gate / gate (pull_request) Failing after 1m51s
gate / conformance (pull_request) Has been skipped
fix(obs): open 44180 to ns monitoring so the forward-auth gate sidecars are actually scrapable
platform/oauth2-proxy/podmonitor.yaml landed 2026-10-02 and discovered six targets that
have never once scraped. Measured on prod 2026-10-04: all six read health=down with
lastError "context deadline exceeded" and lastScrapeDuration exactly 10.0s — the
configured scrapeTimeout, i.e. packets DROPPED rather than refused.

Cause: every app namespace ships a default-deny NetworkPolicy with
policyTypes: [Ingress, Egress] and NO ingress key at all (deny-all-ingress), and the only
ingress allowance is <app>-allow-gateway-ingress: fromEntities: [ingress] -> 4180.
Prometheus matched no clause. Verified identical in all six of jackett, radarr, sonarr,
qbittorrent, pihole, crafty; zero namespaces had any -allow-monitoring-scrape object.

render.py already had the right idiom — r_monitoring_ingress_policy — but it returned None
unless the service declared observability.metricsEndpoint, and NO ServiceDefinition in this
catalog declares one. It was wired in at the call site and had never emitted a single
object on any branch: correct, and entirely latent.

It now also fires for the forward-auth gate sidecar's own metrics port, keyed on
_needs_oauth2_sidecar — deliberately the same condition the scrape keys on, since
podmonitor.yaml selects pods purely by the auth-mode label, so a target exists iff the
sidecar exists. Keying on observability.metrics instead would let metrics: false produce a
discovered-but-blocked target: the same "two halves authored apart" failure this function
exists to prevent.

Rendered here rather than in platform/oauth2-proxy because that tier would have to name app
namespaces created by the sibling apps-wave-0/1 tiers — it would apply on a running cluster
and fail on a cold bootstrap. podmonitor.yaml's header records that objection; rendering
per-app dissolves it.

Five CNPs result, one per forward-auth app, each opening only 44180 to only ns monitoring.
apps/ re-rendered with the invocation it was generated by (--no-image-automation, verified
byte-identical beforehand); --emit-waves deliberately not run, so no wave kustomization moved.

Three L1 goldens are regenerated with it (+63 lines, -0): a renderer change that adds an
object necessarily drifts the goldens that pin the renderer's output. The first gate run
caught container-workload-render and egress-class-render as FAIL with exactly this CNP as
the drift. default-deny-baseline-render's golden regenerated byte-identical, which is the
evidence that the regen is faithful and not a rubber stamp.

That puts conformance/** in the diff, which is a sensitive path: this PR needs a non-author
approving review. The local gate cannot see that — offline it reports approval-policy green
(N/A).

Local toolbox gate: rc 3 UNDETERMINED, not 0. Every stage that ran is green and l1 went
FAIL -> pass with the goldens; the only not-run stage is gitea-settings (no
GITEA_SETTINGS_TOKEN). L2/L3 conformance is UNVERIFIED for all 8 touched requirements.

Not verified: that the scrape now succeeds. Nothing is applied until Flux reconciles main.

apps

App-tier manifests, rendered from catalog/*.yaml ServiceDefinitions by catalog/render.py and split into dependency-ordered waves (wave-<N>/).

  • Each wave-<N>/ is reconciled by its own Flux Kustomization apps-wave-<N> (clusters/base/apps-wave-<N>.yaml), which dependsOn wave N-1 (wave 0 dependsOn platform-config) and health-gates (wait: true) ONLY that wave. A crashlooping workload in a later wave can no longer stall an earlier wave or block new revisions.
  • wave-<N>/kustomization.yaml and clusters/base/apps-wave-<N>.yaml are generated — run python3 catalog/render.py --emit-waves after onboarding a service; do not hand-edit them.
  • Wave assignment = longest dependency-path depth over the catalog dependencies: graph; a co-located CNPG database <svc>-db is a leaf and always lands strictly below its consumer.

See ../DESIGN-waves.md for the wave table, Flux topology, and the cutover runbook.
