Contribution Type

Feature — Add production-ready Kubernetes Helm chart

Problem / Use Case

RocketRide Server has Docker support (docker/Dockerfile.engine) but no Kubernetes deployment manifests. Teams wanting to deploy RocketRide in production Kubernetes clusters must write their own manifests from scratch — configuring deployments, services, health probes, autoscaling, secrets, and optional dependencies (PostgreSQL, ChromaDB) manually.

Proposed Solution

A complete Helm chart at deploy/helm/rocketride/ with 16 files:

  1. Engine Deployment — Configurable replicas, resource limits, readiness/liveness/startup probes on /ping:5565, security contexts (non-root, drop ALL capabilities)
  2. HPA — Conditional HorizontalPodAutoscaler with CPU/memory targets
  3. Ingress — Conditional with TLS, className, annotations
  4. ConfigMap + Secret — Non-sensitive config separated from credentials, existingSecret pattern for production
  5. ServiceAccount — With IAM role annotation support (AWS IRSA, GCP Workload Identity)
  6. PostgreSQL StatefulSet — Optional, ankane/pgvector:v0.8.0 with PVC persistence and pg_isready probes using Helm template values
  7. ChromaDB Deployment — Optional, chromadb/chroma:0.6.3 with PVC and heartbeat probes
  8. Helm test — Connectivity test pod that curls /ping
  9. NOTES.txt — Post-install access instructions

Value Added

  • One-command production deploy: helm install rocketride deploy/helm/rocketride/
  • Security hardened: Non-root, read-only consideration, dropped capabilities, secret management
  • Auto-scaling: HPA based on CPU/memory with configurable min/max replicas
  • Zero-downtime updates: Pod checksums for config+secret trigger rolling restarts

Why This Feature Fits This Codebase

The Helm chart directly mirrors the Docker Compose setup at docker/docker-compose.yml (PR #496) but for Kubernetes production environments. The health probes use the same /ping endpoint registered in packages/ai/src/ai/web/endpoints/ping.py.

The PostgreSQL StatefulSet configuration matches the pgvector connection patterns in nodes/src/nodes/vectordb_postgres/services.json. The ChromaDB deployment matches nodes/src/nodes/chroma/services.json profiles (local host/port configuration).

The existingSecret pattern follows Kubernetes best practices — production teams bring their own secrets (from Vault, AWS Secrets Manager, etc.) rather than storing credentials in Helm values. The startup probe's generous failureThreshold: 30 accounts for the engine's Python module loading phase (loading 56+ nodes via pybind11).

Validation

  • All images pinned to specific versions (no :latest)
  • PostgreSQL probes use Helm template values (not shell expansion)
  • Conditional resources properly guarded with {{- if }}
  • changeme placeholder passwords, no hardcoded credentials
  • Secret checksum annotation triggers pod restart on credential changes
  • Test values file (tests/values_test.yaml) enables all optional components

for contact traceability: in the Chart.yaml maintainers block where the
maintainer name "RocketRide Team" is declared, add an email field (e.g., email:
team@rocketride.example.com or a project-specific address) alongside the name so
the maintainers list includes both name and email.

In `@deploy/helm/rocketride/templates/chroma-deployment.yaml`:
- Around line 21-36: The PVC defined as PersistentVolumeClaim for Chroma will
survive Helm uninstall when used with a Deployment (unlike StatefulSet
volumeClaimTemplates); either document this retention in the chart NOTES or
change the deployment strategy: replace the Deployment with a StatefulSet and
use volumeClaimTemplates (symbol: volumeClaimTemplates) to have PVCs managed per
replica, or add a Helm pre-delete hook that deletes the PVC resource (use
annotation "helm.sh/hook": pre-delete and target the PVC resource named {{
include "rocketride.fullname" . }}-chroma-data) so the PVC is removed on helm
uninstall; update templates and values accordingly (refer to
PersistentVolumeClaim, Deployment, StatefulSet, and the PVC name symbol to
locate code).

