Discussion:
[x] test approval issue : [x] test pr : 18 May 2023 [x] two weeks soak end date : 01 June 2023 [x] test promotion pr : According to following APIsnoop query, there are still 2 PodEphemeralcontainers endpoints that are not tested for Conformance. Using a number of existing e2e test practices a new has been created to address these 2 endpoints. The e2e logs for this test are listed below. This query shows the following podephemeralcontainers endpoints are hit within a short period of running this e2e test. If a test with these calls gets merged, test coverage will go up by 2 points This test is also created with the goal of conformance promotion. /sig testing /sig architecture /area conformance
