Lift the e2e suite onto the prod-fidelity two-cluster env (#226)

[ecv]

Goal

Run the existing e2e suite (test/e2e/) against the prod-fidelity two-cluster environment stood up in #226, instead of the single-stack bridge harness on main.

Today the suite runs via the Makefile bridge path (make kind-standard-cluster + make kind-infra-cluster + make prepare-infra-cluster + make test-e2e) — the stopgap landed in #268 to unblock CI. #226 introduces the canonical env (task test-infra:up: two clusters, EG v1.7.4, the ext-server, the real Coraza data plane, optional Karmada host). This issue tracks lifting the suite onto that env so the arc (#247) has a real place to prove edge behavior, en route to #248 wiring it into CI.

Why it's small

The suite binds to a data-plane contract that #226's env already satisfies with identical names:

Test binds to	bridge (main)	#226 env
downstream gateway namespace	datum-downstream-gateway	datum-downstream-gateway
GatewayClass / EnvoyProxy	datum-downstream-gateway	datum-downstream-gateway
controllerName	gateway.envoyproxy.io/datum-downstream-gateway	same
Coraza WAF EnvoyProxy	datum-downstream-gateway	datum-downstream-gateway
namespace watch label	meta.datumapis.com/upstream-cluster-name	same

Only real divergences:

• Cluster names. Tests use the chainsaw aliases nso-standard / nso-infra; Stand up a test environment that mirrors how the edge really runs #226's kind clusters are nso-upstream / nso-downstream. Aliases are set at invocation (--cluster alias=kubeconfig), not baked into the tests — pure plumbing.
• Ext-server namespace is network-services-operator-system in Stand up a test environment that mirrors how the edge really runs #226 vs datum-downstream-gateway in the bridge. Invisible to the tests — they only reach the ext-server through EG's extensionManager wiring, which Stand up a test environment that mirrors how the edge really runs #226 already stands up.

Scope

1. Add a test-infra:test-e2e task: after test-infra:up, run chainsaw test ./test/e2e --cluster nso-standard=<nso-upstream kubeconfig> --cluster nso-infra=<nso-downstream kubeconfig>.
2. Bring the current main test/e2e/ suite onto the Stand up a test environment that mirrors how the edge really runs #226 branch (it's 70+ commits behind and carries the older tests; the suite was hardened recently in 1722a30 / 69d07c5).
3. Confirm upstream-delivered fixtures (Gateway / HTTPRoute / TrafficProtectionPolicy) reconcile through Stand up a test environment that mirrors how the edge really runs #226's prepare-upstream + link-clusters replication path.

No test rewrites expected — the contract matches. Est. plumbing ~1–2h.

The real risk is runtime, not code

Wiring the suite up is not the same as getting it green. The bridge's own repro (#268) was waf-gw stuck at Programmed=Unknown — the data plane never installed. #226 claims to fix exactly that (EG v1.7.4 pin, maxMessageSize: 256Mi, failOpen: false, includeAll: true). Whether it actually programs under this suite is the open question, and only a live task test-infra:up + run answers it. That verification is the point of this work.

Acceptance

• test-infra:test-e2e task runs the full test/e2e/ suite against the Stand up a test environment that mirrors how the edge really runs #226 two-cluster env.
• waf-gw reaches Programmed=True (not Unknown) in the env.
• Report per-test pass/fail; the WAF-serves-traffic + paranoia-validation TPP tests pass on the real Coraza data path.
• Document any test that needs an env-specific adjustment (and why).

Status update

Acceptance criteria

• test-infra:test-e2e task runs the full test/e2e/ suite against the two-cluster env. Added on test/issue-275-e2e-on-prod-fidelity (22f9a0c) — maps the chainsaw aliases nso-standard/nso-infra onto the env's upstream/downstream kubeconfigs, --report-format JSON so a hang leaves a trail. CLI_ARGS selects a single scenario.
• waf-gw reaches Programmed=True (not Unknown). Confirmed live: Programmed=True, benign traffic returns 200 on the real Coraza data path. The fix: install downstream WAF data plane in e2e CI (#263) #268 Programmed=Unknown failure did not reproduce — root cause there was a GatewayClass name mismatch (test hardcoded datum-downstream-gateway; the env installs datum-downstream-gateway-e2e), fixed in fcf3f77, not a data-plane defect.
• Per-test pass/fail reported; WAF-serves + paranoia-validation TPP pass on the real Coraza path. Both green — see matrix below.
• Document any test needing an env-specific adjustment. Below.

Suite result (against the rebased prod-fidelity env)

4 pass / 2 fail.

Test	Result	Note
trafficprotectionpolicy-enforce-serves-traffic	✅ PASS	crux — waf-gw programs, traffic 200
trafficprotectionpolicy-paranoia-validation	✅ PASS	needed #257/#251 on base
gateway-listener-hostname-collision	✅ PASS	needed #219 on base
ready-when-context-is-ready	✅ PASS
gateway-accepted	❌ FAIL	self-provisions data plane — see below
gateway-invalid-certificate	❌ FAIL	self-provisions data plane — see below

Env-specific adjustments

1. GatewayClass name. The env installs datum-downstream-gateway-e2e; the enforce test hardcoded the bare datum-downstream-gateway. Aligned the test (fcf3f77). The issue's original "identical names" table was inaccurate on this point — the env suffixes -e2e.
2. Stale operator image. The env branch (Stand up a test environment that mirrors how the edge really runs #226) was ~70 commits behind main, pinning a build that predated Gateway: hostname-less tenant listeners rejected with misleading 'must be unique' (default-listener injection collision) #219 (clear hostname message) and TrafficProtectionPolicy CRD rejected: paranoiaLevels default {} violates detection>=blocking CEL rule #257 (TPP paranoia default/validation). Rebased Stand up a test environment that mirrors how the edge really runs #226 onto main on test/prod-fidelity-env-rebased → draft PR test(infra): prod-fidelity edge test env + e2e suite #276 (supersedes Stand up a test environment that mirrors how the edge really runs #226). Rebuilding the operator from that branch flipped hostname-collision and paranoia-validation green (2 pass → 4 pass).

