As engineers, we’re constantly aware of topics like high availability, reliability, and defensive programming, but often we gloss over what happens to our applications when they behave as expected! Graceful termination and shutdown are common expectations of our container workloads in an orchestrated world. How does termination really work? Can we take advantage of a deeper understanding of Kubernetes’ termination pathways to improve our apps’ behaviours?
In this talk, I will review the Kubernetes approach to Pods, containers, and their runtime behaviours. I’ll cover the various termination pathways that exist via kubectl, kubelet, and the k8s API. The talk will finish with how to use this knowledge to implement The Most Graceful Termination for Kubernetes Apps™.
