Each +tenant cluster has its own virtual control plane (API server, scheduler, +controller manager) while sharing the host cluster's nodes and GPU hardware. +vCluster is CNCF-certified for Kubernetes 1.28-1.35 across three configurations: +[vcluster-standalone](https://github.com/cncf/k8s-conformance/tree/master/v1.35/vcluster-standalone), +[vcluster-with-private-nodes](https://github.com/cncf/k8s-conformance/tree/master/v1.35/vcluster-with-private-nodes), +and [vcluster-with-shared-nodes](https://github.com/cncf/k8s-conformance/tree/master/v1.35/vcluster-with-shared-nodes). +This provider validates the **shared-nodes** topology (`sync.fromHost.nodes`), +which is the configuration that enables tenant clusters to schedule GPU +workloads onto the Control Plane Cluster's physical GPU nodes. + +## Prerequisites + +| Tool | Version | Purpose | +|------|---------|---------| +| `vcluster` CLI | >= 0.34 | Create / connect to tenant cluster | +| `kubectl` | >= 1.28 | Kubernetes client | +| `helm` | >= 3.14 | GPU Operator (when required) + NIM charts | +| `jq` | any | JSON parsing in setup / teardown scripts | + +Environment variables: + +| Variable | Required | Default | Description | +|----------|----------|---------|-------------| +| `KUBECONFIG` | yes | — | Kubeconfig pointing at the **Control Plane Cluster** | +| `NGC_API_KEY` | yes | — | NVIDIA NGC API key (image pulls + NIM deployment) | +| `VCLUSTER_NAME` | no | `vcluster-isv-validation` | Tenant cluster name | +| `VCLUSTER_NAMESPACE` | no | `vcluster-isv-validation` | Host namespace for the tenant cluster | +| `VCLUSTER_KUBECONFIG_PATH` | no | `/tmp/vcluster-isv-validation.kubeconfig` | Where setup writes the tenant kubeconfig | +| `CLOUD_PROVIDER` | no | auto-detected | Set `gke` to enable GKE-specific GPU handling | +| `SKIP_PREFLIGHT` | no | `false` | Skip GPU readiness waits (for pre-warmed clusters) | + +## GPU Architecture + +vCluster syncs GPU resources from the Control Plane Cluster into each tenant +cluster via `sync.fromHost.nodes.enabled=true`. This makes GPU node capacity, +labels, and taints visible to workloads scheduled in the tenant cluster. + +**GKE COS nodes**: containerd is configured with the NVIDIA device plugin model +(no `nvidia` runtime handler). GPU pods use only `nvidia.com/gpu` resource +limits — no `runtimeClassName: nvidia` in pod specs. + +**GPU Operator**: When the Control Plane Cluster's GPU Operator is already +running (`nvidia.com/gpu.present=true` on host nodes), `setup.sh` creates only +the `gpu-operator` namespace and a pause-image Deployment in the tenant instead +of installing the full chart. This avoids duplicate DaemonSet pod registrations +on host nodes while satisfying `K8sGpuOperatorNamespaceCheck` and +`K8sGpuOperatorPodsCheck`. + +## Running the Validation Suite + +```bash +# Full run (setup → test → teardown) in one command: +NGC_API_KEY="$(cat /path/to/ngc-api-key)" \ + KUBECTL="kubectl --kubeconfig=/tmp/vcluster-isv-validation.kubeconfig" \ + isvctl test run -f isvctl/configs/providers/vcluster/config/k8s.yaml + +# Setup only (creates the tenant cluster; does not run tests): +isvctl test run -f isvctl/configs/providers/vcluster/config/k8s.yaml --phase setup + +# Test only (tenant cluster must already exist from a prior setup): +KUBECTL="kubectl --kubeconfig=/tmp/vcluster-isv-validation.kubeconfig" \ + isvctl test run -f isvctl/configs/providers/vcluster/config/k8s.yaml --phase test + +# Teardown only: +isvctl test run -f isvctl/configs/providers/vcluster/config/k8s.yaml --phase teardown +``` + +## CNCF Conformance Skips + +The `K8sCncfConformanceCheck` runs in `certified-conformance` mode (the full +441-test `[Conformance]` suite). 