Docker Hub repositories allow you share container images with your team, customers, or the Docker community at large.

Docker images are pushed to Docker Hub through the docker push command. A single Docker Hub repository can hold many Docker images (stored as tags).

You can add multiple images to a repository, by adding a specific :<tag> to it (for example docs/base:testing). If it’s not specified, the tag defaults to latest.

Purchase plans starting at $7/ month for 5 private repositories
