What is graceful shutdown? Not many people are aware of this term and how to use it properly. Recently every app can be deployed using containers and orchestrators of containers, which makes this problem even more important.

So our workloads must be “Cloud Native Apps” which means it relies upon some orchestrators like Kubernetes or another container orchestrator. The lifecycle usually includes killing workloads and we need to adapt to it properly. When the orchestrator sends special signals to restart the workload we need to understand what’s is signals and why we have all of them.

So in this talk, I’ll walk you through different patterns of how to add graceful shutdown to your services and apps, why it’s important, and also how to investigate and adapt to orchestrators and be in sync with them about signals. Also, I’ll demonstrate how to shut down long-running tasks and connections gracefully so your users will be happy during releases and other different maintenance work.
