Discussion:
[X] test pr : kuberenetes/kubernetes 17 June 2021 [x] two weeks soak end date : 1 July 2021 [X] test promotion pr : kubernetes/kubernetes According to this APIsnoop query, there are still some remaining StatafulSet endpoints that are untested. with this query, you can filter untested endpoints by their category and eligibility for conformance. e.g below shows a query to find all conformance eligible untested, stable, core endpoints Create a StatefulSet Patch the StatefulSet List all StatefulSet in the namespace Delete the collection if StatefulSets in the namespace Verify that all StatefulSet was deleted Due to the complexity of setting up the resources for APIService we have used the current e2e test as a template. It has been extended in a for review.
