How do I get a docker image?

Images are automatically pulled when you install a container, you can specially use the docker pull command to get the image you require as well.
The terminology used to get a docker image is called "pull". So to pull a docker image run:
$ docker pull centos latest: Pulling from centos 47d44cb6f252: Pull complete 168a69b62202: Pull complete 812e9d9d677f: Pull complete 4234bfdd88f8: Pull complete ce20c473cd8a: Pull complete centos:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security. Digest:
