In Kubernetes, which description best fits a "Chart"?

A "Chart" in Kubernetes specifically refers to a set of files that describe Kubernetes resources. These files define how to install and manage applications, encapsulating all necessary components needed for deployment. A Chart typically includes templates, configuration values, and metadata that work together to deploy and configure applications within a Kubernetes environment.

Charts can be thought of as packages that contain everything required to run a piece of software in a Kubernetes cluster, providing a standardized way to manage complex applications. They allow developers to maintain and share applications consistently across different environments. This structured approach not only simplifies the deployment process but also enhances the ability to version and update applications seamlessly.

The other options do not accurately describe a Chart. A collection of Docker containers refers to an entirely different aspect of containerization rather than Kubernetes resource management. A group of Kubernetes nodes pertains to the hardware or virtual machines that run your workloads, while a type of cloud storage relates to how data is stored, none of which capture the essence of what a Chart represents in the Kubernetes ecosystem.
