feat(bootstrap): automate the Kyverno CRD pre-apply — the last cold-start blocker
`platform/kyverno/admission/helmrelease.yaml` sets `crds: {install: false}`
because the CRD bundle is 5,636,155 bytes, far past kubectl's 256 KiB
last-applied-configuration limit — a client-side apply fails with
"metadata.annotations: Too long" and STALLS the HelmRelease.
The consequence nobody automated: with CRD install off, NOTHING installed
them. `platform` has `wait: true` and every other tier chains transitively
through it, so on a cold cluster Kyverno's API types never exist, `platform`
never goes Ready, and all 10 downstream tiers stall. Dev only ever had these
CRDs because they were applied BY HAND — exactly the undocumented manual step
this repo exists to eliminate.
New `bootstrap/flux/preapply-crds.sh`, wired into bootstrap.sh as step [2/4]
(after `flux install`, before the graph is applied) and standalone-safe so an
already-bootstrapped cluster can be unblocked without re-running bootstrap.
NO SECOND PIN: all four chart coordinates are read with yq out of the same
HelmRelease/HelmRepository pair Flux reconciles. The version is passed through
as the CONSTRAINT ("3.9.x"), not a resolved tag — helm and helm-controller both
use Masterminds/semver, so the render is the version Flux installs. Renovate
bumps one line and this step follows; there is nothing here to drift from.
Only `kind: CustomResourceDefinition` documents are applied. The by-hand
command recorded in the HelmRelease comment piped the WHOLE template into
kubectl, which would create Deployments/webhooks outside Helm's ownership and
then fight the HelmRelease over field managers.
THREE GUARDS, because a silent skip here reproduces a failure mode this repo
has been bitten by repeatedly:
1. any derived coordinate that is empty/null/multi-valued aborts;
2. rendered CRD count must be > 0 — this caught a real bug in the first
draft: on an empty render `yq .metadata.name` emits one BLANK line, which
counted as 1 CRD and sailed past the guard into an apply of an empty file
returning 0, i.e. the exact silent-success trap. Blank/null lines are now
dropped and a chart with no CRDs exits 1;
3. every applied CRD is waited on for condition=Established, so "kubectl
returned 0" is not the only evidence.
No opt-out flag, deliberately: a skipped CRD apply yields a cluster that looks
bootstrapped and reconciles nothing.
`roles/flux_bootstrap` is untouched — it already shells to bootstrap.sh, the
documented single entrypoint, so it inherits the step with no dev/prod fork
(R-ENV-02). A second role task would double-apply.
MEASURED, not assumed — reproduced under the PINNED toolchain (helm 3.16.0,
yq 4.44.6) in infra/devcontainer, matching an independent run on helm 3.20.0
byte-for-byte: 3.9.x resolves to 3.9.0, 22 CRDs, 5,636,155 bytes CRD-only
(5,870,019 full render). Largest single CRD document is 1,378,544 bytes —
under etcd's 1.5 MiB default, but not by much; worth watching on chart bumps.
NOT YET EXERCISED against a live API server: the server-side apply and the
Established wait were tested with a stub kubectl. velero and
kube-prometheus-stack also say "CRDs pre-applied" but both still get theirs
from Helm's native crds/ dir on FIRST install, so neither is a cold-start
blocker; CRD_HELMRELEASE makes extending this a one-liner if that changes.

