ShortLongDescription
-c--configPath to the configuration file. When specified, reloads the configuration and restarts all services with the new settings
-s--serviceName of a specific service to restart. If not specified, all services are restarted

​
Restart specific service

​
Restart with new configuration

$ sysg restart --config production.yaml
Reloads configuration and restarts all services.

​
Deployment strategies

Services configured with deployment.strategy: rolling get zero-downtime restarts:
  1. New instance starts
  2. Health checks pass
  3. (Optional) blue/green switch_command shifts traffic to candidate slot
  4. Old instance receives SIGTERM
  5. Grace period allows requests to complete
  6. Old instance stops
Services without rolling deployment stop then start. For deployment scripts, prefer: 
sysg restart --config <config> --daemonize
This keeps restart behavior explicit when supervisor detection is unavailable.
