feat(helm): Support externally-managed HPAs via controller.autoscaling.horizontal.externalHPA by jmichalek132 · Pull Request #6311 · grafana/alloy

jmichalek132 · 2026-05-26T09:28:29Z

Brief description of Pull Request

Adds controller.autoscaling.horizontal.externalHPA so KEDA (and other external scalers) can own spec.replicas without fighting the chart. Default false — no behavior change for existing users.

(The configmap-key fix originally bundled here was moved to #6312 (now merged) per @kalleep's request.)

Pull Request Details

When controller.autoscaling.horizontal.externalHPA: true:

Chart omits spec.replicas from the StatefulSet / Deployment.
Chart does NOT render its own HorizontalPodAutoscaler.

Mutually exclusive with horizontal.enabled. Setting both fails the template with a clear multi-line message.

Behavior matrix:

`autoscaling.enabled`	`horizontal.enabled`	`horizontal.externalHPA`	Result
`false` (default)	`false` (default)	`false` (default)	Chart writes `replicas`. No HPA. (today's default)
`true`	(any)	`false`	Chart omits `replicas`. Renders deprecated HPA. (today's behavior)
(any)	`true`	`false`	Chart omits `replicas`. Renders new HPA. (today's behavior)
(any)	(any)	`true`	Chart omits `replicas`. No HPA rendered. (NEW)

Upgrade note: flipping externalHPA from false → true on an existing release causes a one-time single-cycle dip to 1 replica on the next helm upgrade. Helm removes the field via {"spec":{"replicas":null}}, which Kubernetes resets to default 1 (see helm/helm#12650). The external HPA corrects it within its next polling interval. Documented in the values.yaml comment.

How I tested this

Reproduced the bug (pre-fix): kind + KEDA 2.13 + Prometheus + alloy-operator + alloy chart 1.8.1. Alloy CR with controller.replicas: 5, autoscaling off, KEDA ScaledObject forcing target=10. Operator reconciles every ~15s and asserts replicas:5; KEDA briefly wins between reconciles:

19:02:52 replicas:5 ready:5   keda-hpa REPLICAS=5
19:02:57 replicas:8 ready:5   keda-hpa REPLICAS=5   <- KEDA bumps
19:03:02 replicas:5 ready:5   keda-hpa REPLICAS=5   <- operator reverts

5-min capture: replicas:5 = 59 occurrences, replicas:(8|9|10) = 1.

Patched chart (post-fix): monotonic ramp 1→5→8, stable for the rest of the capture window:

19:15:30 replicas:1 ready:1
19:15:40 replicas:5 ready:1   <- KEDA scales to minReplicaCount
19:15:55 replicas:8 ready:5   <- KEDA scales to target
... (stable replicas:8 ready:8 for 5+ minutes)
19:20:31 replicas:8 ready:8

kubectl get hpa -o name → only keda-hpa-alloy-repro. kubectl get sts alloy-repro -o yaml | yq '.spec | has("replicas")' → false.

Caveat: I ran the post-fix repro with the patched chart installed standalone, not through a patched alloy-operator image — building a custom operator image just for verification felt like overkill. The fix removes the field the operator was re-asserting on every reconcile, so the operator-level scenario should be resolved by construction. Let me know if you want me to rebuild the operator image and re-capture; happy to.

Template smoke tests (helm template):

Default values: replicas: 1, no HPA. Existing behavior unchanged.
externalHPA: true: yq '.spec | has("replicas")' → false on StatefulSet AND Deployment, no HPA.
Both flags set: helm template fails with the multi-line "mutually exclusive" message. Newlines render correctly (printf wrapping per helm/helm#9981).

ct lint: clean on all three new ci/*-values.yaml files.

ct install: the two new positive CI files install cleanly. Verified via direct helm install --wait because ct install on main is blocked by a pre-existing configmap-key-values.yaml issue (fixed in #6312 (merged)).

make generate-helm-tests: new goldens under operations/helm/tests/create-statefulset-external-hpa/ and operations/helm/tests/create-deployment-external-hpa/. Both have no spec.replicas and no HPA file.

helm-docs: README.md updated with the new externalHPA row and the upgrade-dip note.

