### Second-order CRDs need a THIRD pass (`platform-config-cdi`, added 2026-09-05)
|
||||||
|
|
||||||
|
The controllers/configs split (`platform` → `platform-config`) assumes a CRD is registered by the
|
||||||
|
controller **install**. CDI breaks that: `cdi-operator.yaml` registers only `cdis.cdi.kubevirt.io`,
|
||||||
|
and cdi-operator creates `storageprofiles` / `datavolumes` / `datasources` **only after it has
|
||||||
|
reconciled the `CDI` CR**. Since kustomize-controller server-side **dry-runs every object in a pass
|
||||||
|
before applying any of them**, having the `CDI` CR and the CDI `StorageProfile`s in one pass was a
|
||||||
|
**deadlock, not a race**: unknown kind → pass aborts → CR never applied → CRD never created →
|
||||||
|
`platform-config` can never converge → every tier below it blocked. Invisible on dev (its CDI CRDs
|
||||||
|
have existed for months); it cost 12h on prod's cold start.
|
||||||
|
|
||||||
|
So there is a third tier, `platform-config-cdi` (`./platform-config-cdi`, `dependsOn:
|
||||||
|
platform-config`), and a rule:
|
||||||
|
|
||||||
|
> A CR belongs in `platform-config-cdi`, not `platform-config`, when the CRD it needs is created by a
|
||||||
|
> **controller at runtime** rather than by a manifest in git.
|
||||||
|
|
||||||
|
`apps-vms` `dependsOn` it as well as `platform-config`, because CDI reads
|
||||||
|
`StorageProfile/longhorn-vm` at DataVolume **provisioning** time — a VM disk provisioned before that
|
||||||
|
profile exists is stamped RWO/Filesystem and is permanently not live-migratable.

|

|

|

|
# `bootstrap/standup.sh crds` pre-applies the `CDI` CR to break it by hand. That is a WORKAROUND and

# stays as belt-and-braces for clusters already wedged; THIS Kustomization is the fix that makes the
|
||||||
|
# graph order itself, so a cold cluster needs no human in the loop.
|

|
#
|
||||||
|
# THE ORDERING GUARANTEE, precisely: `dependsOn` is REVISION-gated, not merely Ready-gated (verified
|
||||||
|
# against kustomize-controller v1.4.0 `kustomization_controller.go :: checkDependencies`, our
|
||||||
|
# version): sharing a GitRepository with the dependency, this Kustomization cannot reconcile revision
|

|
# N until `platform-config` has APPLIED revision N — and, because platform-config runs `wait: true`,
|
||||||
|
# not until the `CDI` CR it applied is HEALTHY. cdi-operator creates the remaining CDI CRDs as part of
|
||||||
|
# reaching that state, so by the time this tier's first dry-run runs, `StorageProfile` is a known
|
||||||
|
# kind. One edge, no pre-apply.
|
||||||
|
#
|
||||||
|
# WHY NOT just move the CDI CR earlier, into `platform`? Because `platform` is the tier the CNI gates
|
||||||
|
# and everything else waits on: putting CDI's health on that critical path is the mistake the
|
||||||
|
# oauth2-proxy/headlamp splits were made to undo. The CR is correctly a platform-config CR; it is the
|
||||||
|
# StorageProfiles that were in the wrong pass.

|
# nothing else in the repo declares a StorageProfile. The stale set is exactly two
|
||||||
|
# cluster-scoped CDI CRs.
|
||||||
|
# * The objects do not actually go missing: CDI's storageprofile-controller creates a
|
||||||
|
# StorageProfile per StorageClass and recreates a deleted one, with an EMPTY `.spec` and
|
||||||
|
# inferred `.status`. So the transient is "our .spec overrides are absent", not "the object is
|
||||||
|
# absent".
|
||||||
|
# * A StorageProfile is read at DataVolume/PVC PROVISIONING and CLONE time only. Existing PVCs,
|
||||||
|
# existing DataVolumes and running VMs do not consult it again, so nothing already provisioned
|
||||||
|
# is disturbed and no data path is touched.
|
||||||
|
# * The only exposure is a DataVolume/clone STARTED inside the window: it would clone by `copy`
|
||||||
|
# instead of `snapshot`, and on `longhorn-vm` be stamped RWO/Filesystem instead of RWX/Block —
|
||||||
|
# permanently non-live-migratable for that disk. Flux cannot cause that, because `apps-vms` now