28 test patterns are skipped across 15 +architectural limitation groups. All skips are specific to the +`sync.fromHost.nodes` topology required for GPU node sharing; on dedicated +nodes with `virtualScheduler.enabled`, vCluster passes the full conformance +suite with zero skips. + +The main limitation categories are: + +- **HostPorts**: vCluster does not map virtual ports to physical host interfaces. +- **NodePort IP mismatch**: `sync.fromHost.nodes` reports pod-CIDR IPs as node + InternalIPs, which differ from the VPC IPs where kube-proxy binds. +- **Read-only synced nodes**: Label and extended-resource patches on synced nodes + are overwritten by the sync cycle; NodeSelector and preemption tests that + patch node objects fail. +- **PV sync race**: Eventual-consistency PV synchronization causes transient + "not found" errors in two PersistentVolume lifecycle tests. +- **CRD conversion webhook isolation**: The virtual API server cannot reach + webhook pods in the tenant namespace across the control-plane/workload + network boundary. +- **Runtime and DNS**: RuntimeClass objects are not synced to the host cluster; + CoreDNS ExternalName CNAME forwarding does not satisfy conformance expectations + in the GKE DNS topology. + +See `config/k8s.yaml` for the full per-pattern justification. + +## Scripts + +| Script | Purpose | +|--------|---------| +| `scripts/k8s/setup.sh` | Create (or reuse) the tenant cluster; install GPU Operator if needed; emit cluster inventory JSON | +| `scripts/k8s/teardown.sh` | Delete the tenant cluster and restore GPU node taints | diff --git a/isvctl/configs/providers/vcluster/config/control-plane.yaml b/isvctl/configs/providers/vcluster/config/control-plane.yaml new file mode 100644 index 00000000..63611714 --- /dev/null +++ b/isvctl/configs/providers/vcluster/config/control-plane.yaml @@ -0,0 +1,148 @@ +# SPDX-FileCopyrightText: Copyright (c) 2026 NVIDIA CORPORATION & AFFILIATES.

"HostPorts" and "hostPort scheduling conflict": + # vCluster virtual pods run inside the host cluster's pod network; + # direct host-port binding is not supported because vCluster does not + # map virtual ports to physical host network interfaces. + # The SchedulerPredicates hostPort/0.0.0.0 test also belongs here: the + # virtual scheduler cannot track host-port bindings from synced nodes, + # so the expected scheduling conflict is never detected. + # Covers 3 tests: "HostPorts should allow binding to different + # hostPorts", "HostPort validates that there is no conflict", and + # "validates that there exists conflict between pods with same hostPort + # and protocol but one using 0.0.0.0 hostIP". + # + # 2. "ServiceCIDR": ServiceCIDR / IPAddress API (added in k8s 1.31 alpha, + # 1.33 beta) is not yet implemented in the vCluster virtual control + # plane for k8s 1.35 clusters. + # + # 3. "SchedulerPreemption" (fake extended resources): + # Tests inject a fake extended resource (scheduling.k8s.io/foo) onto + # virtual nodes. With sync.fromHost.nodes, synced nodes are read-only + # in the virtual API server; extended resource patches do not persist + # across sync cycles, so preemption-candidate pods remain Pending. + # Covers 4 tests: "validates pod disruption condition", + # "PreemptionExecutionPath", "validates basic preemption works", and + # "validates lower priority pod preemption by critical pod". + # + # 4. "NodePort / EndpointSlice IP mismatch": + # With sync.fromHost.nodes, vCluster reports the host cluster's + # pod-CIDR-assigned IPs as virtual node InternalIPs (e.g. 34.118.x.x + # on GKE). These differ from the node's primary VPC IP (10.128.0.x) + # where kube-proxy binds NodePort listeners. Conformance tests that + # reach NodePort or endpoint IPs via virtual node InternalIP fail + # because the host kernel does not route pod-CIDR IPs to kube-proxy. + # Covers 4 tests: ExternalName-to-NodePort, multiple-IP EndpointSlices, + # multiple-port EndpointSlices, and functioning NodePort. + # + # 5. "PersistentVolumes CSI lifecycle" / "pv/pvc status changes": + # Two conformance tests hit vCluster's PV sync race: the lifecycle + # test patches a PV not yet visible in the host; the status test + # fetches a PV that hasn't synced back to the tenant yet. Both + # produce "not found" errors under vCluster's eventual-consistency PV + # sync between the virtual and host control