Documented steps

  1. Add `stop_grace_period: 30s` (duration with units: us/ms/s/m/h) to give the process time to shut down before SIGKILL. Default is 10 seconds.
  2. Set `stop_signal: SIGTERM` (default) or another signal (e.g. SIGQUIT) to tell the container what signal to send on stop.
  3. The container should trap/forward the signal (and ideally run an init/PID1 that reaps, e.g. `init: true`) so it can clean up within the grace period.
