Invisible Debugging for Docker Workloads on Ubuntu GCP: eBPF in Action

Modern production systems often restrict SSH access, making traditional debugging on Ubuntu instances increasingly difficult. In this talk, I share real-world SRE experiences debugging live issues on Ubuntu virtual machines running on GCP, without logging into them.

Using eBPF-based tools on Ubuntu, I demonstrate how to trace system calls, analyze network behavior, and identify performance bottlenecks in real time. Through actual incident scenarios, we’ll uncover how Ubuntu’s kernel capabilities combined with eBPF enable “invisible debugging,” helping engineers resolve critical issues faster without disrupting production systems.
