Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to This adds opt-in PodDisruptionBudget configuration while keeping existing deployments unchanged by default. The committed value-wiring test addresses the prior coverage concern, so no actionable merge-blocking risk remains beyond normal checks. Sequence Diagram(s)sequenceDiagram

Add configurable PodDisruptionBudget support to all Helm charts in the self-managed stack. Each chart gains a podDisruptionBudget values block (enabled: false by default) that operators can activate in their environment file to protect against simultaneous voluntary evictions during node drains, cluster upgrades, and autoscaler events. Infrastructure (cassandra, nats, openbao): - cassandra: new PDB template + values; wired in global.yaml.gotmpl - nats: expose upstream chart podDisruptionBudget in wrapper values - openbao: expose server.ha.disruptionBudget; make injector PDB configurable Control-plane services (13 charts): - Add podDisruptionBudget.enabled/minAvailable/maxUnavailable to values.yaml - Add poddisruptionbudget.yaml template gated on enabled flag - Affected: ess, grpc-proxy, http-invocation, ratelimiter, llm-api-gateway, llm-request-router, admin-token-issuer-proxy, api-keys-colocated, nvca-operator, nats-auth-callout, function-autoscaler, helm-reval, container-cache (values only) Stack wiring: - global.yaml.gotmpl: passthrough for cassandra, nats, openbao PDB values Docs: - Add docs/user/pod-disruption-budgets.md with configuration reference - Link from optional-enhancements.md and fern nav
- Replace truthiness checks with toString comparison so minAvailable/ maxUnavailable: 0 renders correctly; add fail validation requiring exactly one of minAvailable or maxUnavailable when enabled (all 13 custom chart templates) - Add ess and rateLimiter podDisruptionBudget passthroughs to global.yaml.gotmpl (was missing after cassandra/nats/openbao) - Remove Markdown bold emphasis from pod-disruption-budgets.md per coding guidelines; fix accuracy of default-state description (NATS and OpenBao upstream charts enable PDB by default); add link to Kubernetes PDB documentation; update last-line wording to reflect fail-at-render behaviour
Add commented-out podDisruptionBudget blocks to base.yaml covering all charts that gained PDB template support: cassandra, nats, openbao (injector + server HA), rateLimiter, apikeys, ess, invocation, grpcproxy, adminIssuerProxy, functionautoscaler, reval, llmApiGateway, and llmRequestRouter. Also complete global.yaml.gotmpl PDB passthroughs for the seven control-plane services that were missing them (apikeys, invocation, grpcproxy, adminIssuerProxy, functionautoscaler, reval, llmApiGateway, llmRequestRouter).

podDisruptionBudget example from the grouped block, while preserving the
service-local grpcproxy block and its settings.
In `@deploy/stacks/self-managed/global.yaml.gotmpl`:
- Around line 42-45: Add render-test coverage for the self-managed chart’s pod
disruption budget value wiring, including omitted maps, disabled PDBs,
minAvailable, maxUnavailable, NATS merge.spec, and OpenBao injector and HA
paths. Extend the existing self-managed test target and run the
repository-native target, documenting in the pull request if the tests are not
applicable.

- Remove grpcproxy from the grouped PDB comment block in base.yaml — duplicate top-level keys would cause the second to silently overwrite the first; keep the PDB knob in the existing grpcproxy: section only - Add tests/pdb-value-wiring.sh covering: default-off (cassandra), minAvailable passthrough (cassandra), maxUnavailable passthrough (cassandra), both-fields fail validation (cassandra), NATS disabled override, OpenBao HA disruptionBudget passthrough, OpenBao injector PDB passthrough, rateLimiter passthrough, ess passthrough - Wire pdb-value-wiring.sh into the self-managed Makefile test target

- Line 4: Add a test case in the PDB validation scenarios for enabled: true with
neither minAvailable nor maxUnavailable configured, and assert that Cassandra
template rendering rejects it. Keep the existing case covering both fields set
and ensure the script’s stated coverage matches both invalid configurations.

tests to each target podDisruptionBudget mapping instead of searching the entire
rendered YAML document. Update the Cassandra, rateLimiter, and ess checks to
verify podDisruptionBudget.enabled is true while retaining their existing

grep -q 'enabled: true' on the full rendered values file can pass if any other chart key is true. Scope cassandra, rateLimiter, and ess checks to the podDisruptionBudget: block using grep -A2, matching the existing NATS pattern in the same script.
Per review feedback, expose all podDisruptionBudget blocks as active YAML (enabled: false) rather than commented-out examples. Operators can enable a PDB by flipping the flag without needing to uncomment anything.
…alse knobs The base.yaml PDB blocks are now active YAML with enabled: false rather than commented-out examples. Update the guide to reflect this.

Summary
podDisruptionBudgetvalues block to every Helm chart in the self-managed stack (enabled: falseby default)poddisruptionbudget.yamltemplates for 13 custom charts; upstream chart passthrough fornatsandopenbaoglobal.yaml.gotmplso operators can set them in their environment filedocs/user/pod-disruption-budgets.mdwith configuration reference and copy-paste examples for all chart typesMotivation
Operators running NVCF self-managed on managed Kubernetes clusters (EKS, GKE, AKS) need PDBs to prevent voluntary evictions from taking down entire stateful tiers (Cassandra, NATS, OpenBao) during node drains and cluster upgrades. Without PDBs, a single node drain can evict all three Cassandra pods simultaneously, causing an outage.
