Interactively Debugging Kubernetes Applications with Breakpoints

Explore interactive debugging techniques for Kubernetes applications in this 22-minute conference talk. Learn how to overcome challenges such as debugging remote processes, handling container images without debug symbols, and working with separate mount and process namespaces. Discover solutions using ephemeral containers and open-source tools to set breakpoints, watch expressions, and step through code. Follow along with a demonstration of simultaneously debugging multiple cooperating controllers from the Cluster API project using an IDE. Gain insights into common challenges and their solutions, including attaching debuggers, accessing debug information, and locating source code. Equip yourself with the knowledge to effectively debug complex applications in Kubernetes environments.
