[jira] [Created] (YUNIKORN-1699) Plugin mode doesn't work on Kubernetes 1.27 cluster

Craig Condit created YUNIKORN-1699:
--------------------------------------

             Summary: Plugin mode doesn't work on Kubernetes 1.27 cluster
                 Key: YUNIKORN-1699
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1699
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: shim - kubernetes
            Reporter: Craig Condit


The scheduler plugin mode doesn't work when running under Kubernetes 1.27, as the v1beta1 version of CSIStorageCapacity was removed from the API server. This prevents the plugin from starting up as the informers won't sync, and scheduling is non-functional.

As v1 was not available until 1.24, so we will need to build against at least 1.24. However, this will remove compatibility for running on 1.21 through 1.23. This is tricky, as 1.22 and especially 1.23 are still widely deployed.

See https://issues.apache.org/jira/browse/YUNIKORN-1196?focusedCommentId=17531921&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17531921 for breaking changes in the API server identified the last time we upgraded our dependency on Kubernetes.

Opening this now to drive visibility and facilitate discussion.
