Lab 3.4 in CKAD class ask to find multi container pod yaml in the official documentation

Hi @alexanderlvov1,

Multi-container pods have various use cases.
The example pod with nginx and debian containers is a working use case for situations when one container (debian) is used as an update interface to control content and/or the environment of the second container (nginx).
Sidecars have many use cases as well. In exercise 2.4 a simple working example is presented with nginx and fluentd containers. As shown, it only runs the two distinct containers in the pod, however, in a later chapter the fluentd container is fully configured to manage the logs of the nginx container.
Metrics collection is another use of the sidecar multi-container pattern.
Whether predefined container images or custom container images are used in a multi-container pod, their purpose is to allow the containers to interact with each other, either through a shared process namespace, the shared network namespace, shared volume device, etc.
