$ 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.
(Assuming it was not already locally available.)
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

$ docker images hello-world
REPOSITORY TAG IMAGE ID VIRTUAL SIZE
hello-world latest 565a9d68a73f 922 B
If you have any questions about the image, please contact us through a GitHub issue or in the IRC channel #docker-library on Freenode.
If you want to contribute new features or updates, we are always thrilled to receive pull requests, and do our best to process them as fast as possible.
We recommend discussing your plans through a GitHub issue before starting to code - especially for more ambitious contributions. This gives other contributors a chance to point you in the right direction, give feedback on your design, and maybe point out if someone else is working on the same thing.
