feat(ai-cluster): Istio out, cert-manager+SPIRE+Trust Manager+ESO in, new bootstrap order#4912
Conversation
…in, new bootstrap order
Changes per Aaron 2026-05-25:
- REMOVE Istio (Cilium Service Mesh covers L7 + mTLS + Gateway API)
- ADD cert-manager + SPIRE + Trust Manager + External Secrets Operator
- Reorder K3S bootstrap manifests to dependency-correct sequence:
1. Cilium (CNI + Hubble + Service Mesh + BPF MASQUERADE)
2. cert-manager (TLS for Vault)
3. Vault (secrets backend)
4. SPIRE (workload identity, chains to Vault)
5. Trust Manager (CA bundle distribution)
6. External Secrets Operator (Vault → K8s Secret sync)
7. ArgoCD (reconciles everything else)
Istio:
- Deleted k8s/applications/istio/Application.yaml + the directory
- Cilium Service Mesh (enabled below) provides the same caps
(L7-aware policy, mTLS, traffic shifting, Gateway API, ingress)
natively in the CNI agent — no Envoy sidecar per pod
Cilium (cilium/Application.yaml + bootstrap cilium-install.yaml):
- l7Proxy: true
- envoy.enabled: true
- encryption.{enabled,type,nodeEncryption} = true,wireguard,true
(node-to-node WireGuard encryption alongside the BPF MASQUERADE
spec'd originally)
- authentication.mutual.spire.enabled: false (flip after SPIRE up)
- gatewayAPI.enabled: true (replaces Istio Gateway role)
- ingressController.enabled: true + default: true (removes need
for a separate ingress-nginx Application)
New Applications (4):
cert-manager/ — jetstack helm v1.16.2, CRDs enabled
spire/ — spiffe helm v0.24.2, persistence on longhorn,
k8s + unix workload attestors, SPIFFE CSI driver
on, Vault upstreamAuthority wiring commented for
post-Vault-up flip
trust-manager/ — jetstack helm v0.15.0, lives in cert-manager ns,
ready for a Bundle CR pointing at SPIRE/Vault CA
once both healthy
external-secrets/ — community helm v0.10.7, CRDs + 3 controller
replicas, ClusterSecretStore for Vault wiring
commented for follow-up
New bootstrap manifests (5):
cert-manager-install.yaml
vault-install.yaml
spire-install.yaml
trust-manager-install.yaml
external-secrets-install.yaml
All use K3S helm.cattle.io/v1 HelmChart CRs (same pattern as the
prior cilium-install + argocd-install). K3S's Helm Controller
installs all 7 at first boot; the dependency order is documented
in the k3s-server.nix manifests block comment.
k3s-server.nix:
- Rewrote manifests block with the 7-step ordering comment
- Each manifest line groups under its layer (1/2/3/4/5/6/7)
README.md:
- Bootstrap section now lists all 7 installs with numbered order
- Applications tree rearranged: security layer (cert-manager,
vault, spire, trust-manager, external-secrets, sealed-secrets)
grouped together at the top
- Footer note: "Istio REMOVED — Cilium Service Mesh covers it"
- GitLab marked default-on / Forgejo marked manual-sync alt
(matches the prior fix-up gating)
- Ollama / vLLM still marked DEFERRED, manual-sync (matches
prior fix-up)

Enforce bootstrap ordering with explicit manifest prefixes
This change introduces a strict dependency chain (Cilium → cert-manager → Vault → SPIRE → ESO → ArgoCD), but the manifest filenames are left unprefixed while this same file notes K3S applies manifests by filename. With names like argocd-install.yaml and cert-manager-install.yaml, ArgoCD/cert-manager sort before cilium-install.yaml, so first-boot execution order does not match the declared dependency order and bootstrap can race in non-deterministic ways. Add explicit ordered targets (e.g., 00-, 10-, ...) or a real dependency mechanism so the declared sequence is actually enforced.

