/clis/nvcf-cli/internal/selfhosted/registry_cred.go lines 172-178, update the
extras handling around parseRegistryHostPort so RegistryEntry.Registry retains
the parsed port when it is not 443, allowing probeRegistryCredential to use the
correct URL. In src/clis/nvcf-cli/internal/selfhosted/clustervalidator.go lines
386-408, replace the manual parsing in parseRegistryHostPort with
net.SplitHostPort and strconv.Atoi, and add table cases covering [::1]:5000 and
nvcr.io:.
- Around line 95-108: The probeRegistryCredential flow must require configured
credentials for critical registry entries before accepting a successful
exchangeBearerToken result. Check credentialsForRegistry and the entry’s
critical status before returning success, while preserving the existing
rejected-credentials error for configured credentials and the anonymous-token
behavior for non-critical entries.
In `@src/clis/nvcf-cli/internal/selfhosted/stale_namespace.go`:
- Around line 103-111: Update the Secret List call in the stale namespace check
to set ListOptions.Limit to 1, since only existence is required. Add a concise
comment documenting that this check assumes Helm’s default secret storage driver
and may report namespaces using configmap or SQL storage as having no Helm
release.
In `@src/clis/nvcf-cli/internal/selfhosted/validatortag.go`:
- Around line 334-343: Trim whitespace from unquoted parameter values in the
parsing branch of the validator, before assigning or using val. Preserve the
existing comma splitting and empty-params behavior, while ensuring values such
as service after a comma are passed without leading spaces.
- Around line 218-229: Validate the realm URL before applying credentials in the
request flow around credentialsForRegistry: parse the realm and reject it unless
it uses HTTPS and has an acceptable host for the registry authentication
endpoint. Ensure this validation occurs before req.SetBasicAuth, so credentials
are never sent to HTTP or unrelated hosts.

VALIDATOR_ROLE is a dead env var — nothing reads it, so this whole feature inverts into a guaranteed failure on every healthy control plane.
grep -rn VALIDATOR_ROLE outside src/clis/nvcf-cli returns nothing. nvca/cmd/cluster-validator/main.go reads only VALIDATOR_CONFIG_NAMESPACE / _NAME / _PREFLIGHT / _SUMMARY_NAMESPACE and calls clustervalidator.Run(ctx, client, configNS, configName, summaryNS, emitMetrics) — no role argument. The RoleControlPlane / RoleComputePlane constants that preflight.go:268-272 says this "must match" do not exist in that package.
So the Job runs the unchanged GPU-centric check set. validator.go:164-165 unconditionally runs checkGPUResources / checkGPUOperator, and printSummary marks {state.GPUAvailable, "GPU Resources: Available", ..., true} Critical. check --control-plane (or --pre / --all in ModeSingle) therefore schedules a Job on a GPU-less control plane, the Job exits non-zero, clusterValidatorCheck maps Passed=false to severity "error" (preflight.go:601), anyFailed trips, and the command exits 2. Unconditionally.
None of the advertised Gateway API / LB / node-to-node checks exist in the shipped binary either — yet the ClusterRole at L230 grants cluster-wide create/delete on services and daemonsets, pods/log get, and gateway.networking.k8s.io read, with inline comments justifying probes that grep proves absent.
This PR is only correct if #781 (which adds the role parameter and the control-plane check set) merges first. Worth making that dependency explicit in the PR description and, ideally, landing them together.
There was a problem hiding this comment.
Agreed on the ordering; the two PRs are planned to merge together. #781 reads VALIDATOR_ROLE and prints a Validator role line, and until an image with that support is published, a control-plane run whose transcript has no role line but does have the GPU Resources section is reported as a warning that the image predates roles, not as a failed control plane (fbe7599, 178461e, TestClusterValidatorCheck_PreRoleImageIsAWarning). A role-aware image that fails, or a transcript with neither marker, still fails the run. The ClusterRole is trimmed to what the #781 checks call: Services are read-only, pods/log and watch are gone, and DaemonSet create/delete stays for the node-to-node probe (047d62c, TestEnsureClusterValidatorRBAC_LeastPrivilege).

Limit: 1 + len(Items) == 0 is not a valid "nothing matched" test — the apiserver contract explicitly forbids this inference.
From the vendored metav1.ListOptions.Limit godoc (apimachinery types.go:375-382): "Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available."
Namespace nvcf on a healthy install holds dozens of Secrets (SA tokens, TLS, pull secrets) that sort before sh.helm.release.v1.*. The first page scans a non-matching object, returns Items=[] plus a Continue token, and this code concludes "no Helm release". The ConfigMap fallback at L117-120 then hits kube-root-ca.crt (auto-created in every namespace since 1.21) and does the same.
Result: nvcf: no Helm release at error severity, check exits 2, and the remediation tells the operator to kubectl delete namespace nvcf on a live install. ListMeta.Continue is never read anywhere in this file.
Fix: either drop Limit entirely, or loop on Continue until Items is non-empty or Continue == "".
There was a problem hiding this comment.
The probe now follows the Continue token until it finds an owner=helm object or the server reports no more pages, with a 1000-page cap so it always terminates (b8faf70, ce9f770). TestProbeStaleNamespaces_PagesPastNonMatchingObjects pins it with an empty first page that carries a Continue token. A namespace with no Helm release is now also a warning with an inspect command rather than an error with a delete command (bb0d56b, e5ab3dd).

