What is Docker Hub?

Docker Hub is a cloud-based registry for Docker images, which allows users to store, share, and manage their Docker container images. This central repository provides a place where developers can publish their images, making it easier to share them with team members or the public. With Docker Hub, users can pull images to run containers locally or push images after building them, enabling a smooth workflow in development and deployment.

Docker Hub supports collaboration among developers by providing features such as image versioning, access control, and automated builds from source code repositories. This makes it a critical component of the Docker ecosystem, facilitating the use of pre-existing images from other developers or organizations to streamline project setup and development processes.

Understanding Docker Hub is essential for efficient container management and deployment, as it simplifies the process of distributing applications by allowing users to leverage existing images rather than building everything from scratch.
