In `@deploy/helm/templates/persistentVolume.yaml`:
- Around line 42-45: The PersistentVolume manifest includes a metadata.namespace
field which is invalid because PVs are cluster-scoped; remove the namespace
entry from the persistentVolume.yaml metadata block (the block containing name:
{{ include "appsmith.pvName" . }} and labels:) so the template no longer renders
a namespace for the PV; if conditional behavior is desired, ensure any
templating around metadata.namespace is removed or gated so no namespace key is
emitted for the PV resource.
- Around line 11-39: Add a validation block that counts enabled persistence
backends and fails when the count is not exactly one: evaluate
.Values.persistence.localStorage, .Values.persistence.efs.enabled,
.Values.persistence.nfs.enabled, .Values.persistence.ebs.enabled and
.Values.persistence.gcp.enabled (coerce each to 0/1), sum them, and call fail
with a clear message if the sum != 1 so the chart ensures exactly one backend is
selected (use the same fail mechanism as existing checks and reference these
symbols in the new validation).
In `@deploy/helm/templates/service.yaml`:
- Around line 39-43: The Service template currently hardcodes sessionAffinity:
ClientIP and sessionAffinityConfig.clientIP.timeoutSeconds, which prevents
operators from disabling or tuning it; make this driven by Helm values (e.g.,
.Values.service.sessionAffinity and
.Values.service.sessionAffinityConfig.clientIP.timeoutSeconds) and guard the
sessionAffinityConfig block with a conditional so it is only rendered when
sessionAffinity is set to "ClientIP" (and/or when timeoutSeconds is provided),
ensuring defaults remain nil/unset unless the chart values explicitly enable or
override them.
In `@deploy/helm/templates/serviceaccount.yaml`:
- Around line 28-30: The ServiceAccount's secrets block unconditionally
references the Secret rendered only when .Values.secrets is set; update the
ServiceAccount template (the secrets: - name: {{ template "appsmith.fullname" .
}} entry) to be conditionally rendered only when .Values.secrets is truthy
(i.e., wrap the entire secrets stanza in a Helm conditional checking
.Values.secrets) so the ServiceAccount does not point to a non-existent Secret.
- Around line 17-19: Remove the annotations
rbac.authorization.k8s.io/aggregate-to-edit and
rbac.authorization.k8s.io/aggregate-to-view from the ServiceAccount manifest
(the ServiceAccount resource block) and add them to the ClusterRole resource
that should aggregate permissions (the ClusterRole manifest / resource for your
app), ensuring the same annotation keys and values are present on the
ClusterRole so RBAC aggregation will be honored.
In `@HELM_IMPROVEMENTS.md`:
- Around line 220-236: The fenced commit-history block under the "## 📝 Commit

the triple-backtick block (the ``` that begins the commits list) to include a
language tag such as ```text (or ```git) so the block is labeled and

Does Kubernetes PersistentVolumeSpecrequire exactly one volume source field (for examplecsi, nfs, local, or awsElasticBlockStore) to be set?
💡 Result:
Yes, Kubernetes PersistentVolumeSpec requires exactly one volume source field (such as csi, nfs, local, or awsElasticBlockStore) to be set. The API schema defines multiple mutually exclusive optional fields for different volume types, but validation enforces that exactly one must be specified. Attempting to create a PV without any volume source results in the error: "The PersistentVolume is invalid: spec: Required value: must specify a volume type". Setting multiple sources would also be invalid due to semantic constraints enforced by the API server validation.

Add validation ensuring exactly one persistence backend is enabled.
The template validates individual backend fields but never ensures one—and only one—of localStorage, efs.enabled, nfs.enabled, ebs.enabled, or gcp.enabled is active. With defaults (localStorage: false and other backends unset), the rendered PersistentVolume has no volume source field, causing Kubernetes to reject it with: "spec: Required value: must specify a volume type". Enabling multiple backends simultaneously also violates Kubernetes constraints.

🌐 Web query:
Are Kubernetes PersistentVolumeresources cluster-scoped, and shouldmetadata.namespace be omitted from their manifests?
💡 Result:
Yes, Kubernetes PersistentVolume (PV) resources are cluster-scoped, meaning they are not namespaced and can be accessed from any namespace in the cluster. The metadata.namespace field should be omitted from their manifests, as including it will cause the API server to reject the creation (PV is a non-namespaced resource).

Remove metadata.namespace from PersistentVolume.
PersistentVolumes are cluster-scoped resources, and the API server rejects manifests that include a namespace field. This will prevent the PV from being created.

Make session affinity configurable instead of always-on.
deploy/helm/values.yaml:185-229 does not expose any session-affinity settings, so this changes the Service’s default traffic behavior for every install and gives operators no way to disable or tune it without patching the template.

In Kubernetes RBAC, do the rbac.authorization.k8s.io/aggregate-to-editandrbac.authorization.k8s.io/aggregate-to-viewannotations have any effect onServiceAccountresources, or are they only honored onClusterRole objects?
💡 Result:
The rbac.authorization.k8s.io/aggregate-to-edit and rbac.authorization.k8s.io/aggregate-to-view annotations (actually labels) have no effect on ServiceAccount resources. They are only honored on ClusterRole objects. These labels are used on ClusterRole objects to indicate that their rules should be automatically aggregated into Kubernetes' built-in ClusterRoles like edit, view, and admin. A controller watches for ClusterRoles with these specific labels and merges their rules into the target aggregating ClusterRole (which has an aggregationRule field selecting for these labels). ServiceAccount is a different API resource in the v1 core group, used for identities in Pods. It has no aggregationRule field and is not part of the RBAC aggregation mechanism. No sources mention these labels applying to ServiceAccounts; all examples and documentation show them exclusively on ClusterRoles.
