Explore the intricate journey of a packet through a service mesh in this 33-minute conference talk presented by Kevin Leimkuhler from Buoyant and Doug Jordan from Airbnb at a CNCF event. Trace the packet's path between a meshed client and server, examining how it changes after installing a service mesh and the additional hops introduced. Discover the networking rule modifications that enable proxy interception of traffic and gain insights into observing these changes within the kernel. Delve into Kubernetes networking debugging techniques, learning how to effectively use debug containers for traffic observation between other containers. Familiarize yourself with tools for monitoring traffic and gain a comprehensive understanding of the behind-the-scenes workings of a service mesh and packet travel within it.
