Run Conformance Tests

You will need a cluster with at least 2 nodes. The steps below assume that you will use a local minikube cluster. We executed the test on a minikube instance with docker driver (default auto-detected by system).

1. Create a multinode minikube cluster

bash
minikube start --kubernetes-version 1.34.0 --nodes=2

2. Create the vcluster

Create a file called vcluster.yaml with the following content:

yaml
controlPlane:
  advanced:
    virtualScheduler:
      enabled: true
  backingStore:
    etcd:
      deploy:
        enabled: true
        statefulSet:
          image:
            tag: 3.6.4-0
  distro:
    k8s:
      apiServer:
        extraArgs:
          - --service-account-jwks-uri=https://kubernetes.default.svc.cluster.local/openid/v1/jwks
      enabled: true
      image:
        tag: v1.34.0
  statefulSet:
    scheduling:
      podManagementPolicy: OrderedReady

networking:
  advanced:
    proxyKubelets:
      byHostname: false
      byIP: false

sync:
  fromHost:
    csiDrivers:
      enabled: false
    csiStorageCapacities:
      enabled: false
    nodes:
      enabled: true
      selector:
        all: true
  toHost:
    persistentVolumes:
      enabled: true
    priorityClasses:
      enabled: true
    storageClasses:
      enabled: true

Create a virtual cluster using vcluster version 0.27.0 (latest) using the following command:

bash
# Create the vCluster
vcluster create vcluster -n vcluster -f vcluster.yaml

3. Run Tests

Download a binary release of the CLI, or build it yourself by running:

bash
go install github.com/vmware-tanzu/sonobuoy@latest

Deploy a Sonobuoy pod to your cluster with:

bash
sonobuoy run --mode=certified-conformance --dns-pod-labels=k8s-app=vcluster-kube-dns

View actively running pods:

bash
sonobuoy status

To inspect the logs:

bash
sonobuoy logs

Once sonobuoy status shows the run as completed, copy the output directory from the main Sonobuoy pod to a local directory:

bash
outfile=$(sonobuoy retrieve)

This copies a single .tar.gz snapshot from the Sonobuoy pod into your local . directory. Extract the contents into ./results with:

bash
mkdir ./results; tar xzf $outfile -C ./results
