When They Go High, We Go Low – Hooking Libc Calls to Debug Kubernetes Apps - Tal Zwick, MetalBear
Description:
Explore a novel approach to debugging cloud-native applications in this 40-minute conference talk from KubeCon + CloudNativeCon. Dive into the innovative technique employed by mirrord, which injects a dynamic library into the process and hooks libc calls to relay operations to the cluster. Learn how this method allows developers to run and debug code locally while simulating cluster conditions. Discover the rationale behind using low-level techniques in cloud-native tooling, gain insights into the underlying Rust code, and witness a live demonstration of mirrord in action. Understand how this approach differs from traditional debugging methods and enhances the development experience for Kubernetes applications.
