      Goals

      • Make kubelet aware of underlying node shutdown event and trigger pod termination with sufficient grace period to shutdown properly
      • Handle node shutdown in cloud-provider agnostic way
      • Introduce minimal shutdown delay in order to shutdown node soon as possible (but not sooner)
      • Focus on handling shutdown on systemd based machines

      Story 1

      • As a cluster administrator, I can configure the nodes in my cluster to allocate X seconds for my pods to terminate gracefully during a node shutdown

      • As a developer I can expect that my pods will terminate gracefully during node shutdowns
