Issue

  • Allowed to use the existing images on the same node with running pods on it in another namespaces regardless of granting "system:image-puller".
  • For example of this issue, "A" pod with "A" image is scheduled on "A" node, then "B" pod of another project on the same node can run with "A" image without "system:image-puller" for the "A" image of a different project.