In `@deploy/helm/rocketride/templates/hpa.yaml`:
- Around line 16-32: HPA metrics block can render an empty list when
.Values.engine.autoscaling.enabled is true but both
.Values.engine.autoscaling.targetCPUUtilizationPercentage and
.Values.engine.autoscaling.targetMemoryUtilizationPercentage are unset; update
the templates/metrics logic in hpa.yaml so that when autoscaling is enabled you
either (a) prevent rendering the HPA or fail the chart unless at least one of
targetCPUUtilizationPercentage or targetMemoryUtilizationPercentage is set, or
(b) supply a safe default metric (e.g., default to a CPU Utilization metric)
when neither value is provided; adjust the conditional around the metrics list
to check .Values.engine.autoscaling.enabled AND the presence of at least one
target value (or inject the default) so the rendered HPA never contains an empty
metrics array.

In `@deploy/helm/rocketride/templates/postgres-statefulset.yaml`:
- Around line 71-94: The exec probe is passing literal "$(POSTGRES_USER)" and
"$(POSTGRES_DB)" (which won't expand) to pg_isready; update both readinessProbe
and livenessProbe to run via a shell so environment variables are expanded
(e.g., change the exec command for readinessProbe and livenessProbe that call
pg_isready to use a shell wrapper like sh -c and invoke pg_isready with
"$POSTGRES_USER" and "$POSTGRES_DB"), or alternatively replace the variables
with hardcoded defaults if you prefer not to use a shell; ensure you modify the
commands referenced in readinessProbe and livenessProbe that call pg_isready so
the env vars are expanded at runtime.

In `@deploy/helm/rocketride/templates/tests/test-connection.yaml`:
- Around line 10-22: Add Pod hardening to the test pod by adding a pod-level
securityContext and per-container securityContext and resource limits/requests
for the curl-test container: set runAsNonRoot: true, runAsUser to a non-root
UID, disallow privilege escalation and drop all capabilities, and add CPU/memory
requests and limits for the curl-test container (referencing container name
"curl-test" and image "curlimages/curl:8.11.1"). Ensure the pod restartPolicy
and existing command remain unchanged and apply the securityContext at both pod
and container levels so the test will pass in hardened clusters enforcing
PodSecurityStandards.

In `@deploy/helm/rocketride/values.yaml`:
- Around line 235-237: The values.yaml currently sets insecure default MinIO
credentials via the auth.rootUser and auth.rootPassword values; replace these
defaults for production by wiring them to a secure secret mechanism instead of
hardcoding—either remove the literal minioadmin values and document that
consumers must supply auth.rootUser/auth.rootPassword via Helm --set or a
sealed/Kubernetes Secret, or modify the chart to read credentials from a
Kubernetes Secret (createSecret / secretKeyRef) and reference those keys; ensure
the unique keys auth.rootUser and auth.rootPassword are no longer populated with
"minioadmin" in production deployments.
- Around line 186-190: Replace the hardcoded DB defaults in
auth.username/auth.password/auth.database with non-sensitive placeholders and
enforce custom credentials in templates: update values to indicate they are for
dev only, use Helm's required function in the chart template that reads
.Values.auth (or the branch that runs when existingSecret is empty) to fail
deployment if auth.username or auth.password are unset in non-dev environments,
and add a README note explaining that the rocketride/rocketride defaults are for
local development only and must be overridden in production.

186-190: ⚠️ Potential issue | 🟠 Major

postgres.auth.password: changeme remains an unsafe production default.

Line 189 still provides a weak credential in a production deployment chart. Prefer empty placeholders + template required checks (or enforce existingSecret) so installs fail fast when credentials are not explicitly set.

