Guide to K8s Container Events: Tracking, Errors & Collection

Kubernetes container events are crucial to understand and manage, as they can provide insights into why containers fail or terminate unexpectedly. To track these events, it's essential to have a deep understanding of Kubernetes' tracking mechanisms, error reporting, and collection methods. The guide highlights the importance of monitoring nodes, containers, and Pods, and explains how Pod status and container states can be accessed through the Kubernetes API. It also discusses the limitations of relying solely on exit codes for troubleshooting and introduces an alternative approach to focus on structured container restart events with exit codes and reason. By using this approach, developers can gain a better understanding of applicative issues behind container terminations or restarts without installing additional third-party tools.
