Learn Docker Hub with online courses and programs
What is Docker Hub?
Docker Hub is a centralized registry for storing and managing Docker container images. It is a cloud-based service provided by Docker, Inc. and an essential tool for anyone working with the Docker platform.Footnote 1
Containers are the technology that allow software to be easily deployed and run in different environments. They package up code into a standard unit with everything it needs to deploy. A container image is a standalone, executable collection of software that has every component it needs to run, such as the code, libraries, and settings.Footnote 2
With Docker Hub, users can store, share, and manage their own Docker container images, as well as discover and download those created by other users.
