Reproducing Production Issues in CI Pipeline Using eBPF

Explore how to leverage eBPF technology for reproducing production issues in CI pipelines in this 29-minute conference talk from KubeCon + CloudNativeCon North America 2022. Dive into the basics of eBPF and discover practical examples of using eBPF-collected data for various software quality use cases. Learn how to utilize the Pixie CNCF sandbox project to extract data and replicate production issues on developer desktops for debugging. Gain insights on integrating these techniques into Continuous Integration pipelines for pre-deployment sanity checks, addressing common challenges like timestamp skew and authentication. Follow along with open-source examples as speakers Matthew LeRay and Omid Azizi demonstrate the power of traffic replay in catching errors and improving software quality.