Both lists are wrong in ways that produce error-severity false positives with destructive remediation. Verified against deploy/stacks/self-managed/helmfile.d/ and deploy/stacks/nvcf-compute-plane/helmfile.d/:
nvcf-backendnever hosts a Helm release. It is created at runtime by NVCA (clusteragent/k8s_maintainer.go:51,defaultRequestsNamespace), andself_hosted_down.go:544already states "Workers are operator-managed pods, not a separate helm release." It is on the control-plane list, so in ModeSingle a healthy cluster with running functions reportsnvcf-backend (no Helm release)at error severity, exits 2, and printskubectl delete namespace nvcf-backend— which destroys every live worker.nvca-systemis the same shape on the compute list: operator-created, no release. The only compute-plane release isnvca-operatorin nsnvca-operator.openbao-systemdoes not exist.openbao-serverdeploys tovault-system(01-dependencies.yaml.gotmpl:59-62) — which is already in the list.cert-manager(01-dependencies:53-56) andnvcf-ui(02-core:202-205) are real stack namespaces that are never probed, so acert-managernamespace stuck Terminating silently passes.envoy-gateway-systemis hardcoded while the chart templates{{ .Values.ingress.gatewayApi.controllerNamespace }}(base.yaml:394, default"").
The same false-positive shape hits vault-system / cassandra-system / nats-system whenever they are pre-created by the operator or installed via Argo CD rather than helmfile.
Altitude note: this is now the 5th copy of the NVCF namespace set in this CLI (clusterdump.ControlPlaneNamespaces, self_hosted_up.go:87, pullsecret.go:56, defaultDownReleases) and it already disagrees with all of them. Given the blast radius of the remediation string, deriving from the helmfile release list rather than hardcoding seems worth the effort.
There was a problem hiding this comment.
The static lists now hold only namespaces a helmfile release deploys into: nvcf-backend, nvca-system, openbao-system and envoy-gateway-system are gone, and cert-manager and nvcf-ui are probed (b8faf70, TestControlPlaneNamespaceList_ExcludesRuntimeOwnedNamespaces). With a local stack the list is also derived from the helmfile.d namespace declarations, skipping templated values, and unioned with the static list as a floor (7aba33b, ce9f770, TestResolveStackNamespaces_UnionsStackWithStatic). A namespace with no Helm release, such as vault-system or cert-manager installed outside helmfile, is a warning whose hint inspects the namespace instead of deleting it; only a namespace stuck Terminating fails the run (bb0d56b, e5ab3dd, TestStaleNamespaceCheck_NoHelmReleaseWarnsAndDoesNotSuggestDelete). The other copies of the namespace set elsewhere in the CLI were not consolidated in this PR.

This test mutates whatever cluster is in the developer's current kubecontext.
Its two siblings — TestCheck_ComputePlaneFlagRunsChecks (L435) and TestCheck_ControlPlaneFlagRunsChecks (L467) — both set t.Setenv("NVCF_CLI_SELFHOSTED_SKIP_INOTIFY", "1"). This one sets neither that nor NVCF_CLI_SELFHOSTED_LOCAL_ONLY, and --skip-cluster-validation does not gate the inotify prober. So runPreflightByRole constructs the real NewInotifyProber, which lists every node and creates a privileged busybox:1.36 pod per node in default (inotify_probe.go:40,175).
go test ./cmd/ on an engineer's laptop or a CI runner that happens to have a kubeconfig will write to a live cluster.
Broader: neither of the two new test seams (newStaleNamespaceProberForSelfHosted, newRegistryCredentialCheckerForSelfHosted, self_hosted_check.go:64,72) is stubbed by any test, so all four new cmd tests load the real kubeconfig through the exec credential plugin and make live HTTPS calls — EnumerateRegistries always yields quay.io, so registryChecker is always constructed, at 10s+ per probe on a network-isolated box.
There was a problem hiding this comment.
That test now sets NVCF_CLI_SELFHOSTED_SKIP_INOTIFY like its siblings (ff14b5d). TestMain in cmd/main_test.go also stubs every seam that would reach a cluster or the network by default: the inotify prober, the stale-namespace prober, the registry credential checker and the validator tag lookup (e5ab3dd), plus the validator Job, with SIS pointed at a local test server (d642bef). Tests that exercise a path reassign the seam themselves, as runCheckRecording does for the stale-namespace prober.

