What ❔

  • API server now doesn't (gracefully) shut down immediately after receiving a signal. Instead, it waits for some time (until the inbound traffic reaches zero), and then starts the graceful shutdown.
  • Some tasks run by the main node are now shutdown-aware.

Why ❔

If the server starts shutting down immediately after receiving a signal (as it does now), this means that it will drop any new traffic, which is not what the K8s load balancer expects.
