Deep dives
Introduction to Inspector Gadget and its Purpose
Inspector Gadget is a collection of eBPF-based tools designed for inspecting and debugging Kubernetes pods at the kernel level, offering a centralized management system through a Kubernetes daemon set. Originally developed as a project to enhance existing BPF tools for Kubernetes, it addresses the lack of built-in observability features found in Kubernetes itself. Key motivations behind the project include the need for performance measurement, policy violation auditing, and network traffic monitoring, which traditional methods may not adequately provide. The project evolved from its inception with a focus on simplifying application management on Kubernetes while enhancing observability through kernel data.
