What it shows

  • Endpoint removal and preStop hooks trigger concurrently upon pod deletion.
  • A SIGTERM signals your app to stop accepting traffic and flush buffers.
  • terminationGracePeriodSeconds guarantees a SIGKILL if jobs hang.

The takeaway

Graceful shutdowns prevent dropped connections by synchronizing network endpoint teardown with SIGTERM handling.
