Secure and Debuggable: Debugging Slim, Scratch and Distroless Kubernetes Containers

Explore techniques for debugging slim, scratch, and distroless Kubernetes containers in this informative conference talk. Learn how to overcome the challenges of debugging optimized containers with reduced attack surfaces, where traditional methods like "kubectl exec" or "kubectl cp" are not available. Discover the power of Ephemeral Containers, a feature that became generally available in Kubernetes 1.25, and how it can be leveraged as a debugging tool sidecar. Gain insights into using "kubectl debug" with Ephemeral Containers, including its capabilities and limitations. Explore alternative methods of utilizing Ephemeral Containers without relying on "kubectl debug". Examine existing debugging tool container images and their practical applications in your debugging workflow.
