It is used for storing, distributing, and downloading Docker images. --- ### **What Docker Hub allows** - storing your own images (public or private); - downloading other people's ready-made images (for example, `nginx`, `postgres`, `node`); - versioning images with tags (`:latest`, `:1.2.0`); - connecting CI/CD for automatic image `push`. --- ### **A typical workflow** ```bash docker pull nginx # download an image docker login # log in docker push myrepo/app # push your image ``` --- ### **Why it is useful** - most projects pull their base images from there; - it cuts down development time - no need to build everything from scratch; - it makes it easy to deliver images to servers and to the cloud. --- **Summary:** Docker Hub is the main public repository of Docker images, which stores both official images and community images, and which is used by default by the `docker pull` client.For the reviewerNote to the moderator (optional)Visible only to the moderator.
