`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.

home-network-k3s-impl
Implementation of the home k3s + Longhorn platform. This repo holds the reconciled artifacts
(Flux config, Kustomize overlays, KubeVirt/Helm manifests, ServiceDefinitions, Kyverno policies,
Chainsaw conformance tests, CI). It is driven by — and subordinate to — the read-only
specification at ../home-network-k3s.
Rules (from the spec — non-negotiable)
- The spec is read-only. Never modify anything under
../home-network-k3s. Implement against it; escalate spec problems, don't edit them (specAGENTS.md§11, R-TEST-06). - Done = a green, reproducible, requirement-tagged conformance test — never "merged," never a
manual demo (spec
docs/14,agents/definition-of-done.md). - No work on
main. Every change is a feature branch merged intomain(specCONTRIBUTING.md). - No plaintext secrets — SOPS-encrypted only (spec
docs/07). - Phase discipline — only build what the active roadmap phase authorizes (spec
roadmap/phases.md).
Layout
infra/ node provisioning: OpenTofu (Proxmox VE) + cloud-init + Ansible, and the
pinned dev container that carries the whole toolchain
bootstrap/ one-time cluster bootstrap: Flux install, SOPS/age key, host Gitea
platform/ platform CONTROLLERS (Flux HelmReleases / operator bases): kyverno, cilium,
longhorn, external-snapshotter, cert-manager, externaldns, gateway, coredns,
vpn-egress, monitoring, cnpg, keycloak, oauth2-proxy, kubevirt
platform-config/ platform CONFIGS — the custom resources of the CRDs installed above
(ClusterIssuers, Gateway, Kyverno policies, KubeVirt/CDI CRs, Keycloak CRs).
Split out because CRs and the CRDs they use cannot apply in one pass.
apps/ application tier, reconciled as dependency-ordered WAVES:
wave-0/ wave-1/ wave-2/ rendered container apps (see DESIGN-waves.md)
vms/ KubeVirt VirtualMachines (non-gating tier)
catalog/ ServiceDefinition entries (the onboarding surface) + render.py
schemas/ ServiceDefinition JSON Schema + renderer contract
clusters/ Flux entrypoints + dev/ and prod/ overlays
conformance/ Chainsaw behavior/conformance suite + harness + coverage report
ci/ the gate as scripts (lint · schema · Kyverno L0 · L1 render · decision)
.gitea/ Gitea Actions CI running that gate on an in-cluster runner
Status
Roadmap phases 0–6 are delivered and deployed on the dev cluster; Phase 7 (prod) is not
open — clusters/prod is a design-only overlay.
| Phase | Delivered |
|---|---|
| 0 Foundations | ServiceDefinition schema + renderer, Kyverno L0 gate, conformance harness, CI |
| 1 Cluster bring-up | 3-node k3s HA on Proxmox VE (192.168.1.50/.51/.52), Cilium, Flux, SOPS |
| 2 Platform core | Cilium · Longhorn · cert-manager (LE-prod wildcard) · ExternalDNS · Gateway API · split-horizon CoreDNS |
| 3 Egress / VPN | ADR-0015 node-level OpenVPN split-tunnel + Cilium egress-gateway steering + host kill-switch |
| 4 Observability | kube-prometheus-stack · Loki · Alloy · Alertmanager. Velero still blocked on OQ-BKP; image-automation authored but disabled |
| 5 IaaS | KubeVirt + CDI on real nested KVM; live-migratable RWX VM storage. The UniFi VM runs, but UniFi OS Server is not yet installed in the guest |
| 6 Identity + CI | Keycloak (Operator + CNPG) · oauth2-proxy forward-auth · Grafana OIDC · kubectl OIDC SSO with group→RBAC · in-cluster Gitea Actions merge gate |
Conformance: 36 / 51 requirements covered (70.6%), 15 gaps, 1 safety-critical gap
(R-STATE-02, Longhorn node-loss). Regenerate with ./conformance/run.sh --coverage-only;
the full report is conformance/_artifacts/coverage/coverage.md.
The running narrative — decisions, root causes, incidents, follow-ups — is
DECISIONS-LOG.md. It, not this table, is the authoritative record.
Working on this repo
Everything the gate needs is baked into the pinned dev container — do not install the toolchain on the host:
infra/devcontainer/dev.sh build # once
infra/devcontainer/dev.sh run make -C ci gate # the same gate CI runs
infra/devcontainer/dev.sh # interactive shell (sops, flux, kubectl, tofu, ansible)
The container mounts the repo at /work, your age keyring, and the sibling spec repo read-only
so the spec-immutability check can actually run. See
infra/devcontainer/README.md.
A green run prints MERGE GATE: PASS. The L2/L3 conformance layers stay SKIPPED unless
CLUSTER_AVAILABLE=true — the static gate never pretends to have run them.