ModeSingle still runs both role check sets unconditionally, so now that --control-plane / --compute-plane reach runPreflightByRole, each flag executes the other plane's probes too.
runOnce dispatches on checkPre || checkAll || checkControlPlane || checkComputePlane (L238), but L491-492 call RunPreflightForRole for both roles regardless of which flag was passed. check --control-plane therefore:
- resolves
icmsURL(L400:checkAll || checkComputePlane || !checkPreis true becausecheckPreis false) and fires an HTTP request atsis.nvcf.nvidia.com; - creates busybox probe pods on every node unless
--skip-inotify-checkis passed; - emits
gpu-operator/gpu-node-labelsrows.
None of which the operator asked for.
Separately, computePlaneIsTargeted is referenced only at L146 and L160 — never at the construction site. L417 gates clusterValidator only on clusterValidatorImage != "", unlike cpClusterValidator at L430 which correctly gates on controlPlaneIsTargeted(mode). Consequences: in ModeSplit, --control-plane creates a ServiceAccount, cluster-wide ClusterRole/CRB, pull secret and validator Job in the compute cluster; and in ModeSingle two 5-minute Jobs run sequentially under a 6-minute ceiling that L160 sizes only when both predicates are true — so the second vctx is truncated and reports a spurious context deadline exceeded plus a leaked running Job.
There was a problem hiding this comment.
ModeSingle now runs only the roles the flags select, so --control-plane sends no SIS request, creates no inotify probe pods and emits no GPU rows (ff14b5d, af2c3c3, TestCheck_SISReachabilityScope, TestCheck_StaleNamespacesFollowTheRequestedRoles). The compute-plane validator is gated on the compute plane being visited, the same way the control-plane one is (bb0d56b), and in ModeSplit --control-plane never contacts the compute cluster (46bac78, TestCheck_SplitModeControlPlaneOnlySkipsComputeCluster). Two sequential validator Jobs now run only when both roles are selected in ModeSingle, which is the case the 12 minute ceiling is sized for.

sweepPriorClusterValidatorJobs selects on labels that are identical for both roles, so in ModeSingle the compute-plane run deletes the control-plane run's Job inside the same command — including under --no-cleanup, which makes the printed kubectl logs job/... hint 404. Adding the role to clusterValidatorLabels() would fix both this and the shared-ConfigMap issue above.
There was a problem hiding this comment.
Every object a run creates now carries a role label and a random run ID, and the prior-Job sweep is gone: each Job has an active deadline and a TTL, so a role-wide sweep could only ever hit an overlapping run's live Job (ff14b5d, 6e32129, e5ab3dd). A ModeSingle run therefore cannot delete the other role's Job, and --no-cleanup keeps the Job so the printed kubectl logs hint resolves (3531290, TestRunClusterValidator_NoCleanupKeepsPullSecretAndPriorJob). The ConfigMap is covered in my reply on the ConfigMap thread.

staleNSProber is handed to both RoleConfigs (L464 and L480), so ModeSingle probes twice, emits two check_completed events with the identical ID stale-namespaces, and calls loadKubeConfig twice — two exec-credential-plugin invocations, i.e. a double MFA/tsh challenge per run. cluster-validator has the same duplicate-ID problem. The registry category was explicitly de-duplicated for exactly this reason (preflight.go:348-355); worth doing the same here.
Related, same file: maybeShowClusterValidatorLogs (L349) returns after the first match, so --all --show-logs silently drops one of the two transcripts.
There was a problem hiding this comment.
In ModeSingle the stale-namespace probe now goes to one role only, so there is one stale-namespaces event and one kubeconfig load (ff14b5d); when both roles run, the other role's namespaces are merged into that probe (13ddd00, af2c3c3). --show-logs no longer returns after the first match and prints both transcripts, pinned by TestMaybeShowClusterValidatorLogs_PrintsBothRoles (e5ab3dd). The two cluster-validator results keep one ID on purpose: they are separate Jobs running different check sets, and each is emitted under its own category (control-plane-cluster, compute-plane-cluster).

The security control added in the last commit has zero executable coverage.
TestExchangeBearerToken_DockerHubDelegatedRealm (L388) never calls exchangeBearerToken — it asserts the trustedRealmDelegations map literal against itself, so it passes if the realm check is deleted.
TestExchangeBearerToken_RejectsAttackerRealm (L344) builds a spyTransport and then discards it with _ = spy, and its guard can never fire because the realm check returns before any request is issued. The assertion that no credentials were forwarded is therefore vacuous.
To actually pin this: wire the spyTransport into the client passed to exchangeBearerToken, and assert both the returned error and that spy recorded zero requests carrying an Authorization header.
There was a problem hiding this comment.
Both tests now call exchangeBearerToken (ff14b5d). TestExchangeBearerToken_RejectsAttackerRealm passes a recording transport in the client and asserts the error, that no request carried an Authorization header, and that nothing reached the attacker host; it also configures Docker credentials for the registry (178461e), since NGC_API_KEY never applies to a non-NGC registry and left that assertion vacuous. TestExchangeBearerToken_DockerHubDelegatedRealm drives the auth.docker.io delegation and asserts the token request reached that host.

