Different between Registry vs Repository in Docker?

What are the key differences between a Docker Registry and a Docker Repository in terms of their purpose, structure, hierarchy, and practical usage when building, storing, tagging, pushing, and pulling container images?

A Docker Registry is a service that hosts multiple repositories for storing and distributing container images, while a Docker Repository is a specific collection within a registry that groups tagged versions of a single image or application, such as "myapp:latest" and "myapp:v1.0".

You can acknowledge the answer as accurate and then add more clarity and detail for deeper understanding. For example:

That explanation precisely captures the distinction between a Docker Registry and a Docker Repository. To add, think of the Docker Registry as the centralized service or server that hosts many repositories, acting much like a cloud storage platform for container images. Within a registry, each Docker Repository functions like a specific folder containing all the versions (tags) of a particular application image, such as "myapp:latest" or "myapp:v1.0". This hierarchy helps organize images efficiently for building, tagging, pushing, and pulling in container workflows. Understanding this structure is key to managing container images effectively in development and deployment pipelines

Yep, exactly! The registry is the server where all the Docker images live, and the repository is basically one folder or project inside that registry that holds different versions of an image. Nice explanation

Can you explain how tagging works within a Docker repository and why it's important for managing image versions?

In case of this qs, It's ok to discuss I think.
