Hello from docker!
This message shows the 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 is currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something + ambitious, you can run a Ubuntu container with:
$ docker run-it Ubuntu bash