Three smaller things in this block:
- Source 3 always adds
quay.io, so the registry category (and a 10s probe) runs on every non-local invocation. The rationale is also inverted:global.yaml.gotmpl:78-103mirrors every cert-manager image toglobal.image.registryinstead ofquay.io/jetstack— so on a configured stack this probes a registry the install never contacts. - IPv6 extras lose their brackets:
[::1]:5000round-trips throughparseRegistryHostPort+fmt.Sprintf("%s:%d")into::1:5000, producinghttps://::1:5000/v2/. - Source 1 bypasses
add(L163-166 setsseenand appends directly), which is why it escapes theCriticalpolicy the closure would otherwise apply. Routing it throughaddwith aRepoHintparameter would remove that divergence.
There was a problem hiding this comment.
All three are addressed (b8faf70). quay.io is now probed only when the stack does not override the ACME solver image: global.yaml.gotmpl moves the cert-manager controller images to the mirror, but the solver keeps quay.io/jetstack unless certManager.acmesolver.image is set, so that is the one quay.io pull a mirrored install still makes (d642bef, TestEnumerateRegistries_QuayFollowsTheACMESolverImage). Extras with a port go through net.JoinHostPort, so [::1]:5000 stays bracketed (TestEnumerateRegistries_BracketsIPv6Extras). Source 1 goes through add with a repoHint parameter, so it gets the same host validation and criticality rule as every other source.

The allowlist fails open when u.Hostname() is empty: trustedRealmDelegations[regHost] returns "", which equals realmHost, so https://:443/token satisfies realmOK. The u.Host == "" guard at L202 does not catch it because Host is ":443", not empty.
It is blocked downstream today by the TLS handshake failing, so this is not exploitable as written — but it is a fail-open in a control that was added to fail closed. An explicit realmHost == "" rejection is one line.

…oc comments An earlier insertion landed isBareRegistryHost's doc inside isNGCRegistry's comment block, leaving one function undocumented and the other described by two stacked paragraphs. Same insertion-before-anchor pattern fixed elsewhere in this branch; no behaviour change.
The pull Secret and the network-checks ConfigMap were both created under predictable names and owned by labels alone. The managed labels are three public constants, so anyone able to create objects in the validator's namespace could pre-create either name wearing those labels, pass the ownership check, and receive whatever the run wrote there. For the Secret that is the NGC credential. Both names now carry the run's unguessable suffix, matching what the RBAC objects already did, and the Secret write is create-only: nothing this CLI created can hold a name it just generated, so an AlreadyExists means another object does and erroring beats overwriting. That removed the last caller of refuseIfUnmanaged, which is deleted here. Run-scoping also removes two lifetime conflicts. Two overlapping commands no longer share one ConfigMap, where the first to finish deleted config the other pod had not read yet; and a sweep can no longer delete a Secret another run selected. The orphan sweeper gains Secret and ConfigMap arms, because run-scoped names removed the accidental self-healing a fixed name gave us: a killed run used to leave one object the next run overwrote, and would now leave one per run, per --wait poll. Also here: the Job carries activeDeadlineSeconds, so an ImagePullBackOff can reach a terminal state and its TTL can fire rather than leaking the Job, its cluster-wide RBAC and its pull secret indefinitely; --no-cleanup marks every object it preserves so the orphan sweeper spares them instead of reclaiming a deliberately kept run after 30 minutes; and enforcement is disabled in the preflight template, since a readiness check should not create namespaces, pods and NetworkPolicies or need Docker Hub egress before anything is installed.

… other resources The RBAC objects, the pull Secret and the network-checks ConfigMap all take the preserve marker when --no-cleanup is set; the Job did not. The run that sets the flag already skips the prior-Job sweep, so this only showed up later: the next ordinary run of the same role deleted the Job an operator had kept, while its ConfigMap, RBAC and Secret survived, leaving those pointing at a Job that no longer existed. The Job now carries the marker and the sweep skips anything wearing it. The role selector is unaffected, since a label selector matches on subset.

There was a problem hiding this comment.
The cross-PR ordering blocker is still open, and the *IsVisited fix widened it: --pre in ModeSplit now also dispatches the control-plane validator.
resolveClusterValidatorImage (671-680) still auto-discovers the latest stable tag with no pin or minimum version. Until a #781-built tag is the highest stable tag, check --pre --control-plane-context cp --compute-plane-context gpu resolves a pre-#781 binary. That binary never reads VALIDATOR_ROLE, so it runs its critical GPU Resources check on the CPU-only control plane: the Job fails, the row is error severity, and the command exits 2. At 49ef18a, split --pre never ran the validator. .nvcf-cli.yaml.template:146-147 still says one image serves both roles.
The fix is small: add a minimum-version constant checked against the resolved tag. Below it, skip the control-plane validator and print a note.
There was a problem hiding this comment.
No minimum-version constant was added. When a control-plane transcript has no Validator role: line and does show the compute-plane GPU Resources section, the check now reports a warning that the image lacks role support instead of a failed control plane. Split --pre against a pre-#781 image therefore no longer fails the run (fbe7599, 178461e). A missing role line alone does not trigger this, so a role-aware image that fails early still fails; TestClusterValidatorCheck_PreRoleImageIsAWarning covers both cases, and the config template now describes the warning. #781 prints the role line, and the two PRs are planned to merge together.

