Deployment strategies​

Services configured with deployment.strategy: rolling get zero-downtime restarts:

  1. New instance starts
  2. Health checks pass
  3. Old instance receives SIGTERM
  4. Grace period allows requests to complete
  5. Old instance stops

Services without rolling deployment stop then start.
