## What this PR does Exposes standard Helm `resources` values for the three core workloads in the `cozystack-engine` package, and makes `cozystack-controller` replicas configurable (was hardcoded to `1`). **Changes by component:** | Component | `resources` | `replicas` | |---|---|---| | `cozystack-api` | ✅ NEW (`cozystackAPI.resources`) | already configurable | | `cozystack-controller` | ✅ NEW (`cozystackController.resources`) | ✅ NEW (`cozystackController.replicas`, default `1`) | | `lineage-controller-webhook` | ✅ NEW (`lineageControllerWebhook.resources`) | already configurable | Each template uses `{{- with .Values.xxx.resources }}` so the `resources:` block is only rendered when values are provided. Default `resources: {}` produces no output, so resource requests/limits stay opt-in. **Leader election:** `cozystack-controller` now always runs with leader election — the chart passes `--leader-elect` unconditionally and ships a namespaced `Role`/`RoleBinding` for the Lease in `cozy-system` (where controller-runtime creates it). Raising `cozystackController.replicas` therefore adds standbys instead of a second active writer over the reconcilers that patch HelmReleases, Gateways, Certificates, ResourceQuotas and Secrets; this holds whatever `replicas` is. A restart can pause reconciliation for up to the Lease duration (15s by default), because `LeaderElectionReleaseOnCancel` is off. With `replicas: 1` the change for an existing install is the flag plus the two RBAC objects. **Why:** Without these values, operators cannot set QoS guarantees and must resort to `kubectl patch`, Flux Kustomize SSA patches, or Kyverno mutations — all fragile under Helm upgrades. Closes #2955 ### Release note ```release-note feat(api): add configurable `resources` (requests/limits) for cozystack-api, cozystack-controller, and lineage-controller-webhook. `cozystack-controller` replicas is now configurable via `cozystackController.replicas` (default: 1). The `cozystack-controller` Deployment now always runs with leader election and creates a Lease in `cozy-system`, so raising `replicas` adds standbys rather than a second active controller; a restart can pause reconciliation for up to the Lease duration (15s by default). An empty `resources: {}` renders no resources block, so requests and limits remain opt-in. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Container resource requests and limits can now be configured for the API, controller, and webhook services; defaults remain unchanged. * The controller replica count is configurable, and leader election is enabled for multi-replica operation. * Controller leader-election access is limited to the `cozy-system` namespace. * **Documentation** * Documented the webhook resource configuration option. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