Cross-role adoption is blocked now, but the adopt branch still returns other runs' same-role managed Secrets. Those Secrets are now per-run, so this reuses stale credentials and reintroduces the mid-pull delete.
- Stale key: run 1 with a bad
NGC_API_KEYgets ErrImagePull, so its Secret is kept (podMayBeRunning). The operator fixes the key and re-runs within 30 minutes. Run 2 adopts run 1's Secret beforeautoCreatePullSecretFromEnvruns, and hits the same 401 (reproduced). - Permanent adoption: a
--no-cleanupSecret (preserve label, never orphan-swept) is adopted by every later run forever, so a key rotation breaks the validator permanently. - Outlives the run: the adopted NGC-key Secret outlives a successful run, because clustervalidator.go:579 deletes only this run's name. The role-wide sweep at 49ef18a removed it.
- Mid-pull delete: with two overlapping same-role runs, A's sweep deletes the Secret B adopted, and B gets
FailedToRetrieveImagePullSecret.
Fix: skip every managed Secret here (hasValidatorManagedLabels → continue). Only adopt Secrets the operator created.
There was a problem hiding this comment.
The adopt branch now skips every Secret any version of this CLI minted: ones with our managed labels, ones with a released CLI's labels, and ones with the validator pull-secret name prefix. Only operator-created Secrets in default are adopted (6e32129, 178461e). That covers the stale-key, preserved-Secret and overlapping-run cases. TestScanAndMirrorPullSecret_NeverAdoptsAnotherRunsSecret and TestScanAndMirrorPullSecret_NeverAdoptsAReleasedCLIsSecret pin it.

activeDeadlineSeconds plus the TTL reclaim only the Job and its pod, so the comment above is not accurate. The per-run SA, ClusterRole/CRB, NGC pull Secret and ConfigMap have no ownerReferences, so on the pull-failure and timeout paths nothing reclaims them except a future run's orphan sweep, 30 or more minutes later.
When the validator image can't be pulled, waitErr is set, podMayBeRunning=true, and all three defers are skipped. The Job hits DeadlineExceeded at 360s and is TTL-deleted 600s later. What stays behind: the ClusterRole (cluster-wide create/delete on pods, namespaces, daemonsets and services), its SA and binding, a Secret holding $oauthtoken:$NGC_API_KEY, and the ConfigMap. They remain until a later check starts at least 30 minutes afterwards (the orphan sweep runs only at :153), and forever if none does. Under --wait, with another error row failing, every poll adds another set.
Fix: set ownerReferences from the SA, Secret and ConfigMap to the Job, so the TTL cascades. On the pull-failure path, where the container never started, delete the Job and run the sweeps.
There was a problem hiding this comment.
The Job now owns this run's pull Secret and ConfigMap, so its deadline and TTL remove them on the timeout path (6e32129). On a pull failure, and on an interrupt, the Job is deleted and every deferred sweep runs immediately (6e32129, 178461e); TestRunClusterValidator_PullFailureLeavesNothingBehind, _InterruptLeavesNothingBehind and _RunningPodKeepsRBACAndJobOwnsArtifacts pin this. The ServiceAccount, ClusterRole and binding are deliberately not owned: the cluster-scoped objects cannot have a namespaced owner, and removing the account alone would leave a binding that anyone recreating that name could inherit. So after a plain timeout they still wait for a later check's orphan sweep, 30 minutes or more later.

The --no-cleanup fix over-corrects, and this help text is now wrong. Everything a --no-cleanup run creates is exempt from every reclaim path, yet this text and flags.md:55 still say the next run sweeps prior Jobs.
One check --no-cleanup leaves behind:
- a Job with no TTL;
- the SA/ClusterRole/CRB;
- the NGC-key Secret;
- the ConfigMap.
All of it is labelled validator-preserve=true. The prior-Job sweep (clustervalidator.go:551) and the orphan sweep (422/434/445) skip these objects, down/uninstall never touch them, and no cleanup command is printed. The result is a permanent privileged SA in default that anyone able to create pods there can use, plus a permanent NGC key. --wait --no-cleanup mints a full preserved set per poll. Separately, activeDeadlineSeconds is set unconditionally, so it also deletes the preserved pod 60s after a CLI timeout.
Suggest: give preserved objects a long TTL (e.g. 24h) in the orphan sweep rather than exempting them, and print the exact kubectl delete line when --no-cleanup is used.
There was a problem hiding this comment.
Preserved objects are no longer exempt: the orphan sweep reclaims them after 24 hours, including the preserved Job. A --no-cleanup result prints the exact kubectl delete for that run's label, also when the RBAC bootstrap fails (6e32129, 8581a78). A preserved Job no longer gets activeDeadlineSeconds, so the kept pod and its logs survive, and the help text and flags.md say all this. down and uninstall still do not touch these objects.