Remaining work

The two failures are not name/image issues — they self-provision a per-test GatewayClass + EnvoyProxy in envoy-gateway-system, which this shared-data-plane env does not host. Options: rework them to target the shared data plane (→ 6/6), or scope this issue to the 4 passing and track the self-provisioning pair separately.

Artifacts

• Suite task + tests + name-align: branch test/issue-275-e2e-on-prod-fidelity
• Env rebased onto main: PR test(infra): prod-fidelity edge test env + e2e suite #276 (draft)

CI-vs-env path gap (blocking the combined PR #276)

The combined PR runs 8/8 green on the two-cluster env but fails the CI E2E Tests gate, because the two exercise the same test/e2e suite through different setup paths:

	Setup path	Clusters
Our env (validated)	task test-infra:up + test-infra:test-e2e	nso-upstream / nso-downstream
CI gate (test-e2e.yml)	make kind-standard-cluster + make kind-infra-cluster + make prepare-e2e + make prepare-infra-cluster + make test-e2e	nso-standard / nso-infra

Both apply the shared config/e2e + config/e2e-downstream, but the env does extra setup in the Taskfile that the bridge make-targets never run. The shared-plane test rework removed the compensating per-test setup, so the bridge now diverges:

1. datum-downstream-gateway-hostnames namespace — the env creates it (downstream-namespaces task); the bridge previously relied on the tests creating it, which the rework dropped. Result on CI: namespaces "datum-downstream-gateway-hostnames" not found, the gateway never publishes a Hostname address, and gateway-accepted / gateway-invalid-certificate fail their address asserts.
2. eppEmissionEnabled: false — the env patches it live via prepare-upstream; config/e2e/config.yaml omits it, so on the bridge NSO also emits its own EnvoyPatchPolicy and errors an empty namespace may not be set (empty downstreamGatewayNamespace).

Root cause: env-only setup lives in the Taskfile, not in shared config the bridge also applies — so cluster state diverges despite shared manifests.

Convergence options

• A — point CI at the env. Replace the bridge steps in test-e2e.yml with task test-infra:up + test-infra:test-e2e. One path, exactly the setup proven 8/8. Overlaps Run edge e2e in CI against the real federated architecture #248 (CI against the federated arch).
• B — make the bridge mirror the env. Move the env-only setup (hostname namespace, eppEmissionEnabled: false) into shared config/manifests both paths apply. Keeps the bridge harness; smaller change, but two harnesses remain.

Per the "same path" goal, proceeding with A — it reuses the validated env path and retires the divergence rather than papering over it.

CI convergence landed; two open items

Per the "same path" decision, CI now runs the prod-fidelity env instead of the bridge. On test/prod-fidelity-env-rebased (PR #276):

• test-e2e.yml rewritten to task test-infra:up + task test-infra:test-e2e (installs task + helm + pinned tools).
• Bridge retired: Taskfile.dev.yaml, its Makefile targets, config/tools/kind/{standard,infra}-cluster.yaml, and the orphaned config/e2e-downstream/{pki,waf-gateway,extension-server-config}.yaml.
• Pinned kind bumped to v0.32.0 (matches the env's node image).
• Docs updated (CLAUDE.md + extension-server enhancement) plus authoring guidance: bind to the env's shared data plane, provision scenario dependencies in test-infra:up, push workflow edits over SSH.

Open item 1 — E2E run is gated

Modifying .github/workflows/test-e2e.yml makes GitHub hold the PR's E2E run pending approval; it does not auto-trigger (an empty-commit nudge didn't clear it). Needs an approve/re-run in the Actions tab. The env-in-CI path is unverified and will likely need a round or two of iteration (action allowlist, tool install, timeouts).

Open item 2 — trunk rebase blocked by billing drift (needs a decision)

main advanced ~147 commits; #239 (billing pipeline) merged and added test/e2e/billing/chainsaw-test.yaml plus a billing-usage-collector install wired into the bridge's prepare-infra-cluster. Because CI now runs chainsaw ./test/e2e on the env, the billing scenario runs on the env — but the env doesn't install the collector, so it would fail. (#239's other two additions, extension-server and EG extensionManager, the env already provides.)

Convergence needs billing-usage-collector ported into test-infra:up. Options: (a) port it into the env (verify test/e2e/billing green, then finish the rebase); (b) exclude test/e2e/billing and flag the billing owner; (c) keep the bridge solely for billing (abandons convergence). Rebase is paused (aborted to a clean state) pending this call.

Note

Workflow-file pushes require SSH — the gh HTTPS token lacks the workflow scope.

[ecv]

Done — delivered by #276 (merged), which lifts the full test/e2e/ suite onto the prod-fidelity two-cluster env and runs it in CI via test-e2e.yml (commit e2c1296 retired the single-stack bridge from #268).

All four acceptance criteria are met, and the E2E Tests workflow is green on the latest main. Closing.

Remaining edge-arc follow-ups tracked separately: #227 (control-plane→edge policy delivery) and #248 (federated Karmada CI).
