go-graceful-shutdown

What problem does it solve?

This Skill addresses the critical issue of dropped connections and incomplete operations during microservice deployments or restarts by implementing a robust graceful shutdown mechanism.

Core Features & Use Cases

• Signal Handling: Catches OS signals like SIGTERM and SIGINT to initiate shutdown.
• Draining Requests: Allows in-flight gRPC requests to complete before shutting down the server.
• Resource Cleanup: Ensures orderly shutdown of database connections and background workers.
• Dependency Ordering: Manages the shutdown sequence of various components based on their dependencies.
• Configurable Timeout: Provides a configurable duration for the shutdown process.
• Use Case: When deploying a new version of a Go microservice in Kubernetes, this skill ensures that active user requests are not abruptly terminated, preventing data loss and improving user experience.

Quick Start

Add a graceful shutdown manager to my Go service that handles OS signals and drains in-flight gRPC requests.
