Description Tinashe Chipomho 2021-05-06 11:57:40 UTC
Description of problem:
Running conformance tests on ocp4.7 with RAN DU profile results in resource (CPU, memory) request errors

Version-Release number of selected component (if applicable):
Client Version: 4.7.0-0.nightly-2021-03-14-223051
Server Version: 4.7.0-0.nightly-2021-03-14-223051
Kubernetes Version: v1.20.0+bafe72f

How reproducible:
Run origin-tests against an ipv6 only enabled cluster. 

Steps to Reproduce:
1. Git clone https://github.com/openshift/origin.git into the test environment or 
 Extract the binaries - oc image extract {{ ocp_tests_image }} --path 
2. Make the files executable - chmod a+x openshift-tests
3. Navigate to the root directory and run “make” to generate the binaries 
  For disconnected environments, mirror images needed for tests like - 
 ./openshift-tests images --to-repository {{ regfqdn }} > e2e-image-mirror-list
4. oc image mirror -f e2e-image-mirror-list
5. Run tests like - ./openshift-tests run {{ ocp_test_suite }} --from-repository {{ local_registry }} \ --junit-dir . --output-file ocp-test-suite.log
Actual results:

Expected results:
fail [github.com/onsi/ginkgo@v4.7.0-origin.0+incompatible/internal/leafnodes/runner.go:113]: Mar 29 09:15:03.229: Pods in platform namespaces are not following resource request/limit rules or do not have an exception granted:
apps/v1/DaemonSet/openshift-ovn-kubernetes/ovnkube-master/container/sbdb does not have a cpu request (rule: "apps/v1/DaemonSet/openshift-ovn-kubernetes/ovnkube-master/container/sbdb/request[cpu]")
  apps/v1/DaemonSet/openshift-ovn-kubernetes/ovnkube-master/container/sbdb does not have a memory request (rule: "apps/v1/DaemonSet/openshift-ovn-kubernetes/ovnkube-master/container/sbdb/request[memory]")
