Closes#22250
## What
Adds four standard pod spec fields to both server and worker Deployments
of the Helm chart, exposed under `server.*` and `worker.*` in
`values.yaml`:
- `nodeSelector`
- `tolerations`
- `dnsPolicy`
- `dnsConfig`
## Why
Self-hosters who run Twenty on clusters with dedicated nodes, taints, or
custom DNS requirements currently need to fork the chart or patch
rendered manifests with Kustomize. These are the standard pod spec
fields supported by virtually every other community chart (Bitnami,
prometheus-community, cert-manager, etc.) and are commonly needed in
production setups.
## How
Uses the same `{{- with }}` pattern already present in the chart (e.g.
`extraEnv`, `extraVolumeMounts`), so empty defaults skip rendering
entirely:
```yaml
{{- with .Values.server.nodeSelector }}
nodeSelector:
{{- toYaml . | nindent 8 }}
{{- end }}
```
## Backward compatibility
Fully backward compatible. Defaults are empty:
```yaml
server:
nodeSelector: {}
tolerations: []
dnsPolicy: ~
dnsConfig: {}
```
`helm template` output is bit-identical to the previous version for any
existing install.
## Schema note
`dnsPolicy` is typed as `[string, null]` and the enum includes `null` so
the empty default (`dnsPolicy: ~`) passes validation. The `{{- with }}`
guard treats null as falsy and renders nothing.
## Validation
- `helm lint` passes
- `helm template` with default values produces bit-identical output to
before this PR
- `helm template` with values set renders the four fields correctly on
both server and worker
- Live install validated on a multi-node Kubernetes cluster, pinning
Twenty to a dedicated tainted node with custom DNS (`ndots: 1`); server
and worker scheduled and started successfully