There was a problem hiding this comment.
enabled: false does not stop the preflight from mutating the cluster or pulling from Docker Hub. #781 uses enforcement.testImage for its critical node-to-node probe under the control-plane role, whatever enabled says, and the CLI has no way to override it.
Take check --pre on a multi-node air-gapped or mirror-only control plane. #781 (validator.go:193-202, checks.go:1268-1273) creates an nvcf-n2n-validation-* namespace, a busybox:1.36 DaemonSet on every node, and a checker pod. The pulls fail, the critical Node-to-Node row fails, the validator exits non-zero, and the CLI exits 2. So fe418dd's stated goal, a read-only check with no Docker Hub egress, is not met.
Either expose the image as a flag (defaulting to the stack's global.image.registry mirror), or have the preflight role skip the active overlay probe entirely.
There was a problem hiding this comment.
The overlay probe image can now be set with --cluster-validator-probe-image, NVCF_CLI_CLUSTER_VALIDATOR_PROBE_IMAGE or the config file. It is forwarded as NVCF_N2N_PROBE_IMAGE, which #781 prefers over enforcement.testImage (d642bef, documented in 8807222). The default is still busybox:1.36 from Docker Hub rather than the stack mirror, and the probe still creates its namespace, DaemonSet and checker pod, so an air-gapped --pre needs the flag set. TestClusterValidatorJobEnv covers the forwarding.

Still unanswered from last round: the SIS gate makes --pre veto sis-reachability even under --all, which contradicts --all being documented as "Run all check categories". If that's intended, a one-line note in flags.md would settle it.
Related doc drift: help :110-111 and flags.md:53 still promise NGC_API_KEY minting for any registry, but minting is now isNGCRegistry-gated (pullsecret.go:251). The mirror path (104-116, 183-224) also still copies Secrets out of vault-system/api-keys/nvcf into default without telling the operator.
There was a problem hiding this comment.
Only a bare --pre skips SIS now. --pre --all and --pre --compute-plane probe it, --control-plane never does, and flags.md says so for --pre and --all (af2c3c3, TestCheck_SISReachabilityScope). The help text and flags.md now say NGC_API_KEY minting happens only for an image on an NGC registry. They also say a matching Secret found in an NVCF namespace is copied into default for the run (6e32129). The run itself still prints no notice when it copies one. The copy uses a per-run name and is removed with the run's other artifacts.

This regression guard only passes because of test order. Its cleanup never resets checkPre, and neither do several earlier tests that pass --pre (TestCheck_NewJSON at :67, also :78/:175/:270/:301). computePlaneIsVisited() is checkComputePlane || checkAll || checkPre, so when checkPre=true leaks in, a --control-plane-only split run dispatches the compute cluster, which is exactly what this test is meant to catch.
Deterministic repro at this head: go test -count=1 -run 'TestCheck_NewJSON$|TestCheck_SplitModeControlPlaneOnlySkipsComputeCluster$' ./cmd/ fails with [compute-plane-cluster local-host-tools registry-credentials control-plane-cluster] should not contain "compute-plane-cluster". It also fails under -shuffle with seeds 1, 2, 3, 4 and 6. In file order it passes only because the two tests that run just before it happen to reset checkPre.
The --pre tests also leak selfHostedWait="2s", and TestCheck_ControlPlaneFlagRunsChecks / TestCheck_ComputePlaneFlagRunsChecks silently run with --pre active. A shared resetCheckFlags(t) helper, registered via t.Cleanup in every test that calls rootCmd.Execute, would fix this for good.
There was a problem hiding this comment.
resetCheckFlags now resets every check flag to its default, before and after each test. That covers checkPre, selfHostedWait, the output mode, the context flags, cobra's Changed markers and the viper bindings. Every test that runs check calls it (d642bef). Your repro passes at this head, as do -shuffle seeds 1, 2, 3, 4 and 6, and -shuffle=on across all TestCheck_ tests.

This hardcoded nvcr.io endpoint is critical: true and can't be removed, so the control-plane validator hard-fails on every mirrored, air-gapped or proxy-only control plane.
#781 has no built-in nvcr.io probe, so this template is the only source of it, and #781's testTCP is a raw dial with no proxy support (connectivity.go:86-87). Take a cluster where global.image.registry and cluster_validator_image point at an internal Harbor and there is no direct egress. check --pre (ModeSingle, and now ModeSplit), --control-plane or --all dials nvcr.io:443 and fails. That fails the critical reachability row (#781 validator.go:289-296), and the CLI exits 2 with cluster-validator reported failures. --cluster-validator-registries can only add endpoints. The only way out is --skip-cluster-validation, which drops every validator check.
This contradicts the CLI's own policy in registry_cred.go:327-330, which deliberately skips nvcr.io for exactly this install shape ("a mirrored install, which has no reason to reach nvcr.io"). Build the reachability list from the same EnumerateRegistries result so both paths agree. The flag help at self_hosted_check.go:119 ("nvcr.io is always included") needs the same change.
There was a problem hiding this comment.
The hardcoded nvcr.io entry is gone. The ConfigMap endpoints are now the same EnumerateRegistries result the local credential check uses, with the same criticality, so a mirrored install is never made to dial nvcr.io (d642bef). TestBuildControlPlaneValidatorConfig_NoRegistries and TestBuildControlPlaneValidatorConfig_FollowsEnumeratedRegistries pin it. The --cluster-validator-registries help (d642bef) and flags.md (8807222) now describe that registry set instead of saying nvcr.io is always included.

