Description Qin Ping 2020-09-22 06:33:21 UTC

Description of Problem:
AWS EBS CSI driver node pods should not run on windows nodes

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-09-21-030155

How Reproducible:
Always


Steps to Reproduce:
1. Setup an OCP cluster with windows nodes
2. Check aws ebs csi operator and drivers

Actual Results:
CSO status is in Progressing status always

AWS EBS CSI driver nodes pods scheduled to windows nodes are stucked in "ContainerCreating" status

[piqin@preserve-storage-server1 local-storage]$ oc get nodes -o wide


Expected Results:
AWS EBS CSI Driver node Pods should not be scheduled to windows nodes.
CSO can be run successfully.

Additional info:
$ oc get nodes -o wide

The manila csi operator and oVirt csi operator should have the same issue, but for 4.6, we don't support windows workers for Openstack and oVirt, so it's ok to fix manila csi operator nd oVirt csi operator later.

For the record, Windows node labels:
    labels:
      beta.kubernetes.io/arch: amd64
      beta.kubernetes.io/instance-type: m5a.large
      beta.kubernetes.io/os: windows

      failure-domain.beta.kubernetes.io/zone: us-east-2a
      kubernetes.io/arch: amd64
      kubernetes.io/hostname: ec2amaz-79adi55
      kubernetes.io/os: windows
      node-role.kubernetes.io/worker: ""
      node.kubernetes.io/instance-type: m5a.large

Linux node:

The driver should target "kubernetes.io/os: linux".
