The Docker Quick Start Terminal is configured to use Docker with the “default” VM.

Click your mouse in the terminal window to make it active.

If you aren’t familiar with a terminal window, here are some quick tips.



The prompt is traditionally a

$

dollar sign. You type
commands into the command line which is the area after the prompt. Your cursor is indicated by a highlighted area or a

|

that
appears in the command line. After typing a command, always press RETURN.

Type the

docker run hello-world

command and press
RETURN.

The command does some work for you, if everything runs well, the command’s output looks like this:

$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
535020c3e8ad: Pull complete
af340544ed62: Pull complete
Digest: sha256:a68868bfe696c00866942e8f5ca39e3e31b79c1e50feaee4ce5e28df2f051d5c
Status: Downloaded newer image for hello-world:latest

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
