Docker Hub is a hosted registry service for discovering, storing, and distributing container images.
- How it is used
- Serves as the default registry for obtaining prebuilt images and distributing application images for deployment.
- How deep it goes
- Walks through tag selection, login, building, pushing, visibility, and production pulls; leaves self-hosting a registry aside.
- Examples
- Uses official NGINX, Python, and Node.js images, then a tagged Python application image pushed to Docker Hub.
- What you can do after
- Operate/configure it by selecting image tags, pushing a built image, and supplying hosted images to a production deployment.
