feat(devcontainer): bake velero CLI into the toolbox, pinned to prod server v1.18.2
The velero CLI and server are version-coupled, so VELERO_VERSION follows the server running on prod (docker.io/velero/velero:v1.18.2, chart 12.2.3, verified 2026-11-07). It has no renovate marker on purpose: bump it together with the chart's appVersion. The verify stage asserts that `velero version --client-only` reports the pin. The build arg reaches CI through build-image.sh --print-build-args, so no .gitea/ or ci/ change is needed. Co-Authored-By: Claude Opus 5.5 <[email protected]> |

docs(runbooks): the PR flow, not git push origin main -- that instruction is now blocked
main became a protected branch on 2026-09-29, so the direct push that 37 of 39 runbooks instructed is REJECTED. The wording was merely stale before; it is now actively wrong, and it is the line an operator reads mid-incident. Every occurrence now describes the real path: push a branch, open a PR, merge once the gate is green -- that merge is the deploy. 35 files shared one identical block; flux-reconcile.md, README.md and plex-claim.md each said it their own way and were corrected individually. plex-claim.md is rewritten around the delivery loop and records that THE SERVER IS NOW CLAIMED (PlexOnlineToken present in /config), so PLEX_CLAIM is a permanent no-op and the page only applies after a /config wipe. Adds infra/plex/claim-ship.sh, which drives branch -> commit -> push -> PR -> gate -> merge -> reconcile -> pod roll -> verdict with a stopwatch. Three steps are easy to lose under time pressure and two are SILENT when skipped: --with-source (without it the Kustomization applies the previously-fetched revision), the mandatory rollout restart (only the ciphertext changes, so the pod template is byte-identical and nothing restarts itself), and the feat/ branch prefix (act_runner capacity is 1, and a prefix inside gate.yml's push trigger fires a redundant run that serialises ahead of the PR run). Drops the "~4-minute TTL" the page asserted in four places. It was uncited, and upstream pms-docker documents no expiry at all. The countdown on plex.tv/claim is the authority. Measured loop: ~2m45s. DECISIONS-LOG carries the PM handoff: both halves of the 2026-08-31 CI claim were false, the stale-.runner root cause, the four-deep Flux dependency cascade, and the correction that a skipped Gitea job reports success rather than hanging.

fix(runbooks): declare whole-repo scope, drop the bespoke l0 stage, +cnpg-primary-spread
Three corrections after rebasing onto main. 1. THE GUARD CAUGHT A REAL ONE ON ITS FIRST CONTACT WITH main. main had gained `CNPGPrimariesCoLocated` (platform/cnpg/alerts.yaml) pointing at /runbooks/cnpg-primary-spread, with no runbook. The check failed the rebase exactly as designed — 46 annotations, 35 names, 34 present — naming both the missing file AND the missing configMapGenerator entry. runbooks/cnpg-primary-spread.md now exists: what co-located primaries actually cost here (blast radius, not an outage, because instances: 3 + required anti-affinity), why the drift is uncorrectable-by-declaration (CNPG has no primary-placement field), the readiness gate that keeps the rule quiet during a real node outage, and the ~9s-per-database switchover rebalance, one cluster at a time. The 2026-09-07 outage in which all three primaries sat on one node is the reason the alert exists at all. 2. WHOLE-REPO SCOPE, NOT A HAND-WRITTEN STAGE. main's refactor replaced ci/l0.sh's per-check "UNCONDITIONAL" stages with a declaration: `conformance.home.k3s/scope: "whole-repo"`, unioned into every gate run by Stage 3b's `--include-scope`. My +38-line Stage 3f is removed (ci/l0.sh is now byte-identical to main) and the annotation is declared instead. Assertion (7) of the check was rewritten to match: it no longer asserts its own path appears in ci/l0.sh — it asserts the test DECLARES the scope and that ci/l0.sh still passes --include-scope, since neither half alone makes the check load-bearing. That matters here because ci/touched-requirements.sh maps platform/monitoring/* to "R-OBS-01 R-OBS-02", not R-OBS-04, and maps platform/kubevirt/* and runbooks/* to nothing at all. 3. A FACTUAL CORRECTION IN ALL 35 RUNBOOKS. Every page claimed `dev.sh` defaults its current-context to k3s-dev. main's `9b4744d fix(devcontainer): dev.sh defaults to prod` made that false, and a runbook that misstates which cluster a command talks to is worse than one that says nothing. The pages now say what is durably true: the default has already changed once, so naming `--context k3s-prod` is what makes a command mean the same thing next month, and the per-invocation banner is there to be read. The check's own failure message was corrected the same way. Re-verified after all three: check green at 374 assertions (46 annotations, 35/35 runbooks present, 35/35 projected), re-applied to prod, and re-probed in-cluster through the Gateway — node-down, keycloak-down, keycloak-client-secrets, cnpg-archiving, longhorn-faulted, vpn-down, node-io and cnpg-primary-spread all HTTP 200 with text/plain; charset=utf-8 and 8.9-12.1 KB of real body; /runbooks/ index 200; an unknown name 404s with a pointer rather than a blank page; and homepage still answers the apex `/`, confirming Gateway API longest-path precedence. Full merge gate: PASS (spec-immutability, lint, l0, render-golden, l1 all green; prom-rules SKIPPED for want of promtool in the image; L2/L3 SKIPPED, no cluster).

