If the matter is security related, please disclose it privately via --What happened: Creating a pod with a nested subpath volume will cause the pod to fail to start on Windows containerd nodes. What you expected to happen: The pods should start normally. How to reproduce it (as minimally and precisely as possible): Create the following pod on a Windows node with containerd: apiVersion: v1 kind: Pod metadata: annotations: e2e-test-privileged-psp name: pod-subpath-test-downwardapi spec: containers: args: mounttest --filecontentinloop=/test-volume --retrytime=20 image: claudiubelu/agnhost:2.21 name: test-container-subpath-downwardapi volumeMounts: mountPath: /test-volume name: test-volume subPath: downward/podname volumes: downwardAPI: defaultMode: 420 items: fieldRef: apiVersion: v1 fieldPath: path: downward/podname name: test-volume Anything else we need to know?: This issue is causing the following tests to fail on Windows Containerd nodes: [sig-storage] Subpath Atomic writer volumes should support subpaths with downward pod [LinuxOnly] [Conformance] [sig-storage] Subpath Atomic writer volumes should support subpaths with projected pod [LinuxOnly] [Conformance] The tests have the ` tag because we did not support Windows Containerd nodes at the time, and the tests still do not work for Windows Docker nodes. After a fix for this bug is merged, these tests will have to be renamed to enable them for Windows Containerd environments but not for Windows Docker environments. /sig windows Environment: Kubernetes version (use ): v1.21.0-alpha.0.493+ Cloud provider or hardware configuration: N/A OS (e.g: ): Windows Server 1809, Containerd Kernel (e.g. ): 10.0.