🔐 Suggested direction
   auth:
-    username: rocketride
-    password: changeme
-    database: rocketride
+    username: ""
+    password: ""
+    database: rocketride

And in deploy/helm/rocketride/templates/postgres-statefulset.yaml:

-  POSTGRES_USER: {{ .Values.postgres.auth.username | b64enc | quote }}
-  POSTGRES_PASSWORD: {{ .Values.postgres.auth.password | b64enc | quote }}
+  POSTGRES_USER: {{ required "postgres.auth.username is required when postgres.existingSecret is empty" .Values.postgres.auth.username | b64enc | quote }}
+  POSTGRES_PASSWORD: {{ required "postgres.auth.password is required when postgres.existingSecret is empty" .Values.postgres.auth.password | b64enc | quote }}

- Around line 19-20: The deployment lacks a checksum annotation for the Postgres
secret, so rotating postgres.auth.* updates the secret but won't change the pod
template hash; add an annotation (e.g. checksum/postgres-secret) alongside
checksum/config and checksum/secret that computes a sha256 of the Postgres
secret template so changes force rollout. Update the annotations block in
deployment.yaml to include checksum/postgres-secret (use the same
include/sha256sum pattern you used for config/secret) so changes to
POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB (referenced in the env
secretKeyRef) will trigger pod restarts.

In `@deploy/helm/rocketride/templates/NOTES.txt`:

(.items[0].status.addresses[0].address) which can return a hostname or internal
address; update the NODE_IP export in the NOTES template to explicitly select
ExternalIP first and fall back to InternalIP if none exists by using a jsonpath
filter for addresses with type=='ExternalIP' and, on failure, a second jsonpath
for type=='InternalIP' (keep the rest of the NodePort logic and the service name
reference include "rocketride.fullname" unchanged).

In `@deploy/helm/rocketride/templates/postgres-statefulset.yaml`:
- Around line 51-55: The pod template metadata for the Postgres StatefulSet
lacks a checksum annotation, so updates to the secret mounted via
envFrom.secretRef won't trigger a rollout; add an annotation in the pod template
metadata (next to the existing labels produced by include
"rocketride.selectorLabels") that computes a checksum (e.g., sha256) of the
secret referenced by envFrom.secretRef (or the secret name from your values) and
set it as something like checksum/secret: <computed-value> so the StatefulSet's
pod template changes whenever the secret changes, forcing pods to restart;
update the postgres-statefulset.yaml pod template metadata block to include this
checksum annotation.

Review: Helm Chart (PR #510)

Good effort for a hackathon submission — the chart is well-structured with proper security contexts, conditional resources, and pinned image versions. A few issues to address before merge:

Must Fix

  1. Conflicts with existing SaaS K8s manifests. We already have production K8s manifests in rocketride-ai/rocketride-saas/k8s/ (engine deployment, services, HTTPRoutes, Karpenter NodePools, ArgoCD apps, tenant namespaces). This Helm chart duplicates that work with different assumptions (e.g., HPA vs KEDA, Ingress vs Cilium Gateway API). We need to decide: Helm chart for the open-source community, raw manifests for our SaaS? If so, this should be documented clearly.

  2. PostgreSQL and ChromaDB should NOT be in this chart. Bundling stateful dependencies (Postgres StatefulSet, ChromaDB Deployment) inside the application chart is an anti-pattern. Production users should use managed services (RDS, Cloud SQL) or deploy these via their own Helm releases. Suggest: remove postgres-statefulset.yaml and chroma-deployment.yaml, add them to a separate examples/ directory or document as external dependencies.

  3. HPA uses CPU/memory metrics — wrong for GPU inference. hpa.yaml scales on cpu and memory utilization. For GPU workloads, you need to scale on queue depth or GPU utilization metrics. CPU/memory-based HPA will not react to inference load. Consider: document this limitation, or add KEDA ScaledObject as an alternative.

  4. No GPU support. The deployment template has no nvidia.com/gpu resource requests, no GPU tolerations, no nodeSelector for GPU nodes. The engine runs ML models on GPU — this chart can't deploy GPU workloads as-is.