feat(runbooks): make the 42 alert runbook_url annotations resolve
Every platform-health alert rule carries `runbook_url: "https://${BASE_DOMAIN}/runbooks/<name>"` — 42 annotations over 34 distinct names, across platform/monitoring/alerts.yaml, platform/monitoring/pvc-capacity-alerts.yaml, platform/cnpg/alerts.yaml and platform/kubevirt/alerts.yaml. There was no runbooks/ directory and no HTTPRoute serving that path: an in-cluster probe of https://home.keithjackson.dev/runbooks/node-down returned HTTP 404. Every alert that reached a human handed them a dead link at the exact moment the documentation is read, and the annotation made it look solved — the same green-surface-over-absent-mechanism class as the import Job that reported success while storing placeholder secrets. No alerts.yaml is touched and no runbook_url value changes. The existing URL scheme is made to resolve instead. WHAT LANDS - runbooks/<34>.md — one per name, each grounded in this cluster's real topology and, where one exists, its real incident history: the 2026-09-07 k3s-prod-1 etcd I/O starvation (measured PSI 11.36 vs 0.75/1.29, the exact journal lines, the four mechanisms proven inert), the Longhorn reboot tax and the freeze/thaw of concurrent-replica-rebuild-per-node-limit, Cilium's once-resolved egress interface cache (Ifindex 3 against a live 1780) and the absence of OSS failover, the CNPG 38-hour ContinuousArchiving=False with its measured 6.8 MiB/h disk-full clock and the 2026-09-12 aggregation-scope fix, the 2026-09-06 Keycloak lockout in which all 12 clients held literal placeholder secrets behind an entirely green cluster, the Velero R2 x-amz-tagging NotImplemented incompatibility and its v1.14.3-rc.2 pin, and swap re-enabling itself across reboots via systemd-gpt-auto-generator. Each page states what the alert means HERE, the first diagnostic commands, likely causes ordered by probability with a remediation each, and when to escalate or stop. - Every page uses FULLY-QUALIFIED resource names and says why: three CRDs register the kind `Backup` here, the bare short name resolves to Longhorn's (zero objects), so `kubectl get backup -A` prints "No resources found" on a cluster holding 6 Velero and 27 CNPG backups. Acting on that false negative is how a CLI quirk becomes data loss. - Every page states that kubectl only works via `infra/devcontainer/dev.sh run bash -c '...'` with an explicit `--context k3s-prod`, because dev.sh defaults its current-context to k3s-dev. - Pages also record which alert groups are INERT today (measured 2026-09-13: no Longhorn, cert-manager, Flux-controller or Hubble scrape job exists, so 13 rules evaluate against nothing) so nobody reads their silence as health. SERVING — runbooks/serving/ plus clusters/base/runbooks.yaml A two-replica nginx-unprivileged serving a ConfigMap generated from runbooks/*.md, at the apex `/runbooks` prefix, in its own non-gating post-platform Flux tier (dependsOn platform-config, wait:false) — the platform/homepage pattern, file for file. - The service catalog cannot express this route: ingressRoutes[].host is pattern-bound to a single DNS label plus the apex, so the bare apex is unrepresentable, and there is no path field. - Rejected: redirecting to the Gitea web UI. A runbook is read when the platform is broken, and Gitea is an app-tier workload whose own dependencies several of these runbooks document; Gateway API's RequestRedirect also has no "append .md" modifier, so it would need 34 hand-maintained ReplaceFullPath rules. - configMapGenerator maps each file to an EXTENSIONLESS key (node-down=node-down.md), so /runbooks/node-down is a plain static lookup with no rewrite rule. Served as text/plain: the namespace has DNS-only egress, so a CDN markdown renderer could not load anyway. - The tier declares NO postBuild.substituteFrom, deliberately: envsubst would run over the prose and silently empty every ${...} shell example (it fails open — the 2026-09-01 emptied Cilium k8sServiceHost). The HTTPRoute omits `hostnames:` and inherits the https-apex listener's, so nothing needs substituting. AUTH — PUBLIC, deliberately auth-mode=none. Gating these pages behind oauth2-proxy/Keycloak would make runbooks/keycloak-down unreadable when Keycloak is down and runbooks/keycloak-client-secrets unreadable during the exact 2026-09-06 failure mode. An operator who cannot log in is this route's primary reader. Content is operational procedure only, no secrets. The rationale is recorded in an annotation on the HTTPRoute so the route is left OUT of the Gateway ext-authz attachment when forward-auth enforcement lands. PROVEN — in-cluster probe through the Gateway on prod /runbooks/node-down HTTP 200 8613 bytes text/plain; charset=utf-8 /runbooks/keycloak-down HTTP 200 9378 bytes text/plain; charset=utf-8 /runbooks/cnpg-archiving HTTP 200 11729 bytes text/plain; charset=utf-8 /runbooks/longhorn-faulted HTTP 200 9135 bytes text/plain; charset=utf-8 /runbooks/vpn-down HTTP 200 11092 bytes text/plain; charset=utf-8 /runbooks/backup-failure HTTP 200 9604 bytes text/plain; charset=utf-8 HTTPRoute Accepted by io.cilium/gateway-controller on sectionName https-apex; the `/runbooks` prefix wins over homepage's apex `/` by Gateway API longest-path precedence. GUARD — conformance/tests/l0-static/alert-runbooks-resolvable (R-OBS-04) 363 offline assertions. It checks BOTH halves, because the regression is silent in both directions: an alert with a new runbook_url and no runbook links to a 404, AND a runbook committed without its configMapGenerator entry is in git, reviewed, merged, and still 404s in the cluster. Also asserts a quality floor so a stub cannot make the link look fixed, and that route/listener/nginx prefix agree with the annotations. Proven to fail, then reverted: a bogus runbook_url (2 FAIL), a runbook removed from the generator (1 FAIL), and a 31-byte stub (7 FAIL). Co-Authored-By: Claude Opus 5 <[email protected]> |
