Understanding what multi-container Pods are

In this section, we'll learn about the core concepts of Pods for managing several containers at once by discussing some concrete examples of multi-container Pods.

Then, we will create and delete a Pod made up of at least two and discover how to access its logs. After that, we'll learn how to access a specific container within a Pod containing multiple containers. Finally, we will learn how to access the logs of a specific container within a running Pod.

Concrete scenarios where you need multi-container Pods

If your application requires multiple containers to function properly, then those containers should be launched and managed through a single Pod.

When the containers are supposed to work together, you should group them into a single...
