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

Para lanzar una instancia de la imagen helloworld, primero vamos a comprobar que existe:

# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              05a3bd381fc2        6 weeks ago         1.84kB

Para lanzarla, podemos usar el comando 'docker run':

# docker run -it hello-world
