KubeCon + CloudNativeCon Europe 2025

This presentation takes an in-depth look at the path of an API request (e.g. a user sends a request to create a Pod through kubectl create). We take a deep dive into the phases a request passes through, in a chronological order, starting with its arrival at the k8s API Server, and ending in its departure carrying a response to the caller.

This talk will not dive into any code snippets, but rather will use easy to understand diagrams that dig deep into k8s architecture, and side by side, it will show the related observability artifacts (log, audit, metrics snapshot, and error messages) and clarify their implications. To our knowledge, no kubecon talk has covered this topic from an operator's perspective.

After attending this talk, the audience, whether they are an admin, an SRE, or a DevOps professional, will walk away with a much clearer understanding of "how things work in Kubernetes"; the new insights will make them more effective at finding root causes for complex cluster issues.
