ci(e2e): run tests in parallel with a label matrix - #373
Conversation
Split the serial e2e run into a GitHub Actions matrix, one job per label bucket (Ginkgo --label-filter), with a derived catch-all job covering the rest. Buckets are defined once in the Makefile (E2E_BUCKETS); a test-e2e-verify-buckets target fails if any test matches two buckets. Build the operator image once in a prepare job and share it to each matrix job as an artifact, so jobs load it instead of re-running docker-build. The suite skips its in-suite build when E2E_SKIP_IMAGE_BUILD=true and reads the tag from E2E_MANAGER_IMAGE. Reduces e2e wall time from ~20m to ~13m (buckets use existing labels only; rebalancing the currently-unlabeled tests is a follow-up). Signed-off-by: Björn Svensson <bjorn.a.svensson@est.tech>

…es (#379) ### Summary The teardown spec in the `ValkeyCluster` Ordered container asserts on a different cluster than the one it deletes, so it passes while the cluster it claims to have removed is still running. ### Features / Behaviour Changes Test only. No operator behaviour changes. ### Implementation "deletes the Valkey Cluster deployment" deletes `config/samples/v1alpha1_valkeycluster.yaml`, which is `cluster-sample`, then asserts on the shared `valkeyClusterName`. That variable is declared once for the whole Ordered container and reassigned by the scale-out and scale-in specs that run before it (lines 669 and 792 on `main`), so by the time the teardown spec runs it holds `valkeycluster-scalein`. The scale-in spec already deleted that cluster in its own `defer` with `--wait=false`. All four `Eventually` blocks (CR, Service, ConfigMap, ValkeyNodes) therefore check a cluster that is already gone, and removal of `cluster-sample` is never verified. Under a label-filtered run, which #373 is heading toward, the variable would be empty and the assertions would pass vacuously again. This names the cluster in the spec so the assertions describe what the spec actually deletes. ### Limitations This fixes the one spec. The wider coupling is still there: `valkeyClusterName` is shared across the container and reassigned by three specs, which is what makes the container impossible to split by label. I wrote that up in #371 and can follow up with the decoupling if the approach looks right. ### Testing Verified on a local k3d cluster, running the assertions exactly as the spec does. With `cluster-sample` present and its Service, ConfigMap and six ValkeyNodes all live, the old assertions (against `valkeycluster-scalein`) pass 4 out of 4, which is the bug: the spec is green while the cluster it should be checking is still up. After `kubectl delete -f config/samples/v1alpha1_valkeycluster.yaml`, the new assertions (against `cluster-sample`) pass 4 out of 4. The cascade does not depend on the operator: the ValkeyCluster carries no finalizers, and the Service, ConfigMap and ValkeyNodes all have `ownerReferences` pointing at it, so the API server garbage collects them. ### Checklist - [x] This Pull Request is related to one issue. - [x] Commit message explains what changed and why - [x] Tests are added or updated. - [ ] Documentation files are updated. - [x] I have run pre-commit locally (`pre-commit run --all-files` or hooks on commit) Signed-off-by: melancholictheory <selimvhorst@gmail.com> Co-authored-by: Björn Svensson <bjorn.a.svensson@est.tech>

Have we considered using Ginkgo's built-in parallel execution (-p / -procs) instead of maintaining these buckets? Also, with the current approach, each bucket runs on a separate GitHub Actions runner and creates its own Kind cluster. With 4–5 buckets, we're effectively running 4–5 Kind clusters in parallel. Could this add up high CI/resource cost compared with running multiple Ginkgo processes within a single Kind cluster? |

Summary
Splits the serial E2E job into a parallel GitHub Actions matrix (one job per label bucket) and builds the operator image once, sharing it to the matrix jobs as an artifact.
