Open Source Summit North America 2022

Envoy Proxy is a foundational layer for many of the innovations propelling the Kubernetes community, including service meshes and cloud-native API gateways. But many engineers understand it only as a black-box, hidden by simplifying levels of abstraction. The purpose of this workshop is to provide a hands-on workshop that will bridge those gaps in Envoy understanding. Participants will explore first principles regarding Envoy architecture, filter chains, and a day-in-the-life of a request. Users will then put those principles to work interactively. Every participant will have access to a computing environment via their web browsers to a Kubernetes K3s platform provisioned with Envoy and supporting tools. From there, users will explore the life of a request through a maze of transforms, custom processing with WebAssembly, and request routing. They will further learn to employ standard Envoy tools like metrics, access logging, and the Tap filter to solve real-world problems.