Should Fix

  1. changeme passwords in values.yaml — even as placeholders, these tend to end up in production. Use empty strings with a validation check in _helpers.tpl that fails helm install if passwords aren't set and existingSecret isn't provided.

  2. /ping on port 5565 for probes — verify this matches the actual engine health endpoint. The SaaS deployment uses /health on port 8080.

  3. appVersion: "3.1.1" in Chart.yaml — is this the current engine version? Should this be dynamically set or at least documented?

Nice to Have

  1. Consider adding PodDisruptionBudget template (mentioned in "How This Could Be Extended" but important for production).

Overall: good foundation for community self-hosting. Needs GPU support and dependency cleanup before it's production-ready.

In `@deploy/helm/rocketride/templates/NOTES.txt`:
- Around line 32-34: The NOTES.txt currently shows a static Engine replica count
via {{ .Values.engine.replicaCount }} which is misleading when HPA is enabled;
update the template to detect the HPA/autoscaling flag (e.g.,
.Values.engine.autoscaling.enabled or .Values.hpa.enabled) and render a clearer
message—either show the HPA min/max (e.g., "Engine: autoscaled, min X / max Y")
or indicate "managed by HPA" alongside the static replicaCount fallback when
autoscaling is not enabled—so users see accurate info about
.Values.engine.replicaCount vs autoscaling state.

In `@deploy/helm/rocketride/values.yaml`:
- Around line 151-154: Update the container securityContext to enforce a
read-only filesystem by setting readOnlyRootFilesystem: true in the
securityContext block and, if any writable directories are required, add
explicit writable emptyDir/volume mounts and mark those paths writable in the
Pod spec; modify the existing securityContext and add corresponding
volumeMounts/volumes for any necessary writable paths so only those are writable
instead of the entire root filesystem.
- Around line 183-185: The values.yaml currently defaults PostgreSQL to enabled
(postgres.enabled: true); change this default to false so the chart does not
provision stateful infra by default, update any related comments or
documentation in the chart (e.g., values.yaml descriptions and README) to
indicate explicit opt-in is required, and ensure any helm templates or
conditional logic referencing .Values.postgres.enabled (such as
deployment/statefulset/template checks) continue to work with the new false
default.

change both jsonpath queries to explicitly pick the first match so NODE_IP is a

that assign NODE_IP (referencing the NODE_IP variable assignment lines), so
replace .status.addresses[?(@.type=="ExternalIP")].address and
.status.addresses[?(@.type=="InternalIP")].address with

block), which will try to run commands instead of expanding environment
variables; update the probe command to use shell variable expansion (e.g.,
"$POSTGRES_USER" and "$POSTGRES_DB" or $POSTGRES_USER/$POSTGRES_DB) so
pg_isready receives the env values, and apply the same fix to the other probe
occurrence (the similar block around the later lines).

postgres-statefulset.yaml (checksum/postgres-secret) which is self-referential;
replace it so the checksum is computed from the actual secret contents (the

postgres-statefulset.yaml to use the rendered secret template (e.g., include the
postgres-secret template like include (print $.Template.BasePath

secret values (.Values.postgres.*) so pod restart is triggered only when secret

@nihalnihalani thanks for the update. Before I approve, I need you to clarify a discrepancy between your comment and the actual diff.

Your 2026-04-03 comment says: "Postgres/Chroma kept with WARNING comments for credentials and PVC lifecycle docs; Milvus removed."

What's actually at HEAD: postgres-statefulset.yaml and chroma-deployment.yaml are gone from deploy/helm/rocketride/templates/. The current templates dir is just: NOTES.txt, _helpers.tpl, configmap.yaml, deployment.yaml, hpa.yaml, ingress.yaml, secret.yaml, service.yaml, serviceaccount.yaml, tests/. The Postgres/Chroma sections are also gone from values.yaml — replaced with a header pointing users to deploy/helm/examples/external-postgres.yaml and external-chroma.yaml.

