What is the main purpose of Docker Hub?

The main purpose of Docker Hub is to provide a public repository for sharing Docker images. Docker Hub serves as a centralized platform where developers and teams can store, share, and distribute Docker images. It allows users to access a vast library of pre-built images contributed by the community and official sources, making it easier to discover and use software packaged in containers.

This public repository facilitates collaboration, as users can push their own images to Docker Hub or pull existing images for their applications. This sharing feature enhances the developer experience by reducing the time required to set up environments and deploy applications. By leveraging Docker Hub, teams can streamline their workflows and ensure consistent deployment of applications across different environments.
