[Docker Hub](https://hub.docker.com/) is a cloud-based repository service provided by [[Docker]] that allows developers to share and access container images. It is the world's largest library and marketplace for container images, providing a centralized platform for storing, managing, and distributing Docker containers. Some key features of Docker Hub include: 1. Image Repository: Docker Hub serves as a repository for storing and sharing container images. Developers can push their own images to Docker Hub or pull existing images from it. 2. Collaboration: It allows developers to collaborate on containerized applications by sharing images with team members or making them publicly available. 3. Automated Builds: Docker Hub offers an automated build feature that triggers builds whenever changes are pushed to a source code repository. This simplifies the process of building, testing, and deploying containerized applications. 4. Official Images: It hosts official images provided by various software vendors or projects, which are thoroughly tested and maintained by their respective teams. These official images provide a trusted base for building containers. 5. Versioning and Tagging: Docker Hub supports versioning and tagging of container images, allowing developers to easily manage different versions of their applications. 6. Integration with Other Tools: Docker Hub integrates with various development tools like GitHub, Bitbucket, and Jenkins, enabling seamless integration into existing workflows. 7. Security Scanning: It provides security scanning capabilities to identify vulnerabilities or potential security risks in container images before deployment. Docker Hub serves as a central hub for the Docker community, facilitating collaboration among developers and making it easy to share and distribute containerized applications across different environments. # References ```dataview Table title as Title, authors as Authors where contains(subject, "Docker") sort title, authors, modified ```