No test pins the cleanup wiring this delta was written to fix.
I checked this by mutating a scratch copy and running go test ./internal/selfhosted/:
- Deleting all three deferred sweeps (pull secret :171, RBAC here, ConfigMap :204) and moving
sweepOrphanClusterValidatorRBACfrom :153 to after pull-secret resolution leaves the suite green. - Reverting
sweepManagedPullSecrets' exact-name check to the 49ef18a prefix match, which deletes a concurrent same-role run's Secret, also leaves it green.
The closest tests don't assert the outcome:
TestRunClusterValidator_RBACNameCollisionIsNotAdoptedmakes bootstrap fail after the SA exists, but never checks that the SA was removed.TestRunClusterValidator_HappyPathnever checks that the SA, ClusterRole, CRB, Secret or ConfigMap are gone.TestManagedPullSecret_IsScopedPerRoleseeds no second same-role run.
So last round's SA-leak fix, the ConfigMap-leak fix and the sweep ordering could all regress without a test failing. Asserting "nothing with this runID remains" after the happy path and after each failure path would cover all of them.
There was a problem hiding this comment.
Lifecycle tests now check, by run label, that a run leaves no ServiceAccount, ClusterRole, ClusterRoleBinding, Secret or ConfigMap behind. They cover the happy path, a bootstrap that fails after the ServiceAccount exists, and a pull failure (6e32129), plus an interrupt (178461e). TestRunClusterValidator_SparesConcurrentSameRoleSecret seeds a second same-role run's Secret, so going back to a prefix match fails it. The orphan-sweep ordering has no test of its own. That sweep only deletes objects older than 30 minutes, so it cannot reach a Secret this run just created.

When CLI versions are mixed on one cluster, each deletes the other's in-flight validator objects.
clusterValidatorLabels() (:338, unchanged from main) still stamps app.kubernetes.io/name=nvcf-cluster-validator,app.kubernetes.io/managed-by=nvcf-cli on the new per-run objects and on --no-cleanup preserved objects. That is exactly the selector the released CLI (main c8c73ff, shipped with the self-managed v0.10.0+ stacks) passes to DeleteCollection.
- Released CLI deletes this PR's objects: every released-CLI run starts by
DeleteCollection-ing all Jobs matching that selector (main clustervalidator.go:243-245), and on exit all matching Secrets (:261-262). That removes this PR's in-flight Jobs for both roles, its per-run pull Secret mid-pull (FailedToRetrieveImagePullSecret), and every--no-cleanuppreserved Job and Secret. This PR's claims that a sweep can no longer take out another run's Secret, and that preserved artifacts survive later runs, don't hold while the released CLI is in use. - This PR deletes the released CLI's objects: the released CLI keeps a fixed-name
nvcf-preflight-validatorSA/ClusterRole/CRB permanently and refreshes the ClusterRole with Get+Update, so itscreationTimestampis from the first-ever run. Thisreclaimablecheck matches that prefix, those labels and that age, and deletes them. A released-CLI validator pod running at that moment gets 403s.
Operators will run both versions against the same cluster during any rollout. Giving the new objects a distinct managed-by value (or name), and excluding the exact legacy name from the orphan sweep, would stop them interfering.
There was a problem hiding this comment.
New objects are now labelled managed-by=nvcf-cli-validator, so a released CLI's DeleteCollection on managed-by=nvcf-cli no longer matches them, and this CLI's selector no longer matches the released objects (6e32129). The orphan sweep also requires the per-run nvcf-preflight-validator- prefix, which excludes the fixed legacy name. TestSweepOrphanClusterValidatorRBAC_PreservedExpireAndLegacyIsSpared pins it. The pull-secret scan also never adopts a released CLI's Secret (178461e, TestScanAndMirrorPullSecret_NeverAdoptsAReleasedCLIsSecret).

