## What this PR does Re-vendors the `linstor-scheduler` chart from upstream **0.3.1** (appVersion **v0.3.6**). Upstream now ships the admission webhook natively (contributed via [piraeusdatastore/helm-charts#94](https://github.com/piraeusdatastore/helm-charts/pull/94)), so the loose downstream admission templates — which round-tripped every Pod through an old `k8s.io/api` and silently stripped fields they did not know about, the `image` volume source and the native-sidecar `restartPolicy` among them, breaking KubeVirt containerDisk VMs and native sidecars cluster-wide — are dropped in favour of the upstream copy. - The admission webhook comes from the upstream chart now; the previous downstream copy and its patch are removed. `make update` pulls 0.3.1 and applies only `cozystack-scheduler-deployment.patch` (the scheduler pod component label and the distro-suffix-stripped kube-scheduler image tag, neither of which is upstream yet), so vendoring stays deterministic and reproducible. - The upstream admission Deployment keeps the same name but changes its immutable pod selector, so an in-place upgrade of an existing install would fail with `field is immutable`. Migration 52 deletes the old admission Deployment before the upgrade so the new one is recreated cleanly (`targetVersion` 52 → 53). - appVersion v0.3.6 also carries the webhook's TLS certificate hot-reload fix ([piraeusdatastore/linstor-scheduler-extender#22](https://github.com/piraeusdatastore/linstor-scheduler-extender/pull/22)): the webhook used to load its certificate once at startup, so after the mounted Secret was rotated it kept serving a stale certificate and — with `failurePolicy: Ignore` — silently stopped mutating until it was restarted. It now reloads on rotation, so no external cert-reload workaround is needed here. - Wrapper values keep `replicaCount: 2`, now that the admission Pods have their own PodDisruptionBudget and no longer share the scheduler's. - Adds a helm-unittest suite covering the admission resources, PodDisruptionBudget selector isolation, least-privilege RBAC, the TLS provisioning modes and their rejection paths, the scheduler image-tag strip, and backward compatibility with the webhook disabled. Closes #3198. ### Screenshots N/A — no UI changes. ### Downstream repositories I walked the trigger map against the diff, file by file. It touches `packages/system/linstor-scheduler/` and, under `packages/core/platform/`, only migration 52 and the `migrations.targetVersion` bump — an internal, release-managed counter, not a user-facing `spec.components.platform.values.*` key documented on the website. No trigger matches. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: ### Release note ```release-note fix(linstor-scheduler): the LINSTOR scheduler admission webhook no longer strips unknown Pod fields (the `image` volume source and native-sidecar `restartPolicy`), which had broken KubeVirt containerDisk VMs and native sidecars, and it now reloads its TLS certificate after rotation instead of silently failing. The chart is re-vendored from upstream 0.3.1; an automatic upgrade migration replaces the admission Deployment whose immutable selector changed. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Expanded the optional Linstor Scheduler admission webhook with richer configuration, including automated `schedulerName` mutation for LINSTOR CSI-backed PVC Pods. * **Improvements** * Updated the Linstor Scheduler Helm chart to **0.3.1** (scheduler app **v0.3.6**), including updated admission webhook behavior, safer defaults, and **2 replicas**. * Platform migrations now advance to **version 53**, with upgrade-safe cleanup of the existing admission deployment. * **Documentation** * Updated Helm README and post-install notes with detailed guidance for admission webhook and TLS modes. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
