A call to the PreStop hook fails > if the container is already in a terminated or completed state and the hook > must complete before the TERM signal to stop the container can be sent. The > Pod's termination grace period countdown begins before the PreStop hook is > executed, so regardless of the outcome of the handler, the container will > eventually terminate within the Pod's termination grace period. No > parameters are passed to the handler.
