Docker Hub is a cloud-based container registry used to store, manage, and share Docker images. It allows developers to upload and download container images from anywhere.
With Docker Hub, you can push your own Docker images, pull existing images, and share them with your team. It integrates with Docker, Jenkins, and other CI/CD tools for automated deployments.
In simple words, Docker Hub is an online repository where Docker images are stored and shared for building and deploying containerized applications.
