== Image Registry ==

!DockerHub is, first and foremost, a container image registry.

With `docker(1)` specifically, this is the default registry. Images can be pulled by simply specifying the namespace, name, and tag (i.e. `internetsystemsconsortium/bind9:9.18`). For 'official' images, the namespace is omitted (i.e. `nginx:latest`).

With other container managers, the registry is accessed by `docker.io`. (The above images would be available from `docker.io/internetsystemsconsortium/bind9:9.18` and `docker.io/library/nginx:latest`, respectively.)