Avoid Longhorn PVCs in pre-Argo Vault bootstrap
The new bootstrap Vault install hardcodes storageClass: longhorn, but Longhorn is not part of the K3S bootstrap manifests and is reconciled later by ArgoCD. On fresh boot, Vault PVCs cannot bind until Longhorn exists, so Vault cannot become healthy during the pre-Argo phase that this commit depends on for SPIRE/ESO sequencing. Use a bootstrap-available storage class (or bootstrap Longhorn earlier) to prevent this dependency break.

…trate-stale-superseded empirical anchor (#4914) * shard(2026-05-25/1009Z): cold-boot — sentinel-fired-AGAIN + lior-substrate-stale-superseded empirical anchor Second 2026-05-25 fresh-session in this lane (after PR #4911 0613Z anchor). Substantively new observations: - Sentinel empty at cold-boot AGAIN (catch-43 fired AGAIN, ~4h after PR #4911 also re-armed at 0613Z); pattern: per-session non-persistence is the dominant mechanism, NOT 3-day auto-expire - 0 stuck git procs sustained ~30h since 2026-05-24 0407Z first-0-procs reading; dotgit-recovered remains stable - Cold-boot landed on peer Lior's `lior-pr-preservation-rebased` (7th+ occurrence of "lands on whoever-was-last-active's branch" failure mode) - NEW anchor: Lior's branch stages 70 `full-ai-cluster/*` files that ALREADY landed on origin/main via PRs #4910/#4912/#4913 — substrate-drift class observation; pr-triage-tiers.md Tier 1 disposition applies if Lior's branch ever pushed as PR Disposition: shard via isolated worktree on origin/main (lane-discipline preserved Lior's branch); did NOT touch Lior's WIP. Composes with the multi-anchor saturation-recovery series + the substrate-drift class documented in pr-triage-tiers.md + the catch-43 reliability of the autonomous-loop discipline. Co-Authored-By: Claude <noreply@anthropic.com> * fix(shard): correct relative-path depth (4→6) + MD038 code-span trailing-space - 7 tick-shard relative-paths used `../../../../` (4 levels) but tick shards at `docs/hygiene-history/ticks/YYYY/MM/DD/` are 6 levels deep; fixed to `../../../../../../` to match the canonical pattern - MD038 markdownlint: `A ` code span had trailing space inside backticks; reworded to `\`A\` + space` to preserve the semantic (git status 2-char code: first char `A`, second char space = staged-added with working tree matching index) without violating MD038 Both lint failures verified clean locally via markdownlint-cli2. Co-Authored-By: Claude <noreply@anthropic.com> * fix(shard): prepend 6-column pipe-row schema header + correct 105→70 staged count Addresses 2 real reviewer findings on PR #4914: 1. P0 Copilot — schema violation: first non-empty line was H1, but per docs/hygiene-history/ticks/README.md the validator at tools/hygiene/check-tick-history-shard-schema.ts requires a 6-column pipe-row first. Prepended the canonical pipe-row carrying ISO timestamp, model id, cron sentinel, body summary, PR ref, and observation. H1 body preserved below (hybrid format per B-0529 Recommendation Option 3). 2. P2 Codex + Copilot — arithmetic discrepancy: shard reported "105 staged full-ai-cluster/* additions" but the verification table later reported 70 staged. Re-counted via `git status --short | awk | sort | uniq -c`: 70 staged-A (all full-ai-cluster/*) + 35 untracked-?? (other Lior WIP) + 8 modified-M (7 PR-disc + 1 settings.json) = 113 total. The 105 was an arithmetic error (113 - 8). Corrected to substrate-honest breakdown. Both fixes verified locally: - Schema validator: shard passes (453 pre-existing violations in other shards — not introduced by this PR) - markdownlint: clean Co-Authored-By: Claude <noreply@anthropic.com> * fix(shard): split provenance commands per table metric Addresses P2 Codex finding on PR #4914: prior shard text claimed both table rows were verified via `git ls-tree -r origin/main full-ai-cluster/`, but that command only counts files on origin/main (first row). The second row (staged on Lior's branch) requires a different command (`git status --short | grep "full-ai-cluster" | wc -l` run against the contested root checkout still on lior-pr-preservation-rebased). Replaced single-command claim with a per-row verification column that names the actual command used for each metric. Both verified counts already landed correctly (70 each); only the provenance attribution was off.