Issue(s) fixed by this Pull Request

Fixes #6310

Notes to the Reviewer

The custom shell step in helm-test.yml (Assert external HPA validation failure) asserts that the validation file causes helm template to fail. ct doesn't have a native "this values file MUST fail" mode. The cleaner alternative is helm-unittest (which k8s-monitoring-helm uses for the same kind of thing), but that's a new tool for this chart and felt out of scope. Happy to switch if you'd prefer.

The negative CI values file intentionally drops the -values suffix so ct / make generate-helm-tests discovery skips it.

Chart.yaml not bumped — followed the existing pattern of adding to Unreleased and letting maintainers bump at release time. Tell me if I should bump it.

Local Helm was 4.2.0; CI uses 3.10.3. The committed goldens may have minor whitespace deltas from what CI renders. I'll iterate if regenerate-tests flags anything.

PR Checklist

Documentation added (values.yaml doc comment + README.md auto-generated + CHANGELOG.md entry under Unreleased)
Tests updated (3 new ci/*-values.yaml files + CI shell-step assertion + regenerated operations/helm/tests/ goldens)
Config converters updated (N/A — chart-only change)

Side fix (commit 905fe73): I noticed templates/configmap.yaml hardcoded the ConfigMap data key as config.alloy, ignoring alloy.configMap.key. The pod template DOES honor that value (via the alloy.config-map.key helper in templates/_config.tpl), so setting configMap.key: collector.yaml produced a ConfigMap with key config.alloy and a pod expecting collector.yaml — alloy crash-looped with reading config path '/etc/alloy/collector.yaml': no such file or directory. Wired the existing helper into the ConfigMap template; default behavior unchanged. Self-contained commit, easy to split if you'd rather it land separately.

Please create another pr for this and add a changelog entry for this specific fix

Done — split out to #6312 with its own CHANGELOG entry. Rebased this PR to drop the configmap commit.

### Brief description of Pull Request Split off from #6311 per [@kalleep's request](#6311 (comment)). Fixes `templates/configmap.yaml` ignoring `alloy.configMap.key`. ### Pull Request Details The chart hardcoded the ConfigMap data key as `config.alloy`, but the pod template derives the mount subPath / `--config.file` from `alloy.configMap.key` (via the `alloy.config-map.key` helper). Setting `configMap.key: collector.yaml` produced a ConfigMap with key `config.alloy` and a pod expecting `collector.yaml`: ``` reading config path '/etc/alloy/collector.yaml': no such file or directory ``` Wires the existing helper into the ConfigMap template. Default (no key set) renders `config.alloy:` unchanged. Also unblocks `ct install` on the pre-existing `configmap-key-values.yaml` test case. ### How I tested this `helm install configmap-key-verify . -f ci/configmap-key-values.yaml --wait` reaches `STATUS=deployed`; Alloy pod starts cleanly. With default values, ConfigMap key is still `config.alloy`. Golden under `operations/helm/tests/configmap-key/` regenerated (one-line change). ### Issue(s) fixed by this Pull Request N/A — surfaced during work on #6311. ### Notes to the Reviewer CHANGELOG entry uses `(#TBD)` placeholder; I'll fix up with the PR number once it's assigned. ### PR Checklist - [x] Documentation added (`CHANGELOG.md` entry under `Unreleased` > `Bug fixes`) - [x] Tests updated (golden regenerated) - [ ] Config converters updated (N/A) --------- Co-authored-by: Kalle <23356117+kalleep@users.noreply.github.com>

I think this looks ok, @petewall any input on this one?

…g.horizontal.externalHPA When set, the chart omits spec.replicas from the workload AND does not render its own HorizontalPodAutoscaler, enabling clean coexistence with external scalers such as KEDA's ScaledObject-generated HPAs. Strict validation rejects setting both horizontal.enabled and horizontal.externalHPA simultaneously. Default value is false; existing rendered manifests are byte-identical for users who do not set the new field.

Adds three values files under operations/helm/charts/alloy/ci/ covering StatefulSet, Deployment, and the mutual-exclusion validation failure case. The validation-failure file intentionally lacks the -values suffix so ct discovery skips it; an explicit CI shell step in helm-test.yml asserts that helm template fails with the expected "mutually exclusive" message — regression guard the chart-testing tool cannot provide natively. Regenerates README.md via helm-docs and the golden manifests under operations/helm/tests/ for the two positive cases. Adds a CHANGELOG entry under the Unreleased section.
