5.2. Running Cluster Loader

Procedure

1. Execute Cluster Loader using the built-in test configuration, which deploys five template builds and waits for them to complete:

   $ podman run -v ${LOCAL_KUBECONFIG}:/root/.kube/config:z -i \
   quay.io/openshift/origin-tests:4.5 /bin/bash -c 'export KUBECONFIG=/root/.kube/config && \
   openshift-tests run-test "[sig-scalability][Feature:Performance] Load cluster \
   should populate the cluster [Slow][Serial] [Suite:openshift]"'

   Alternatively, execute Cluster Loader with a user-defined configuration by setting the environment variable for VIPERCONFIG:

   $ podman run -v ${LOCAL_KUBECONFIG}:/root/.kube/config:z \
   -v ${LOCAL_CONFIG_FILE_PATH}:/root/configs/:z \
   -i quay.io/openshift/origin-tests:4.5 \
   /bin/bash -c 'KUBECONFIG=/root/.kube/config VIPERCONFIG=/root/configs/test.yaml \
   openshift-tests run-test "[sig-scalability][Feature:Performance] Load cluster \
   should populate the cluster [Slow][Serial] [Suite:openshift]"'

   In this example, ${LOCAL_KUBECONFIG} refers to the path to the kubeconfig on your local file system. Also, there is a directory called ${LOCAL_CONFIG_FILE_PATH}, which is mounted into the container that contains a configuration file called test.yaml. Additionally, if the test.yaml references any external template files or podspec files, they should also be mounted into the container.
