Description Sebastian Jug 2019-10-15 15:27:39 UTC
Description of problem:
Cluster Loader is a scale test tool (https://docs.openshift.com/container-platform/4.1/scalability_and_performance/using-cluster-loader.html#running_cluster_loader_)

When running it without specifying user provided configuration, it does not successfully locate the built in test templates.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.sudo podman run -v ${LOCAL_KUBECONFIG}:/root/.kube/config -i
quay.io/openshift/origin-tests:4.1 /bin/bash -c 'export KUBECONFIG=/root/.kube/config && openshift-tests run-test "[Feature:Performance][Serial][Slow] Load cluster should load the cluster [Suite:openshift]"'
2. Fail

Actual results:
Error stating unable to find template files in built in config.

Expected results:
Succesful execution of built in config by deploying test data templates.

Comment 3 Sebastian Jug 2019-10-16 15:43:48 UTC
It seems that the change in origin:

Neuters the function that we were using to find the viperConfig path, now always returning "" rather than the path.
Will need to work around this in the Cluster Loader test.

Comment 5 Sebastian Jug 2019-10-18 12:26:50 UTC
Cluster Loader is part of extended test and has no component of its own

Comment 7 Sebastian Jug 2019-10-20 18:47:57 UTC
Fixed in https://github.com/openshift/origin/pull/23994

Comment 11 Sebastian Jug 2019-11-25 15:16:53 UTC
The docs will need to be updated as the openshift-tests have moved from quay.io/openshift/origin-tests:4.3 to the new repo: registry.svc.ci.openshift.org/ocp/4.3:tests

Comment 12 Siva Reddy 2019-11-25 16:14:49 UTC
Cluster loader is now able to find the default config when there is no config specified.

Note: the image to get the openshift-tests is "registry.svc.ci.openshift.org/ocp/4.3:tests" and not "quay.io/openshift/origin-tests:4.3"

Steps to Verify:
1. pull the openshift tests from the "registry.svc.ci.openshift.org/ocp/4.3:tests"
    podman pull registry.svc.ci.openshift.org/ocp/4.3:tests
2. Run the tests with out specifying a config.
    sudo podman run -v ${LOCAL_KUBECONFIG}:/root/.kube/config:z -i registry.svc.ci.opensh
ift.org/ocp/4.3:tests /bin/bash -c 'export KUBECONFIG=/root/.kube/config && openshift-tests run-test "[Feature:Performance][Serial][Slow
] Load cluster should load the cluster [Suite:openshift]"'
3. Note that the cluster loader doesn't fail with the error "unable to find pod/template file ./test/extended/testdata/cluster/quickstarts/cakephp-mysql.json" but it successfully creates projects with different templates.
4. # oc projects | grep clusterloader
