Adds the VM/CDI storage tier approved by the PM (RWX for live-migration): - platform/external-snapshotter (NEW, controllers pass): the cluster-singleton snapshot.storage.k8s.io control plane (CRDs + snapshot-controller in kube-system), pinned v8.2.0 (Kubernetes deps aligned to 1.31 since v8.1.0; this cluster is k3s v1.31.5). These CRDs were absent — only snapshots.longhorn.io and kubevirt.io snapshot CRDs existed. - platform/longhorn/volumesnapshotclass.yaml (NEW, platform-config): the driver.longhorn.io VolumeSnapshotClass (type: snap, in-cluster). - platform/kubevirt/cdi-storageprofiles.yaml (NEW, platform-config): StorageProfile longhorn -> cloneStrategy: snapshot; StorageProfile longhorn-vm -> snapshot clone + claimPropertySets RWX/Block. Non-degraded default virt class clears CDIDefaultStorageClassDegraded. - platform/longhorn/storageclasses.yaml: NEW longhorn-vm StorageClass — migratable: "true" (Longhorn's KubeVirt-live-migration knob; RWX/Block-only on 1.7.3), is-default-virt-class (NOT the k8s default; longhorn stays RWO default). - platform/kubevirt/kubevirt-cr.yaml: comment only — LiveMigration is GA on v1.9 (no feature gate); no cluster-wide evictionStrategy (would wedge RWO-disk drains); live-migration stays per-VM opt-in on a longhorn-vm disk.

# external-snapshotter — the cluster-wide CSI snapshot control plane (Phase 2, storage).
|
|
#
|
|
# WHY: Longhorn's CSI driver (driver.longhorn.io) can create CSI VolumeSnapshots, but the
|
|
# `snapshot.storage.k8s.io` API (VolumeSnapshot / VolumeSnapshotContent / VolumeSnapshotClass)
|
|
# and the snapshot-controller that reconciles them are NOT part of k3s or of Longhorn — they are
|
|
# a SEPARATE, cluster-singleton component (kubernetes-csi/external-snapshotter). Without it the
|
|
# CRDs are absent (only `snapshots.longhorn.io` + the kubevirt.io snapshot CRDs exist), so:
|
|
# * no VolumeSnapshotClass can be created (item 2), and
|
|
# * CDI cannot do SNAPSHOT smart-clone (item 3) — it falls back to slow host-assisted `copy`,
|
|
# which leaves the default virt StorageClass "degraded" (CDIDefaultStorageClassDegraded).
|
|
# Installing it here (controllers pass) registers the CRDs; the VolumeSnapshotClass + the CDI
|
|
# StorageProfiles that CONSUME them are applied by platform-config (dependsOn: platform).
|
|
#
|
|
# CONTROLLERS/CONFIGS SPLIT (F-MON1): this is the CONTROLLERS half. The snapshot.storage.k8s.io
|
|
# CRDs are registered by the `client/config/crd` base below; the snapshot-controller Deployment
|
|
# (into kube-system, upstream default) reconciles VolumeSnapshots. Custom resources that use these
|
|
# CRDs (the Longhorn VolumeSnapshotClass, item 2) live in platform-config so the CRDs exist first.
|
|
#
|
|
# VERSION (Renovate-maintained): external-snapshotter v8.2.0.
|
|
# * The v8.x line updated its Kubernetes deps to 1.31 at v8.1.0 (this cluster is k3s v1.31.5),
|
|
# so v8.2.x is the conservative, version-matched choice — newer than the 1.31 alignment,
|
|
# older than the v8.4/v8.5 churn.
|
|
# * snapshot.storage.k8s.io CRDs are served at v1 (GA) — driver.longhorn.io speaks v1, so
|
|
# Longhorn CSI snapshots + CDI snapshot-clone work against these CRDs.
|
|
# * The upstream setup manifest pins the controller image to an older v8.0.x tag; the `images`
|
|
# transformer below re-pins it to v8.2.0 so the running controller matches the CRD version.
|
|
# * The `client/config/crd` base also ships the beta VolumeGroupSnapshot CRDs; that feature is
|
|
# gated OFF in the controller (no --enable-volume-group-snapshots arg), so they are inert.
|
|
#
|
|
# Kustomize loads these as REMOTE bases (github.com/...?ref=<tag>) — the same remote-manifest
|
|
# pattern platform/kubevirt uses for the KubeVirt/CDI operators; Flux's kustomize-controller
|
|
# fetches them identically at reconcile.
