Understanding Sidecar Containers

Описание: Regular Kubernetes users are likely familiar with the sidecar pattern. The sidecar pattern has enjoyed popularity in the Kubernetes world for its ability to extend the functionality of a primary container with little modification to the main workload. But have you ever taken the time to really understand what is going on inside of a sidecar container at the operating system level?

In this video, we take a closer look at the underlying concepts that enable sidecar containers to function. We'll look at a realistic example (the Vault Agent sidecar) to gain a better understanding of how Kubernetes enables the sidecar pattern.