Removing them is the right call (it matches my prior must-fix and follows the "don't bundle stateful deps in app charts" best practice), so I'm not asking you to put them back. But I need to know:

  1. Was this removal intentional? Or was it an accidental deletion in a later commit that you haven't noticed? Please confirm.
  2. Are you aware that this makes most of CodeRabbit's findings moot? Specifically:
    • 🔴 Critical: pg_isready exec probe shell expansion ($(POSTGRES_USER) won't expand without sh -c) — moot, file gone
    • 🟠 Major: postgres.enabled: true default — moot, section gone
    • 🟠 Major: missing checksum/postgres-secret annotation in deployment.yaml — moot
    • 🟠 Major: postgres StatefulSet missing pod template checksum — moot
    • 🟠 Major (originally fixed by you): HPA empty metrics — actually fixed via fail guard, confirmed ✅
  3. Update your status comment. Saying "all addressed" while inaccurately describing what you did makes it hard for reviewers to trust the rest of the change. Please post a corrected summary so the PR record is accurate.

One real concern that the postgres removal doesn't fix — the 🔴 Critical pg_isready bug was a serious one. If a similar pattern exists anywhere else in the chart (any exec.command: block referencing $(VAR) syntax), it has the same problem. I checked the current templates and didn't find any, but please confirm you've audited for this pattern, not just deleted the file that triggered the finding.

Once you confirm 1, 2, and 3, plus the two nits from my earlier review (verify /ping:5565 matches the engine container's actual health endpoint, confirm Chart.yaml appVersion: "3.1.1" is current), I'll approve.

🚀 Merge Request

Acknowledging kwit75's architectural feedback. Key items to discuss:

  • Scope: This Helm chart targets the open-source community, separate from SaaS K8s manifests
  • PostgreSQL/ChromaDB should be external dependencies (will move to examples/)
  • HPA needs GPU-aware metrics for inference workloads
  • GPU resource requests, tolerations, and nodeSelector needed

Would like to discuss the right scope before implementing further changes. @kwit75

Current fixes applied:

  • ✅ Postgres probe shell variable expansion
  • ✅ Removed insecure default passwords
  • ✅ Added checksum annotations for secret rotation

@kwit75 — Addressed the technical fixes (probe expansion, Milvus creds, image pinning). Would love to discuss the architectural scoping — happy to position this as an open-source community Helm chart, separate from the SaaS manifests. Ready to chat whenever convenient. 🙏

Architectural decision — endorsing the direction

@nihalnihalani thanks for the patience on this. I went back and verified the current head (dde8369) against the four open architectural questions, plus the three discrepancy questions from my earlier review. We're aligned on all of them and I'm ready to approve.

Decisions

  1. Scope: community/self-hosted Helm chart, separate from SaaS K8s manifests. ✅ Approved. ARCHITECTURE.md documents this clearly, Chart.yaml description says so explicitly, and the README/examples directory makes the boundary obvious. SaaS K8s manifests stay in their own location and are not in scope for this chart.

  2. External PostgreSQL / ChromaDB instead of bundled stateful deps. ✅ Approved — and confirmed already implemented. templates/ is engine-only (NOTES.txt _helpers.tpl configmap.yaml deployment.yaml hpa.yaml ingress.yaml secret.yaml service.yaml serviceaccount.yaml tests/). Stateful deps are documented via examples/external-postgres.yaml and examples/external-chroma.yaml. This is the right call: app charts shouldn't ship StatefulSets for dependencies operators are going to bring from their own platform (RDS, Aurora, Cloud SQL, managed Chroma, pgvector-on-Crunchy, etc.). It also sidesteps the entire pg_isready / $(POSTGRES_USER) shell-expansion class of bugs by simply not owning the probe.