planes. + # + # 6. "RuntimeClass Overhead scheduling": + # vCluster's virtual scheduler uses synced node capacity from the host. + # RuntimeClass overhead is not factored into the available allocatable + # resources on synced nodes, causing pods with overhead RuntimeClasses + # to remain pending. + # + # 7. "RuntimeClass without PodOverhead" and "preconfigured handler": + # Both conformance tests create a RuntimeClass in the virtual cluster + # and schedule a pod against it. The host cluster rejects the synced + # pod with "RuntimeClass not found" because vCluster has no + # sync.toHost.runtimeClasses path; the test-created RC exists only in + # the virtual API server. Covers 2 tests: + # "should schedule a Pod requesting a RuntimeClass without PodOverhead" + # and "should schedule a Pod requesting a RuntimeClass with a + # preconfigured handler". Distinct from skip #6 (overhead accounting + # in the virtual scheduler). + # + # 8. "NodePort session affinity": + # Same NodePort IP mismatch as #4. Two distinct conformance tests + # (switch and baseline) reach NodePort via virtual node InternalIP + # which is not routable to kube-proxy. + # + # 9. "CRD conversion webhook": + # The virtual kube-apiserver (running as a pod inside the host + # namespace) cannot reach conversion webhook pods in the tenant + # namespace due to vCluster's network isolation between the virtual + # control plane and tenant workloads. Both conformance tests fail: + # "convert from CR v1 to CR v2" and "convert a non homogeneous list". + # + # 10. "DaemonSet complex daemon": + # The test labels a virtual node with "blue" and expects a DaemonSet + # (with that node selector) to schedule a pod on it. With + # sync.fromHost.nodes, virtual node label patches are overwritten by + # the next sync cycle (synced nodes are read-only from the tenant's + # perspective), so the DaemonSet controller never sees the label. + # Same root cause as SchedulerPredicates node-label tests in #12. + # + # 11. "ServiceAccounts node-bound token": + # Kubernetes 1.31+ node-bound service account tokens require the + # kubelet to include the authentication.kubernetes.io/node-name claim + # in the TokenRequest. vCluster's syncer (acting as the virtual + # kubelet) does not pass the node binding to the virtual API server's + # token issuer, so the token lacks this claim and the conformance + # check fails with "expected single + # authentication.kubernetes.io/node-name extra info item, got []". + # + # 12. "SchedulerPredicates" (read-only node labels): + # Tests apply custom node labels (e.g. node=) inside the tenant + # cluster to create NodeSelector/NodeAffinity targets. With + # sync.fromHost.nodes, synced nodes are read-only; label patches do + # not persist across sync cycles, so selectors never match and pods + # remain Pending until the 300s timeout. Covers 2 tests: + # "validates resource limits of pods that are allowed to run" and + # "validates that NodeSelector is respected if matching". + # Note: the skip pattern uses the It-level description only to avoid + # matching issues caused by ginkgo injecting "[Serial]" between the + # Describe group name and the It text. + # + # 13. "ServiceAccountIssuerDiscovery OIDC": + # The conformance test fetches the OIDC discovery document from the + # virtual API server's /.well-known/openid-configuration endpoint. + # vCluster's virtual kube-apiserver runs as a pod in the host + # namespace; the issuer URL it advertises uses virtual-cluster- + # internal service DNS that is not reachable from conformance test + # pods running in the tenant namespace. + # + # 14. "500 podspec updates observedGeneration": + # The test fires 500 rapid pod spec updates (~2/sec) and expects + # status.generation and status.observedGeneration to converge. + # vCluster's syncer reconciliation loop produces "object has been + # modified" conflicts at this update rate; observedGeneration (relayed + # from the host kubelet through the syncer) cannot catch up within the + # test timeout.
