Automatic merge from submit-queue Fix mount collision timeout issue Short- or medium-term workaround for #29555. The root issue being fixed here is that the recent attach/detach work in the kubelet uses a unique volume name as a key that tracks the work that has to be done for each volume in a pod to attach/mount/umount/detach. However, the non-attachable volume plugins do not report unique names for themselves, which causes collisions when a single secret or configmap is mounted multiple times in a pod. This is still a WIP -- I need to add a couple E2E tests that ensure that tests break in the future if there is a regression -- but posting for early review. cc @kubernetes/sig-storage Ultimately, I would like to refine this a bit further. A couple things I would like to change: 1. `GetUniqueVolumeName` should be a property ONLY of attachable volumes 2. I would like to see the kubelet apparatus for attach/mount/umount/detach handle non-attachable volumes specifically to avoid things like the `WaitForControllerAttach` call that has to be done for those volume types now |
