From 493ebac1d2be6a7700ad4d0fcb611753dad638f7 Mon Sep 17 00:00:00 2001 From: Benjamin Knofe-Vider Date: Thu, 4 Jun 2026 09:28:52 +0200 Subject: [PATCH] test(e2e-mw-dev): port the kind k8s suite into the real-cluster harness; retire tests/k8s MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The kind-based tests/k8s/ suite tested the multi-tenant activation pipeline against a fake cluster — it could not exercise the layers where this quarter's bugs actually lived (real Cilium, Crossplane ducklings, cnpg-shard + external RDS metadata, per-org Lakekeeper). The per-PR mw-dev harness can. Port every cluster test into harness.sh, implement the remaining TODOs, and remove the kind suite + its CI job. harness.sh (now runs kubectl in-cluster via the Job's SA token): - wire/query: SELECT 1 + 5 concurrent distinct connections - activation: DuckLake + Iceberg attach + R/W on cnpg AND ext backends - extension forks: bundled ducklake/httpfs are the PostHog forks, not upstream - worker pods: labels, securityContext (non-root/uid1000/no-priv-esc), Downward-API POD_NAME/NODE_NAME env, no ambient SA-token mount - resilience: worker-pod kill crash recovery; DuckLake durability across a worker restart; concurrent writers (fork conflict-retry) - isolation: cnpg vs ext see distinct catalogs, cross-tenant read denied - lifecycle: deprovision -> wait Duckling CR --for=delete -> re-provision the SAME org id -> R/W again (the stranded-cnpg-role regression net, now reliable because it waits on the CR's finalizer cascade instead of warehouse=deleted) run.sh: add a `janitor` subcommand; e2e-mw-dev.yml gains a 6h `schedule` trigger that runs only the janitor (reaps stale duckgres-ci-pr-* namespaces + their ducklings/cnpg-role/PIA/bindings). NAMESPACE no longer required for janitor. tests/k8s removal: - delete the kind Go suite + its testdata + CLAUDE.md (cluster tests ported; test-only harness helpers retired with it) - the RBAC + network-policy static-manifest asserts (the only unit tests over real shipped k8s/ config) move to tests/manifests/ and run in `go test ./...` - remove the k8s-integration-tests job from ci.yml The supporting k8s/ scripts/manifests + Dockerfiles are kept for now (a later cleanup PR removes the now-dangling `just test-k8s-integration` recipe). Deliberately not ported: warm-pool activation + version-reaper (per-PR CP runs warm-target=0), physical S3-prefix isolation (no list creds from the Job), Cilium egress probing (needs a stable in-worker exec) — documented in README. --- .github/workflows/ci.yml | 85 -- .github/workflows/e2e-mw-dev.yml | 44 +- CLAUDE.md | 32 +- tests/configstore/seed_sql_test.go | 2 +- .../testdata/tenant-isolation.seed.sql | 0 tests/e2e-mw-dev/README.md | 90 +- tests/e2e-mw-dev/harness.sh | 403 ++++++- tests/e2e-mw-dev/run.sh | 55 +- tests/k8s/CLAUDE.md | 103 -- tests/k8s/cache_proxy_test.go | 131 --- tests/k8s/control_plane_idle_helper_test.go | 130 --- tests/k8s/ducklake_test.go | 200 ---- tests/k8s/iceberg_test.go | 466 -------- tests/k8s/k8s_test.go | 997 ------------------ tests/k8s/port_forward_helper_test.go | 183 ---- tests/k8s/runtime_helper_test.go | 72 -- tests/k8s/runtime_helpers_test.go | 86 -- tests/k8s/setup_config_helper_test.go | 51 - tests/k8s/setup_config_test.go | 310 ------ tests/k8s/sni_test.go | 194 ---- .../k8s/tenant_isolation_diagnostics_test.go | 36 - .../tenant_isolation_diagnostics_unit_test.go | 49 - tests/k8s/tenant_isolation_helper_test.go | 368 ------- tests/k8s/tenant_isolation_test.go | 157 --- tests/k8s/worker_owner_helper_test.go | 15 - tests/k8s/worker_owner_helper_unit_test.go | 47 - tests/manifests/manifests_test.go | 112 ++ 27 files changed, 661 insertions(+), 3757 deletions(-) rename tests/{k8s => configstore}/testdata/tenant-isolation.seed.sql (100%) delete mode 100644 tests/k8s/CLAUDE.md delete mode 100644 tests/k8s/cache_proxy_test.go delete mode 100644 tests/k8s/control_plane_idle_helper_test.go delete mode 100644 tests/k8s/ducklake_test.go delete mode 100644 tests/k8s/iceberg_test.go delete mode 100644 tests/k8s/k8s_test.go delete mode 100644 tests/k8s/port_forward_helper_test.go delete mode 100644 tests/k8s/runtime_helper_test.go delete mode 100644 tests/k8s/runtime_helpers_test.go delete mode 100644 tests/k8s/setup_config_helper_test.go delete mode 100644 tests/k8s/setup_config_test.go delete mode 100644 tests/k8s/sni_test.go delete mode 100644 tests/k8s/tenant_isolation_diagnostics_test.go delete mode 100644 tests/k8s/tenant_isolation_diagnostics_unit_test.go delete mode 100644 tests/k8s/tenant_isolation_helper_test.go delete mode 100644 tests/k8s/tenant_isolation_test.go delete mode 100644 tests/k8s/worker_owner_helper_test.go delete mode 100644 tests/k8s/worker_owner_helper_unit_test.go create mode 100644 tests/manifests/manifests_test.go diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index ead0eb2b..9f894817 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -247,88 +247,3 @@ jobs: - name: Run Kubernetes-tagged control plane package tests run: just test-controlplane-k8s - - k8s-integration-tests: - needs: unit-tests - runs-on: ubuntu-24.04-arm - timeout-minutes: 30 - # id-token: write lets this job request a GitHub OIDC token, which - # aws-actions/configure-aws-credentials trades for STS-vended AWS - # credentials by assuming github-duckgres-iceberg-ci-testing-role in mw-dev. - # The role's trust policy is scoped to repo:PostHog/duckgres:*; its - # IAM policy is scoped to the iceberg test buckets only.