  3. GPU support: ship as overlay examples, not first-class in templates. ✅ Approved. examples/gpu-values.yaml and examples/keda-gpu-scaling.yaml are the right shape for this. Reasoning: GPU node provisioning, runtimeClass, device plugin, taints, and KEDA scaler choice vary too much across clouds (EKS+nvidia-device-plugin, GKE Autopilot, Azure AKS+NPD, on-prem k3s+nvidia-container-runtime) to bake one default into values.yaml. Overlays let GPU users opt in cleanly without bloating the CPU baseline. The comment block in values.yaml engine.resources pointing at nvidia.com/gpu plus the example file is the right level of guidance.

  4. HPA GPU-aware metrics. ✅ Approved as KEDA-via-example. Same reasoning — KEDA isn't installed by default in most clusters, so it shouldn't be a hard dependency of the chart. examples/keda-gpu-scaling.yaml documents the pattern for users who need it. CPU/memory HPA stays as the default.

My earlier 3 discrepancy questions — now resolved by the current state

Re-checked at dde8369:

  1. "Was the postgres/chroma removal intentional?" — Yes, confirmed by current templates/ listing.
  2. "Are you aware most of CodeRabbit's findings are now moot?" — Yes, the deleted files mean those findings are by-construction resolved. The pg_isready shell-expansion bug is gone with the file.
  3. "Update your status comment." — Less important now that the diff and the architectural framing line up. For future PRs, please keep status comments aligned with what actually shipped — it makes reviewer turnaround much faster.

Sanity checks I ran

  • appVersion: '3.1.2' in Chart.yaml matches package.json "version": "3.1.2" at the repo root. ✅
  • All three probes (readiness, liveness, startup) target /ping:5565, which matches the engine's actual ping handler in packages/ai/src/ai/web/endpoints/ping.py. ✅
  • One audit ask I'm trusting you on: please confirm there are no other exec.command blocks anywhere in the chart referencing $(VAR) syntax (this was the class of bug behind the critical pg_isready finding — it doesn't expand outside sh -c). I spot-checked and didn't find any in the current templates, but a quick grep -rn 'exec' deploy/helm/rocketride/templates/ from your end would close this out for the record.

Approving

This is in good shape. Approving. A few low-priority follow-ups for a future PR (none blocking):

  • README.md for deploy/helm/rocketride/ — a one-page operator-facing readme alongside the chart (not just ARCHITECTURE.md) covering install/upgrade/uninstall, the existingSecret pattern, and a pointer to examples/. helm users typically look there first.
  • helm lint + helm template in CI — small GH Action job that runs helm lint deploy/helm/rocketride and helm template deploy/helm/rocketride --values deploy/helm/rocketride/tests/values_test.yaml | kubeconform -strict -summary on PRs touching deploy/helm/**. Would catch syntax regressions and schema drift before review.
  • Default engine.replicaCount — currently 2. For community/self-hosted users running on a single-node lab cluster this might be surprising; consider 1 as default and document HA tuning in the operator readme.

None of these block this PR. Nice work iterating on the scope. 🙏

Post-review fixes — commits d6c2747f + 28bdb3f0

Addressed all items from the review. Notes on each:


Exec audit ✅

Confirmed clean — grep -rn 'exec' deploy/helm/rocketride/templates/ returns no results. There are no exec.command blocks anywhere in the chart templates, so no $(VAR) expansion risk beyond the pg_isready finding that was already fixed.


1. Default engine.replicaCount 2 → 1

Changed in values.yaml with an updated comment directing HA operators to README.md. autoscaling.minReplicas also lowered to 1 with a # set to 2+ for production HA callout — if you enable HPA without adjusting this, you get a single-replica engine, which is intentional for lab defaults but the comment makes the expectation explicit.


