Graceful Shutdown in Go: Practical Patterns
Go applications can implement graceful shutdown by handling termination signals (SIGTERM, SIGINT) via os/signal or signal.NotifyContext. Shutdown must complete within a specified timeout (e.g., Kubernetes’ terminationGracePeriodSeconds)…
Even after a pod is marked for termination, it might still receive traffic for a few moments because the system needs time to update the service and load balancer. A readiness probe determines when a container is prepared to accept traffic by periodically checking its health through configured methods like HTTP requests, TCP connections, or command executions. The client will immediately receive a connection error, such as ECONNRESET(‘socket hang up’) However, long-running handlers that are not interacting with the network may continue running in the background.