# platform-config-cdi — the SECOND-ORDER config wave: custom resources whose CRD is created at
|
||||||
|
# RUNTIME by a controller that a `platform-config` custom resource switches on.
|
||||||
|
#
|
||||||
|
# ── THE BUG THIS DIRECTORY EXISTS TO FIX (observed on PROD, 2026-09-05) ───────────────────────────
|
||||||
|
# The repo already splits CONTROLLERS (`platform`) from CONFIGS (`platform-config`) because a CR
|
||||||
|
# cannot be dry-run before its CRD is registered. That split assumes a CRD is registered by the
|
||||||
|
# controller INSTALL. CDI breaks the assumption: `cdi-operator.yaml` registers exactly ONE CRD
|
||||||
|
# (`cdis.cdi.kubevirt.io`). Every OTHER CDI CRD — `storageprofiles`, `datavolumes`, `datasources`,
|
||||||
|
# `dataimportcrons`, … — is created by cdi-operator only AFTER it has reconciled the `CDI` CR.
|
||||||
|
#
|
||||||
|
# So `cdi-cr.yaml` is a FIRST-order CR (its CRD comes from the install) and belongs in
|
||||||
|
# platform-config, while `cdi-storageprofiles.yaml` is a SECOND-order CR (its CRD comes from
|
||||||
|
# reconciling the first-order CR). Having both in ONE Flux Kustomization is a true DEADLOCK, not a
|
||||||
|
# race: kustomize-controller server-side dry-runs EVERY object before applying ANY of them, so the
|
||||||
|
# unknown `StorageProfile` kind aborts the whole pass → the `CDI` CR is never applied → the
|
||||||
|
# StorageProfile CRD is never created → platform-config can NEVER converge, and every tier that
|
||||||
|
# dependsOn it stays blocked forever. On prod, cdi-operator sat Available for 12h with no CR:
|
||||||
|
#
|
||||||
|
# StorageProfile/longhorn dry-run failed: no matches for kind "StorageProfile"
|
||||||
|
# in version "cdi.kubevirt.io/v1beta1"
|

|
#
|
||||||
|
# Invisible on dev (whose CDI CRDs have existed for months) and fatal on any COLD cluster.

||||||

||||||

# ── THE RULE, so this is not rediscovered a third time ────────────────────────────────────────────

|
# A CR belongs HERE (not in platform-config) when the CRD it needs is created by a CONTROLLER AT

## Controller-generated pods (who sets the labels when git cannot)
|
||||||
|
|
||||||
|
`egress-class` / `auth-mode` are normally projected onto pod templates by the renderer (below).
|
||||||
|
Some pods are generated by a **controller at runtime** and therefore have no manifest in git to
|
||||||
|
label — CDI's `importer-*` / `uploader-*` / `cloner-*` worker pods are the live example: both
|
||||||
|
label policies denied CDI's importer on prod (2026-09-06) and the UniFi VM got no disk. For those,
|
||||||
|
`policies/label-cdi-worker-pods.yaml` **adds** the labels at admission (`+(…)` add-if-absent),
|
||||||
|
matched on the **generating ServiceAccount** (`cdi/cdi-sa`) — never on a pod-name prefix or on
|
||||||
|
CDI's own labels, both of which any pod author in the namespace can copy. `virt-launcher-*` needs
|
||||||
|
nothing: KubeVirt propagates the VM pod-template labels onto it (verified on dev).

