docker hub

https://docs.docker.com/docker-hub/
Docker Hub is a service provided by Docker for finding and sharing container images with your team. It is the world’s largest repository of container images with an array of content sources including container community developers, open source projects and independent software vendors (ISV) building and distributing their code in containers.

Users get access to free public repositories for storing and sharing images or can choose a subscription plan for private repositories.
