Container Registries

Container registries are like GITHUB, but for docker images. Docker Hub is an example of a public registry. Registries are split into repositories, where you can run docker pull from or use docker push to. Docker Hub uses a username, repository name, and a tag to name everything. This topic will be much clearer when you interact with a docker registry, such as Docker Hub, where you can experience pulling and pushing container images, logging into the registry, and tagging images.
