Verify the Tungsten Fabric deployment¶

This section explains how to use the tungsten-pytest test set to verify your Tungsten Fabric (TF) deployment. The tungsten-pytest test set is part of the TF operator and allows for prompt verification of the Kubernetes objects related to TF and basic verification of the TF services.

To verify the TF deployment using tungsten-pytest:

1. Enable the tf-test controller in the TF Operator resource for the Operator to start the pod with the test set:

   spec:
     controllers:
       tf-test:
         tungsten-pytest:
           enabled: true
   

2. Wait until the tungsten-pytest pod is ready. To keep track of the tests execution and view the results, run:

   kubectl -n tf logs -l app=tf-test
   

3. Optional. The test results are stored in the tf-test-tungsten-pytest PVC. To obtain the results:

   1. Deploy the pod with the mounted volume:

      # Run pod and mount pvc to it
      cat <<EOF | kubectl apply -f -
      apiVersion: v1
      kind: Pod
      metadata:
        name: tf-test-results-pod
        namespace: tf
      spec:
        volumes:
          - name: tf-test-data-volume
            persistentVolumeClaim:
              claimName: tf-test-tungsten-pytest
        containers:
          - name: tempest-pvc-container
            image: ubuntu
            command: ['sh', '-c', 'sleep infinity']
            volumeMounts:
              - mountPath: "/tungsten-pytest/data"
                name: tf-test-data-volume
      EOF
      

   2. Copy the results locally:

      kubectl -n tf cp tf-test-results-pod:tungsten-pytest/data/results.xml results.xml
      

   3. Remove the Tempest test results pod:

      kubectl -n tf delete pod tf-test-results-pod
      

4. Disable the tf-test controller:

   kubectl -n tf patch tfoperator openstack-tf --type='json' -p='[{"op": "replace", "path": "/spec/controllers/tf-test/tungsten-pytest/enabled", "value": false}]'
   

5. Manually remove the pod with tests:

   kubectl -n tf delete pod -l app=tf-test