fix(flux): close the substitution race — platform dependsOn root + strict substitution (P0/P1)
P0 — clusters/base/platform.yaml gains `dependsOn: [flux-system]`. This is the actual fix for the incident, not the feature gate. Verified against kustomize-controller v1.4.0 `kustomization_controller.go :: checkDependencies` (our version): dependsOn is REVISION- gated, not merely Ready-gated — when the dependency shares a GitRepository, the dependent cannot reconcile revision N until the dependency has APPLIED revision N. Applying revision N is exactly what writes a newly-added cluster-vars knob. Graph verified mechanically, not by eye: built clusters/dev and clusters/prod and walked the resulting objects. `platform` was the ONLY Kustomization without a dependsOn, and all 11 substituting Kustomizations chain transitively through it (platform-config -> platform; the waves, apps-vms, oauth2-proxy, headlamp, homepage, crafty, velero -> platform-config). The "not chaining through platform" set is EMPTY, so this one edge protects the whole graph. DFS over the full edge set after the edit: no cycles. The root (clusters/dev/ sync.yaml) runs wait: false, which is what makes the edge deadlock-free — it reaches Ready on apply success without health-gating its children. Accepted trade-off, documented in-file: the root becomes a gate. A malformed manifest anywhere under clusters/<env> — including clusters/base — now stalls platform and everything downstream, where today it would not. Fail-closed, per doctrine. P1 — StrictPostBuildSubstitutions. MY PREMISE WAS WRONG about where this belongs and it matters: this repo deliberately does NOT use `flux bootstrap` (see bootstrap/flux/README). There is no gotk-components.yaml in git, and the live kustomize-controller Deployment carries NO Flux ownership labels — it was installed imperatively by `flux install` from bootstrap.sh and is not in Flux's inventory. `flux-system` self-manages the CR graph, NOT the controllers. Nothing under clusters/** can reach a controller flag. So it uses Flux's documented mechanism for hand-installed clusters: a new bootstrap/flux/components/kustomization.yaml wrapping `gotk-components.yaml` with a JSON-6902 patch appending --feature-gates=StrictPostBuildSubstitutions=true to kustomize-controller. JSON-6902 `add /args/-` deliberately, NOT strategic merge — a container's args is atomic and a merge patch would replace all five install-generated args. bootstrap.sh step 1 now renders (`flux install --export` into a temp dir, apply the patch, ASSERT the gate string is present so a future Flux bump that breaks the patch target fails loudly) then applies. FLUX_INSTALL_PLAIN=1 is a loud escape hatch. Nothing is vendored, so components can never drift from the pinned FLUX_VERSION. Rejected: vendoring gotk-components.yaml under the root's path (the root's prune: true would put Flux's own controllers and CRDs in a prune inventory), and shipping a partial Deployment as a Flux-managed resource (a future prune would delete kustomize-controller). ROLLOUT ORDER MATTERS. P0 arrives automatically on the next reconcile. P1 does NOT arrive on a git push — the controller Deployment is outside Flux's inventory, so an operator must re-run bootstrap.sh step 1, which restarts kustomize-controller (~10-20s; Flux is level-triggered so an interrupted reconcile is simply retried). P0 must be reconciled BEFORE P1 is rolled out: with the gate on but the ordering edge absent, the same race turns a transient empty render into a transient hard Kustomization failure. ALSO FIXES A PHASE-7 BLOCKER THIS CHANGE WOULD OTHERWISE HAVE CREATED. clusters/prod had no root Kustomization — dev/sync.yaml even carried the note "a prod overlay needs its own sync.yaml -> ./clusters/prod". With the new dependsOn, a prod bootstrap would have left platform blocked forever on a flux-system Kustomization that does not exist, and nothing downstream would ever reconcile. clusters/prod/sync.yaml is now authored, mirroring dev. Two further prod-overlay gaps found and DOCUMENTED, not guessed (PROD-PROVISIONING §7): prod has no SOPS `decryption` patch (every encrypted Secret would fail to decrypt — needs the prod age-key decision, a security choice not a copy), and no GitRepository source URL patch (needs a decision on whether prod tracks the same branch as dev, which would make a dev-facing merge reconcile prod). Substitution gate re-run: check OK, 102 assertions, 0 hazards. Gate: MERGE GATE: PASS. Serves: R-ENV-02, R-GITOPS-01, R-PLAT-01, R-ENV-03.

docs: reconcile docs/comments with post-upgrade cluster state
Text-only cleanup after the upgrade campaign. Updates stale version strings, prose, and comments to the verified current facts; no Kubernetes behavior or version pins changed except the kubectl toolchain bump (below). Verified facts applied: k3s v1.36.4+k3s1, Debian 13 trixie, Cilium 1.20.1 / Gateway API v1.6.1, Longhorn 1.12.1, node RAM 24 GiB, dedicated virtio2 SSD etcd disk per node, Velero chart 12.x / v1.18, Grafana 13.2.0. - Version strings across infra/ and platform/ READMEs + comments - kubectl toolchain 1.31.4 -> 1.36.4 (devcontainer/ci/conformance versions.env; 1.31 vs a 1.36 cluster exceeded the +-1 skew) - Retired-single-apps-Kustomization refs -> apps-wave-0/1/2 + apps-vms with per-wave SOPS decryption (flux/clusters docs + bootstrap.sh) - COMPLETED/historical banners on the three executed plan docs - Resolved TODO(WS-SEC) markers -> Renovate-maintained ranges - Appended dated DECISIONS-LOG entry (2026-08-30) superseding the 2026-08-26 LIVE STATE line Left as revalidation items (not blind-edited): external-snapshotter v8.2.0 vs 1.36, Cilium ext_authz/forward-auth relevance under 1.20.1, conformance ImageVolume feature-gate assertions under 1.36.

Phase 1 (author-only): Flux + SOPS bootstrap + interface wiring (T-1.4)
bootstrap/sops (age-keygen refusing in-repo, .sops.yaml, install-age-key.sh glue installing the sops-age Secret) + bootstrap/flux (bootstrap.sh: flux install -> apply -k clusters/dev; decryption/url patches). PM wiring: place .sops.yaml at repo root (SOPS walks to root); inline the 3 flux patches into clusters/dev (avoids kustomize ../ load-restriction). clusters/dev builds with decryption enabled; full CI gate PASS. No key material; nothing executed. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]> |