nvcf self-hosted check: a control-plane clustervalidator (wired to the companion nvca PR #781), stale-namespace detection
before install, and pre-install registry credential validation over the generic
OCI Bearer token flow.
--compute-planewas previously a no-op and now works.Review of the first implementation found that everything the validator creates
in the cluster was named predictably and owned by labels alone, so the resource
lifecycle was reworked to per-run, unguessable names.
Behaviour changes for existing CI users
failure, timeout) now fails
checkwith exit code2. It used to be awarning and exit
0, so a CI gate passed without validating the cluster.Pass
--skip-cluster-validationto opt out explicitly.check(Ctrl-C, SIGTERM) now exits130and cleans up thevalidator's in-cluster objects before returning. A second Ctrl-C exits at once.
[!]instead of the failure mark.cluster_validator_imageconfigured, the validator isskipped with a stderr note and
checkdoes not fail.Additional Details
Role gating
Two predicate pairs drive the run.
*IsTargeteddecides whether a role's owncheck set runs;
*IsVisiteddecides whether a cluster is contacted at all.--prein ModeSplit visits both clusters for the shared pre-install checkswithout targeting either role, so the dispatch, image resolution, the inotify
probe and the skip note all key off
*IsVisited. Gating them on*IsTargetedmade
--prein split mode silently run neither validator nor the inotify probe,and print no note explaining why.
*IsVisitedtakes no mode argument:(X || (pre && single)) || preabsorbs toX || pre, so the mode cannot change the answer.Run-scoped resource names
The pull Secret and the network-checks ConfigMap were created under predictable
names and owned by labels alone. The managed labels are three public constants,
so anyone able to create objects in the validator's namespace could pre-create
either name wearing them, pass the ownership check, and receive whatever the run
wrote there. For the Secret that is the NGC credential.
Both names now carry the run's unguessable suffix, matching what the RBAC
objects already did, and the Secret write is create-only: nothing this CLI
created can already hold a name it just generated, so
AlreadyExistsmeansanother object does and erroring beats overwriting.
Run-scoping also removes two lifetime conflicts. Two overlapping commands no
longer share one ConfigMap, where the first to finish deleted config the other
pod had not read yet; and one run's sweep can no longer delete a Secret another
run selected. It cost the accidental self-healing a fixed name gave us, so the
orphan sweeper gained Secret and ConfigMap arms.
Resource lifecycle
activeDeadlineSecondson the Job, so anImagePullBackOffreaches aterminal state and its TTL fires. Without it the Job, its cluster-wide
ClusterRole and its pull secret leaked indefinitely on the exact failure mode
operators retry.
--no-cleanupmarks every object it preserves, so the orphan sweeper sparesthem rather than reclaiming a deliberately kept run after 30 minutes.
that can create a ServiceAccount but not a cluster-scoped ClusterRole no
longer abandons one per attempt (roughly 360 under
--wait 30m).for the same image, so it is not rejected under PodSecurity
restrictedandschedules on a cluster whose nodes all carry the control-plane taint.
VALIDATOR_PREFLIGHTonlysuppresses the summary write, so a readiness check was creating namespaces,
pods and NetworkPolicies and pulling busybox from Docker Hub before anything
was installed.
Credential handling
NGC_API_KEYis only minted for NGC registries. An operator mirroring thevalidator image to
ghcr.ioor a corporate Harbor would otherwise have thekubelet send the live key there as HTTP Basic auth.
Every registry string passes the same host validation, so a values file setting
global.image.registryto a host-moving value cannot aim an outbound request.--envreplacesHELMFILE_ENVwhen resolving the stack values file:HELMFILE_ENVis only injected into the helmfile subprocess, so reading it inthis process always fell through to
base.yamland credential-checked aregistry the install would never pull from.
Stale namespace detection
Two conditions are reported. A namespace stuck Terminating fails the run. "No
Helm release" now warns instead, and is suppressed entirely unless at least one
owner=helmobject was seen somewhere, becauseHELM_DRIVER=sqlkeeps releasestate in a database with no in-cluster object at all.
The remediation inspects rather than deletes. The stack gates cert-manager,
NATS, OpenBao and Cassandra on
*.enabled, so an operator who installs one thedocumented upstream way owns a healthy namespace with no
owner=helmobject;the previous
kubectl delete namespace cert-managerwould have destroyed everyCertificate and Issuer in the cluster.
JSON contract
successand the exit code now derive from one predicate. A warning-severityresult previously emitted
success:falseandverdict:failedwhile the processexited 0, so a CI gate on
final.successbroke for every user whose registrycredentials live in a Docker credential helper. The already-documented
warningsverdict is now emitted.For the Reviewer
cmd/self_hosted_check.go: the*IsVisitedpredicates and everything gated onthem,
isBlockingFailureas the single failure definition,resolveStackValuesFile.internal/selfhosted/clustervalidator.go: run-scoped names, the orphan sweeperarms,
activeDeadlineSeconds, the preserve label, the Job pod shape.internal/selfhosted/pullsecret.go: create-onlywriteDockerConfigSecret, theNGC-registry gate, role-scoped adoption.
internal/selfhosted/stale_namespace.go: theanyHelmReleaseSeengate.internal/selfhosted/registry_cred.go: host validation on every source, theIPv6 bracket guard.
cmd/main_test.go: the seams that make the package hermetic.Worth reading the commit body on
fe418ddf0: the security rationale forcreate-only writes and run-scoped names is the part that cannot be inferred from
the diff.
For QA
go build,go vetand the full module suite pass; all 21 bazel targets pass.The
cmdpackage is now hermetic. It previously created a hostPath busybox podper node in
default, listed Secrets across the stack namespaces of whateverkubeconfig happened to be current, and made an outbound request per configured
registry.
TestMainstubs the inotify, stale-namespace and registry seams, andthe package went from about 49s, or minutes against a proxied kubeconfig, to 19s.
Behavioural guards are mutation-tested: each was verified by breaking it and
confirming a test fails. That caught two guards passing for the wrong reason,
including one that was unreachable because the ConfigMap never carried the label
it checked.
Verified on k3d
ncp-localwith the NVCF stack deployed:NGC_API_KEYconfirmed not sent to non-NGC registries.VALIDATOR_ROLE=control-planeconfirmed in the Job env.No further QA needed.
Merge order: this depends on #781.
VALIDATOR_ROLEis set on the Job here butnothing reads it until #781 lands, so
check --control-planeexits 2 on ahealthy control plane until then. #781 must merge first.
Deferred, with reasons on the review threads: gating the quay.io probe on
certManager.acmesolver.image.repositoryrather than on values-file resolution;Docker credential-helper (
credsStore,credHelpers) support; and making thevalidator namespace configurable rather than the
defaultconstant.Issues
