Example output

console
$ docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

How is this image created?

This image is a prime example of using the https://hub.docker.com/_/scratch/ image effectively. See https://github.com/docker-library/hello-world/blob/master/hello.c in https://github.com/docker-library/hello-world for the source code of the hello binary included in this image.

Because this image consists of nothing but a single static binary which prints some text to standard output, it can trivially be run as any arbitrary user (docker run --user $RANDOM:$RANDOM hello-world, for example).
