Merge pull request #99735 from bobbypage/beta-graceful-shutdown 
Promote kubelet graceful node shutdown to beta
 2021-03-05 17:23:42 -08:00

893f5fd4f0 Promote kubelet graceful node shutdown to beta 
- Change the feature gate from alpha to beta and enable it by default

- Update a few of the unit tests due to feature gate being enabled by
  default

- Small refactor in `nodeshutdown_manager` which adds `featureEnabled`
  function (which checks that feature gate and that
  `kubeletConfig.ShutdownGracePeriod > 0`).

- Use `featureEnabled()` to exit early from shutdown manager in the case
  that the feature is disabled

- Update kubelet config defaulting to be explicit that
  `ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods` default to
  zero and update the godoc comments.

- Update defaults and add featureGate tag in api config godoc.

With this feature now in beta and the feature gate enabled by default,
to enable graceful shutdown all that will be required is to configure
`ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods` in the
kubelet config. If not configured, they will be defaulted to zero, and
graceful shutdown will effectively be disabled.

b451c15bf7 kubelet: Fix race when KillPod followed by IsPodPendingTermination 
Ensures the pod to be pending termination or be killed, after
(*podKillerWithChannel).KillPod has been returned, by limiting
one request per pod in (*podKillerWithChannel).KillPod.

Remove pkg/util/mount (moved out of tree) 
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.