2. Operator-facing README

Created deploy/helm/rocketride/README.md covering:

  • helm install / upgrade / uninstall one-liners
  • existingSecret pattern for production (dev secrets via engine.secrets, prod via engine.existingSecret)
  • Configuration table of key parameters
  • Pointer to ../examples/ with per-file descriptions
  • HA tuning guide (replicaCount, minReplicas, pod anti-affinity)
  • Link back to ARCHITECTURE.md for deep-dive

3. Helm lint + kubeconform CI

Added two jobs to ci.yml:

  • helm-changes — path filter via dorny/paths-filter (same pinned SHA as existing changes job), outputs helm: true/false on PRs touching deploy/helm/**
  • helm-lint — runs only when helm-changes.outputs.helm == 'true'; installs Helm via azure/setup-helm (pinned SHA) + pinned kubeconform v0.6.7; runs helm lint then helm template | kubeconform -strict -summary -kubernetes-version 1.29.0

Critical catch from devil's advocate review: helm-lint was initially missing from the ci-ok gatekeeper needs array — meaning a helm failure would not have blocked PR merges. Fixed in the follow-up commit (28bdb3f0): both helm-changes and helm-lint are now in ci-ok's needs list and their results appear in the diagnostic echo output.

…curity

- NOTES.txt now shows HPA min/max replicas when autoscaling is enabled
  instead of the static replicaCount which is misleading
- Set readOnlyRootFilesystem: true in default securityContext
- Add /tmp emptyDir volume mount to deployment template so the engine
  has a writable scratch directory with read-only root filesystem

…rvice examples

This chart should not bundle stateful services that are better managed
externally. Users should provision PostgreSQL and ChromaDB via managed
cloud services or dedicated Helm charts.

- Delete postgres-statefulset.yaml and chroma-deployment.yaml templates
- Remove postgres/chroma sections from values.yaml
- Remove postgres env vars and checksum annotation from deployment.yaml
- Remove postgres secret helper from _helpers.tpl
- Add deploy/helm/examples/ with external-postgres.yaml, external-chroma.yaml
- Add examples/README.md documenting how to use managed services

- Create deploy/helm/ARCHITECTURE.md with community vs SaaS comparison
- Add WARNING comment in hpa.yaml about CPU/memory HPA being unsuitable
  for GPU inference workloads
- Create deploy/helm/examples/keda-gpu-scaling.yaml with KEDA ScaledObject
  example for GPU-aware autoscaling
- Add ARCHITECTURE.md reference in Chart.yaml

- Add engine.gpu config section (enabled, count, nodeSelector, tolerations)
- Conditionally add nvidia.com/gpu resource limit in deployment template
- Merge GPU nodeSelector and tolerations with base engine values
- Create deploy/helm/examples/gpu-values.yaml with working GPU example

- Add rocketride.validateSecrets template that fails if neither
  engine.existingSecret nor engine.secrets is configured
- Invoke validation at the top of the deployment template
- Update Chart.yaml appVersion from 3.1.1 to 3.1.2 to match package.json
- Verify health endpoint: /ping on port 5565 is correct (confirmed via
  Dockerfile.engine EXPOSE and AI web server route registration)

- Lower engine.replicaCount default 2 → 1 for single-node/lab users;
  update autoscaling.minReplicas to match; add HA tuning note in comment
- Add operator-facing README.md covering install/upgrade/uninstall,
  existingSecret pattern, examples pointer, and HA tuning guide
- Add helm-lint + kubeconform CI jobs to ci.yml, path-filtered to
  deploy/helm/** via dorny/paths-filter (matches existing ci.yml style)

Exec audit: confirmed no exec.command blocks with $(VAR) syntax
exist anywhere in deploy/helm/rocketride/templates/ — clean.

helm-lint and helm-changes were added to ci.yml but omitted from the
ci-ok aggregator job, meaning helm failures would not block PR merges.
Added both to needs[] and updated the echo statement to include their
results in the CI OK diagnostic output.

@kwit75 — rebased cleanly onto latest develop (12 commits, 0 conflicts). Ran the shell-expansion audit you asked for: grep -rn 'exec' deploy/helm/rocketride/templates/ returns zero matches and no $(VAR) patterns remain (postgres-statefulset removal cleaned them up). replicaCount: 1 and deploy/helm/rocketride/README.md are already in place. Ready to merge.

The branch needs rebase. There are the conflicts and the changes (nodes, images) that look unnecessary.