|

|
# `DataVolume unifi/unifi-rootdisk` sat in ImportScheduled for hours holding a detached
|
||||||
|
# 40Gi `prime-…` scratch PVC. `kubectl -n cdi logs deploy/cdi-deployment` showed:
|
||||||
|
# admission webhook "validate.kyverno.svc-fail" denied the request: resource
|
||||||
|
# Pod/unifi/importer-prime-<uid> was blocked due to the following policies
|
||||||
|
# require-auth-mode-label / require-egress-class-label
|
||||||
|
# CDI generates its own short-lived worker pods (importer-*, uploader-*, cloner-*/
|
||||||
|
# clone-source-*) from inside the cdi-deployment controller. Those pods are not in git,
|
||||||
|
# so nothing can put the platform labels on them, and both label policies match ANY Pod
|
||||||
|
# in a namespace labelled homelab.keithjackson.dev/app-namespace=true. Result: the VM
|
||||||
|
# never gets a disk. This is a COLD-START defect, not a prod quirk — dev's identical
|
||||||
|
# import Succeeded before the policies were enforcing, so dev has never exercised it and
|
||||||
|
# would hit it on any rebuild.
|
||||||
|
#
|
||||||
|
# WHY MUTATE (and not an exception/exclusion):
|
||||||
|
# The honest reading of R-NET-05/R-IDP-02 is "every pod's egress path and auth posture is
|
||||||
|
# DECLARED". A CDI importer pod has truthful values for both:
|
||||||
|
# egress-class: internet — it pulls the image from the public internet over https
|
||||||
|
# (cloud-images.ubuntu.com / quay.io) and must take the
|
||||||
|
# default WAN path, which is exactly what Cilium's egress
|
||||||
|
# gateway does for `internet` (ADR-0013/ADR-0015). It is NOT
|
||||||
|
# a `vpn` workload.
|
||||||
|
# auth-mode: none — the pod serves no UI and terminates when the import ends;
|
||||||
|
# there is nothing to put an IdP in front of. docs/13 permits
|
||||||
|
# `none` for internal, non-public workloads (the
|
||||||
|
# ServiceDefinition policy forbids only public + none).
|
||||||
|
# So the requirement is SATISFIED rather than bypassed: the invariant "every pod in an app
|
||||||
|
# namespace carries both labels" stays literally true cluster-wide, both label policies
|
||||||
|
# stay untouched (no `exclude`, no PolicyException, background scanning still on), and the
|
||||||
|
# labels are functional — the pod is now selectable by the Cilium egress fabric instead of
|
||||||
|
# being an unlabelled pod that silently falls through to the default path.
|
||||||
|
#
|
||||||
|
# THE MATCH IS THE GENERATING ServiceAccount, NOT A NAME PREFIX:
|
||||||
|
# `subjects: ServiceAccount cdi/cdi-sa` is the identity in the AdmissionReview's userInfo —
|
||||||
|
# the controller that issued the CREATE. Verified on prod from the Kyverno admission log of
|
||||||
|
# the blocked request:
|
||||||
|
# user={"username":"system:serviceaccount:cdi:cdi-sa", ...} roles=["cdi:cdi-deployment"]
|
||||||
|
# name=importer-prime-be3f9d1c-… namespace=unifi operation=CREATE
|
||||||
|
# A pod NAME (`importer-*`) or CDI's own labels (`cdi.kubevirt.io`) are attacker-CHOOSABLE:
|
||||||
|
# anyone who can create a pod in the namespace can name it `importer-prime-x` and copy the
|
||||||
|
# labels, and would then inherit the exemption. The requesting ServiceAccount cannot be
|
||||||
|
# chosen by the pod author — only by someone who already holds cdi-sa's token, which already
|
||||||
|
# confers "create any pod in any namespace" cluster-wide. So this adds no reachable
|
||||||
|
# privilege. It is also VERSION-ROBUST: it covers every CDI worker kind (importer, uploader,
|
||||||
|
# cloner/clone-source) without enumerating names that change between CDI releases —
|
||||||
|
# confirmed on prod that cdi-sa is the ONLY cdi-namespace ServiceAccount that can create
|
||||||
|
# pods (`kubectl auth can-i create pods -n unifi --as …`: cdi-sa yes; cdi-apiserver no;
|
||||||
|
# cdi-uploadproxy no).
|
||||||
|
#
|
||||||
|
# DELIBERATELY NOT COVERED — KubeVirt's own generated pods:
|
||||||
|
# virt-launcher-* pods INHERIT the VM's pod-template labels, so a VM authored in this repo
|
||||||
|
# already passes (verified on dev: virt-launcher-unifi-22dg7 carries egress-class=internet,
|
||||||
|
# auth-mode=native from apps/vms/unifi/30-virtualmachine.yaml). Exempting
|
||||||
|
# kubevirt-controller would REMOVE that useful enforcement on VM authors, so it is not done.
|
||||||
|
# KubeVirt's hotplug (`hp-volume-*`) and export (`virt-export-*`) pods do NOT inherit those
|
||||||
|
# labels, but nothing in this repo uses volume hotplug or VirtualMachineExport; if either is
|
||||||
|
# adopted, extend this policy then — with the same ServiceAccount-scoped shape.
|
||||||
|
#
|
||||||
|
# OPERATOR NOTE — this is the cluster's FIRST resource-MUTATING policy. Verified on prod
|
||||||
|
# 2026-09-06 that `kyverno-resource-mutating-webhook-cfg` currently holds 0 webhooks; with the
|
||||||
|
# chart's `autoUpdateWebhooks=true` Kyverno registers `mutate.kyverno.svc-fail` for Pods within
|
||||||
|
# seconds of this policy being applied. Prod runs `forceFailurePolicyIgnore=false`, so that
|
||||||
|
# webhook is failurePolicy: Fail — the same posture as the validating webhook that is ALREADY in
|
||||||
|
# the path for these pods, so no new fail-open surface and no new blocking surface. CDI retries
|
||||||
|
# the importer pod on a loop, so the stuck import proceeds once the policy lands (the detached
|
||||||
|
# `prime-…` scratch PVC left behind by the blocked attempts is a separate operator cleanup).
|
||||||
|
#
|
||||||
|
# RESIDUAL TRADE-OFF (state it plainly, it is reversible by deleting this file):
|
||||||
|
# Anything created by `cdi:cdi-sa` in an app namespace now gets `egress-class: internet` +
|
||||||
|
# `auth-mode: none` supplied for it instead of being rejected for not declaring them. Whoever
|
||||||
|
# holds cdi-sa's token can therefore run a pod in an app namespace without declaring its egress
|
||||||
|
# class. That identity can already create arbitrary pods in every namespace (ClusterRole `cdi`:
|
||||||
|
# pods create/delete cluster-wide), so it is not a new capability — but the declaration is now
|
||||||
|
# assumed rather than demanded for that one identity. Nothing else changes: the pod is still
|
||||||
|
# subject to restrict-host-namespaces, the namespace default-deny baseline, and every other
|
||||||
|
# policy, and `internet` is the LEAST-reach of the two egress classes (it does not grant the VPN
|
||||||
|
# path).
|
||||||
|
#
|
||||||
|
# PROOF (offline, no cluster — platform/kyverno/tests/controller-worker-pods/):
|
||||||
|
# (a) a CDI importer pod created by cdi:cdi-sa is mutated and then PASSES both policies;
|
||||||
|
# (b) the SAME namespace's ordinary pod — including one that FORGES the importer name and

||||||
|
# CDI's labels — is NOT mutated and is still DENIED by both policies.
