# 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.
|
|
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 [`scratch`](https://registry.hub.docker.com/_/scratch/) image effectively. See [`hello.asm`](https://github.com/docker-library/hello-world/blob/master/hello.asm) in https://github.com/docker-library/hello-world for the source code of the `hello` binary included in this image.
