When we scale up a worker in origin e2e test, the node that gets created has the following taints: Sep 19 02:48:24.028: INFO: node/ci-op-469ls8mj-129d4-b5f8x-worker-7hmtt had unexpected taints: []v1.Taint{v1.Taint{Key:"kubernetes.io/e2e-taint-key-43604c41-e393-4fb0-ae30-904ffbc870d0", Value:"testing-taint-value-fd73330a-2df4-4fd2-96e4-a432000a1cd7", Effect:"PreferNoSchedule", TimeAdded:(*v1.Time)(nil)}} Searching through the repo, various pod logs, and machines/machinesets, it's unclear how or why these taints are getting applied. After fixing this bug, this issue might go away: https://bugzilla.redhat.com/show_bug.cgi?id=1880738 It's still unclear why these taints are being applied, so we need to ensure that we either account for them or have them stop being applied.
